.. _configuration-salt-master: =========================== Configuring the Salt Master =========================== The Salt system is amazingly simple and easy to configure, the two components of the Salt system each have a respective configuration file. The ``salt-master`` is configured via the master configuration file, and the ``salt-minion`` is configured via the minion configuration file. .. seealso:: :ref:`Example master configuration file `. The configuration file for the salt-master is located at ``/etc/salt/master`` by default. Atomic included configuration files can be placed in ``/etc/salt/master.d/*.conf``. Warning: files with other suffixes than .conf will not be included. A notable exception is FreeBSD, where the configuration file is located at ``/usr/local/etc/salt``. The available options are as follows: .. _primary-master-configuration: Primary Master Configuration ============================ .. conf_master:: interface ``interface`` ------------- Default: ``0.0.0.0`` (all interfaces) The local interface to bind to, must be an IP address. .. code-block:: yaml interface: 192.168.0.1 .. conf_master:: ipv6 ``ipv6`` -------- Default: ``False`` Whether the master should listen for IPv6 connections. If this is set to True, the interface option must be adjusted too (for example: ``interface: '::'``) .. code-block:: yaml ipv6: True .. conf_master:: publish_port ``publish_port`` ---------------- Default: ``4505`` The network port to set up the publication interface. .. code-block:: yaml publish_port: 4505 .. conf_master:: master_id ``master_id`` ------------- Default: ``None`` The id to be passed in the publish job to minions. This is used for MultiSyndics to return the job to the requesting master. .. note:: This must be the same string as the syndic is configured with. .. code-block:: yaml master_id: MasterOfMaster .. conf_master:: user ``user`` -------- Default: ``root`` The user to run the Salt processes .. code-block:: yaml user: root .. conf_master:: ret_port ``enable_ssh_minions`` ---------------------- Default: ``False`` Tell the master to also use salt-ssh when running commands against minions. .. code-block:: yaml enable_ssh_minions: True .. note:: Cross-minion communication is still not possible. The Salt mine and publish.publish do not work between minion types. ``ret_port`` ------------ Default: ``4506`` The port used by the return server, this is the server used by Salt to receive execution returns and command executions. .. code-block:: yaml ret_port: 4506 .. conf_master:: pidfile ``pidfile`` ----------- Default: ``/var/run/salt-master.pid`` Specify the location of the master pidfile. .. code-block:: yaml pidfile: /var/run/salt-master.pid .. conf_master:: root_dir ``root_dir`` ------------ Default: ``/`` The system root directory to operate from, change this to make Salt run from an alternative root. .. code-block:: yaml root_dir: / .. note:: This directory is prepended to the following options: :conf_master:`pki_dir`, :conf_master:`cachedir`, :conf_master:`sock_dir`, :conf_master:`log_file`, :conf_master:`autosign_file`, :conf_master:`autoreject_file`, :conf_master:`pidfile`, :conf_master:`autosign_grains_dir`. .. conf_master:: conf_file ``conf_file`` ------------- Default: ``/etc/salt/master`` The path to the master's configuration file. .. code-block:: yaml conf_file: /etc/salt/master .. conf_master:: pki_dir ``pki_dir`` ----------- Default: ``/etc/salt/pki/master`` The directory to store the pki authentication keys. .. code-block:: yaml pki_dir: /etc/salt/pki/master .. conf_master:: extension_modules ``extension_modules`` --------------------- .. versionchanged:: 2016.3.0 The default location for this directory has been moved. Prior to this version, the location was a directory named ``extmods`` in the Salt cachedir (on most platforms, ``/var/cache/salt/extmods``). It has been moved into the master cachedir (on most platforms, ``/var/cache/salt/master/extmods``). Directory for custom modules. This directory can contain subdirectories for each of Salt's module types such as ``runners``, ``output``, ``wheel``, ``modules``, ``states``, ``returners``, ``engines``, ``utils``, etc. This path is appended to :conf_master:`root_dir`. .. code-block:: yaml extension_modules: /root/salt_extmods .. conf_master:: extmod_whitelist .. conf_master:: extmod_blacklist ``extmod_whitelist/extmod_blacklist`` ------------------------------------- .. versionadded:: 2017.7.0 By using this dictionary, the modules that are synced to the master's extmod cache using `saltutil.sync_*` can be limited. If nothing is set to a specific type, then all modules are accepted. To block all modules of a specific type, whitelist an empty list. .. code-block:: yaml extmod_whitelist: modules: - custom_module engines: - custom_engine pillars: [] extmod_blacklist: modules: - specific_module Valid options: - modules - states - grains - renderers - returners - output - proxy - runners - wheel - engines - queues - pillar - utils - sdb - cache - clouds - tops - roster - tokens .. conf_master:: module_dirs ``module_dirs`` --------------- Default: ``[]`` Like ``extension_modules``, but a list of extra directories to search for Salt modules. .. code-block:: yaml module_dirs: - /var/cache/salt/minion/extmods .. conf_master:: cachedir ``cachedir`` ------------ Default: ``/var/cache/salt/master`` The location used to store cache information, particularly the job information for executed salt commands. This directory may contain sensitive data and should be protected accordingly. .. code-block:: yaml cachedir: /var/cache/salt/master .. conf_master:: verify_env ``verify_env`` -------------- Default: ``True`` Verify and set permissions on configuration directories at startup. .. code-block:: yaml verify_env: True .. conf_master:: keep_jobs ``keep_jobs`` ------------- Default: ``24`` Set the number of hours to keep old job information. Note that setting this option to ``0`` disables the cache cleaner. .. code-block:: yaml keep_jobs: 24 .. conf_master:: gather_job_timeout ``gather_job_timeout`` ---------------------- .. versionadded:: 2014.7.0 Default: ``10`` The number of seconds to wait when the client is requesting information about running jobs. .. code-block:: yaml gather_job_timeout: 10 .. conf_master:: timeout ``timeout`` ----------- Default: ``5`` Set the default timeout for the salt command and api. .. conf_master:: loop_interval ``loop_interval`` ----------------- Default: ``60`` The loop_interval option controls the seconds for the master's maintenance process check cycle. This process updates file server backends, cleans the job cache and executes the scheduler. .. conf_master:: output ``output`` ---------- Default: ``nested`` Set the default outputter used by the salt command. .. conf_master:: outputter_dirs ``outputter_dirs`` ------------------ Default: ``[]`` A list of additional directories to search for salt outputters in. .. code-block:: yaml outputter_dirs: [] .. conf_master:: output_file ``output_file`` --------------- Default: None Set the default output file used by the salt command. Default is to output to the CLI and not to a file. Functions the same way as the "--out-file" CLI option, only sets this to a single file for all salt commands. .. code-block:: yaml output_file: /path/output/file .. conf_master:: show_timeout ``show_timeout`` ---------------- Default: ``True`` Tell the client to show minions that have timed out. .. code-block:: yaml show_timeout: True .. conf_master:: show_jid ``show_jid`` ------------ Default: ``False`` Tell the client to display the jid when a job is published. .. code-block:: yaml show_jid: False .. conf_master:: color ``color`` --------- Default: ``True`` By default output is colored, to disable colored output set the color value to False. .. code-block:: yaml color: False .. conf_master:: color_theme ``color_theme`` --------------- Default: ``""`` Specifies a path to the color theme to use for colored command line output. .. code-block:: yaml color_theme: /etc/salt/color_theme .. conf_master:: cli_summary ``cli_summary`` --------------- Default: ``False`` When set to ``True``, displays a summary of the number of minions targeted, the number of minions returned, and the number of minions that did not return. .. code-block:: yaml cli_summary: False .. conf_master:: sock_dir ``sock_dir`` ------------ Default: :file:`/var/run/salt/master` Set the location to use for creating Unix sockets for master process communication. .. code-block:: yaml sock_dir: /var/run/salt/master .. conf_master:: enable_gpu_grains ``enable_gpu_grains`` --------------------- Default: ``False`` Enable GPU hardware data for your master. Be aware that the master can take a while to start up when lspci and/or dmidecode is used to populate the grains for the master. .. code-block:: yaml enable_gpu_grains: True .. conf_master:: skip_grains ``skip_grains`` --------------------- Default: ``False`` MasterMinions should omit grains. A MasterMinion is "a minion function object for generic use on the master" that omit pillar. A RunnerClient creates a MasterMinion omitting states and renderer. Setting to True can improve master performance. .. code-block:: yaml skip_grains: True .. conf_master:: job_cache ``job_cache`` ------------- Default: ``True`` The master maintains a temporary job cache. While this is a great addition, it can be a burden on the master for larger deployments (over 5000 minions). Disabling the job cache will make previously executed jobs unavailable to the jobs system and is not generally recommended. Normally it is wise to make sure the master has access to a faster IO system or a tmpfs is mounted to the jobs dir. .. code-block:: yaml job_cache: True .. note:: Setting the ``job_cache`` to ``False`` will not cache minion returns, but the JID directory for each job is still created. The creation of the JID directories is necessary because Salt uses those directories to check for JID collisions. By setting this option to ``False``, the job cache directory, which is ``/var/cache/salt/master/jobs/`` by default, will be smaller, but the JID directories will still be present. Note that the :conf_master:`keep_jobs` option can be set to a lower value, such as ``1``, to limit the number of hours jobs are stored in the job cache. (The default is 24 hours.) Please see the :ref:`Managing the Job Cache ` documentation for more information. .. conf_master:: minion_data_cache ``minion_data_cache`` --------------------- Default: ``True`` The minion data cache is a cache of information about the minions stored on the master, this information is primarily the pillar, grains and mine data. The data is cached via the cache subsystem in the Master cachedir under the name of the minion or in a supported database. The data is used to predetermine what minions are expected to reply from executions. .. code-block:: yaml minion_data_cache: True .. conf_master:: cache ``cache`` --------- Default: ``localfs`` Cache subsystem module to use for minion data cache. .. code-block:: yaml cache: consul .. conf_master:: memcache_expire_seconds ``memcache_expire_seconds`` --------------------------- Default: ``0`` Memcache is an additional cache layer that keeps a limited amount of data fetched from the minion data cache for a limited period of time in memory that makes cache operations faster. It doesn't make much sense for the ``localfs`` cache driver but helps for more complex drivers like ``consul``. This option sets the memcache items expiration time. By default is set to ``0`` that disables the memcache. .. code-block:: yaml memcache_expire_seconds: 30 .. conf_master:: memcache_max_items ``memcache_max_items`` ---------------------- Default: ``1024`` Set memcache limit in items that are bank-key pairs. I.e the list of minion_0/data, minion_0/mine, minion_1/data contains 3 items. This value depends on the count of minions usually targeted in your environment. The best one could be found by analyzing the cache log with ``memcache_debug`` enabled. .. code-block:: yaml memcache_max_items: 1024 .. conf_master:: memcache_full_cleanup ``memcache_full_cleanup`` ------------------------- Default: ``False`` If cache storage got full, i.e. the items count exceeds the ``memcache_max_items`` value, memcache cleans up its storage. If this option set to ``False`` memcache removes the only one oldest value from its storage. If this set set to ``True`` memcache removes all the expired items and also removes the oldest one if there are no expired items. .. code-block:: yaml memcache_full_cleanup: True .. conf_master:: memcache_debug ``memcache_debug`` ------------------ Default: ``False`` Enable collecting the memcache stats and log it on `debug` log level. If enabled memcache collect information about how many ``fetch`` calls has been done and how many of them has been hit by memcache. Also it outputs the rate value that is the result of division of the first two values. This should help to choose right values for the expiration time and the cache size. .. code-block:: yaml memcache_debug: True .. conf_master:: ext_job_cache ``ext_job_cache`` ----------------- Default: ``''`` Used to specify a default returner for all minions. When this option is set, the specified returner needs to be properly configured and the minions will always default to sending returns to this returner. This will also disable the local job cache on the master. .. code-block:: yaml ext_job_cache: redis .. conf_master:: event_return ``event_return`` ---------------- .. versionadded:: 2015.5.0 Default: ``''`` Specify the returner(s) to use to log events. Each returner may have installation and configuration requirements. Read the returner's documentation. .. note:: Not all returners support event returns. Verify that a returner has an ``event_return()`` function before configuring this option with a returner. .. code-block:: yaml event_return: - syslog - splunk .. conf_master:: event_return_queue ``event_return_queue`` ---------------------- .. versionadded:: 2015.5.0 Default: ``0`` On busy systems, enabling event_returns can cause a considerable load on the storage system for returners. Events can be queued on the master and stored in a batched fashion using a single transaction for multiple events. By default, events are not queued. .. code-block:: yaml event_return_queue: 0 .. conf_master:: event_return_whitelist ``event_return_whitelist`` -------------------------- .. versionadded:: 2015.5.0 Default: ``[]`` Only return events matching tags in a whitelist. .. versionchanged:: 2016.11.0 Supports glob matching patterns. .. code-block:: yaml event_return_whitelist: - salt/master/a_tag - salt/run/*/ret .. conf_master:: event_return_blacklist ``event_return_blacklist`` -------------------------- .. versionadded:: 2015.5.0 Default: ``[]`` Store all event returns _except_ the tags in a blacklist. .. versionchanged:: 2016.11.0 Supports glob matching patterns. .. code-block:: yaml event_return_blacklist: - salt/master/not_this_tag - salt/wheel/*/ret .. conf_master:: max_event_size ``max_event_size`` ------------------ .. versionadded:: 2014.7.0 Default: ``1048576`` Passing very large events can cause the minion to consume large amounts of memory. This value tunes the maximum size of a message allowed onto the master event bus. The value is expressed in bytes. .. code-block:: yaml max_event_size: 1048576 .. conf_master:: master_job_cache ``master_job_cache`` -------------------- .. versionadded:: 2014.7.0 Default: ``local_cache`` Specify the returner to use for the job cache. The job cache will only be interacted with from the salt master and therefore does not need to be accessible from the minions. .. code-block:: yaml master_job_cache: redis .. conf_master:: job_cache_store_endtime ``job_cache_store_endtime`` --------------------------- .. versionadded:: 2015.8.0 Default: ``False`` Specify whether the Salt Master should store end times for jobs as returns come in. .. code-block:: yaml job_cache_store_endtime: False .. conf_master:: enforce_mine_cache ``enforce_mine_cache`` ---------------------- Default: False By-default when disabling the minion_data_cache mine will stop working since it is based on cached data, by enabling this option we explicitly enabling only the cache for the mine system. .. code-block:: yaml enforce_mine_cache: False .. conf_master:: max_minions ``max_minions`` --------------- Default: 0 The maximum number of minion connections allowed by the master. Use this to accommodate the number of minions per master if you have different types of hardware serving your minions. The default of ``0`` means unlimited connections. Please note that this can slow down the authentication process a bit in large setups. .. code-block:: yaml max_minions: 100 ``con_cache`` ------------- Default: False If max_minions is used in large installations, the master might experience high-load situations because of having to check the number of connected minions for every authentication. This cache provides the minion-ids of all connected minions to all MWorker-processes and greatly improves the performance of max_minions. .. code-block:: yaml con_cache: True .. conf_master:: presence_events ``presence_events`` ------------------- Default: False Causes the master to periodically look for actively connected minions. :ref:`Presence events ` are fired on the event bus on a regular interval with a list of connected minions, as well as events with lists of newly connected or disconnected minions. This is a master-only operation that does not send executions to minions. .. code-block:: yaml presence_events: False .. conf_master:: ping_on_rotate ``ping_on_rotate`` ------------------ .. versionadded:: 2014.7.0 Default: ``False`` By default, the master AES key rotates every 24 hours. The next command following a key rotation will trigger a key refresh from the minion which may result in minions which do not respond to the first command after a key refresh. To tell the master to ping all minions immediately after an AES key refresh, set ``ping_on_rotate`` to ``True``. This should mitigate the issue where a minion does not appear to initially respond after a key is rotated. Note that enabling this may cause high load on the master immediately after the key rotation event as minions reconnect. Consider this carefully if this salt master is managing a large number of minions. If disabled, it is recommended to handle this event by listening for the ``aes_key_rotate`` event with the ``key`` tag and acting appropriately. .. code-block:: yaml ping_on_rotate: False .. conf_master:: transport ``transport`` ------------- Default: ``zeromq`` Changes the underlying transport layer. ZeroMQ is the recommended transport while additional transport layers are under development. Supported values are ``zeromq`` and ``tcp`` (experimental). This setting has a significant impact on performance and should not be changed unless you know what you are doing! .. code-block:: yaml transport: zeromq .. conf_master:: transport_opts ``transport_opts`` ------------------ Default: ``{}`` (experimental) Starts multiple transports and overrides options for each transport with the provided dictionary This setting has a significant impact on performance and should not be changed unless you know what you are doing! The following example shows how to start a TCP transport alongside a ZMQ transport. .. code-block:: yaml transport_opts: tcp: publish_port: 4605 ret_port: 4606 zeromq: [] .. conf_master:: master_stats ``master_stats`` ---------------- Default: False Turning on the master stats enables runtime throughput and statistics events to be fired from the master event bus. These events will report on what functions have been run on the master and how long these runs have, on average, taken over a given period of time. .. conf_master:: master_stats_event_iter ``master_stats_event_iter`` --------------------------- Default: 60 The time in seconds to fire master_stats events. This will only fire in conjunction with receiving a request to the master, idle masters will not fire these events. .. conf_master:: sock_pool_size ``sock_pool_size`` ------------------ Default: 1 To avoid blocking waiting while writing a data to a socket, we support socket pool for Salt applications. For example, a job with a large number of target host list can cause long period blocking waiting. The option is used by ZMQ and TCP transports, and the other transport methods don't need the socket pool by definition. Most of Salt tools, including CLI, are enough to use a single bucket of socket pool. On the other hands, it is highly recommended to set the size of socket pool larger than 1 for other Salt applications, especially Salt API, which must write data to socket concurrently. .. code-block:: yaml sock_pool_size: 15 .. conf_master:: ipc_mode ``ipc_mode`` ------------ Default: ``ipc`` The ipc strategy. (i.e., sockets versus tcp, etc.) Windows platforms lack POSIX IPC and must rely on TCP based inter-process communications. ``ipc_mode`` is set to ``tcp`` by default on Windows. .. code-block:: yaml ipc_mode: ipc .. conf_master:: tcp_master_pub_port ``tcp_master_pub_port`` ----------------------- Default: ``4512`` The TCP port on which events for the master should be published if ``ipc_mode`` is TCP. .. code-block:: yaml tcp_master_pub_port: 4512 .. conf_master:: tcp_master_pull_port ``tcp_master_pull_port`` ------------------------ Default: ``4513`` The TCP port on which events for the master should be pulled if ``ipc_mode`` is TCP. .. code-block:: yaml tcp_master_pull_port: 4513 .. conf_master:: tcp_master_publish_pull ``tcp_master_publish_pull`` --------------------------- Default: ``4514`` The TCP port on which events for the master should be pulled fom and then republished onto the event bus on the master. .. code-block:: yaml tcp_master_publish_pull: 4514 .. conf_master:: tcp_master_workers ``tcp_master_workers`` ---------------------- Default: ``4515`` The TCP port for ``mworkers`` to connect to on the master. .. code-block:: yaml tcp_master_workers: 4515 .. conf_master:: auth_events ``auth_events`` --------------- .. versionadded:: 2017.7.3 Default: ``True`` Determines whether the master will fire authentication events. :ref:`Authentication events ` are fired when a minion performs an authentication check with the master. .. code-block:: yaml auth_events: True .. conf_master:: minion_data_cache_events ``minion_data_cache_events`` ---------------------------- .. versionadded:: 2017.7.3 Default: ``True`` Determines whether the master will fire minion data cache events. Minion data cache events are fired when a minion requests a minion data cache refresh. .. code-block:: yaml minion_data_cache_events: True .. conf_master:: http_connect_timeout ``http_connect_timeout`` ------------------------ .. versionadded:: 2019.2.0 Default: ``20`` HTTP connection timeout in seconds. Applied when fetching files using tornado back-end. Should be greater than overall download time. .. code-block:: yaml http_connect_timeout: 20 .. conf_master:: http_request_timeout ``http_request_timeout`` ------------------------ .. versionadded:: 2015.8.0 Default: ``3600`` HTTP request timeout in seconds. Applied when fetching files using tornado back-end. Should be greater than overall download time. .. code-block:: yaml http_request_timeout: 3600 ``use_yamlloader_old`` ---------------------- .. versionadded:: 2019.2.1 Default: ``False`` Use the pre-2019.2 YAML renderer. Uses legacy YAML rendering to support some legacy inline data structures. See the :ref:`2019.2.1 release notes ` for more details. .. code-block:: yaml use_yamlloader_old: False .. conf_master:: req_server_niceness ``req_server_niceness`` ----------------------- .. versionadded:: Sodium Default: ``None`` Process priority level of the ReqServer subprocess of the master. Supported on POSIX platforms only. .. code-block:: yaml req_server_niceness: 9 .. conf_master:: pub_server_niceness ``pub_server_niceness`` ----------------------- .. versionadded:: Sodium Default: ``None`` Process priority level of the PubServer subprocess of the master. Supported on POSIX platforms only. .. code-block:: yaml pub_server_niceness: 9 .. conf_master:: fileserver_update_niceness ``fileserver_update_niceness`` ------------------------------ .. versionadded:: Sodium Default: ``None`` Process priority level of the FileServerUpdate subprocess of the master. Supported on POSIX platforms only. .. code-block:: yaml fileserver_update_niceness: 9 .. conf_master:: maintenance_niceness ``maintenance_niceness`` ------------------------ .. versionadded:: Sodium Default: ``None`` Process priority level of the Maintenance subprocess of the master. Supported on POSIX platforms only. .. code-block:: yaml maintenance_niceness: 9 .. conf_master:: mworker_niceness ``mworker_niceness`` -------------------- .. versionadded:: Sodium Default: ``None`` Process priority level of the MWorker subprocess of the master. Supported on POSIX platforms only. .. code-block:: yaml mworker_niceness: 9 .. conf_master:: mworker_queue_niceness ``mworker_queue_niceness`` -------------------------- .. versionadded:: Sodium default: ``None`` process priority level of the MWorkerQueue subprocess of the master. supported on POSIX platforms only. .. code-block:: yaml mworker_queue_niceness: 9 .. conf_master:: event_return_niceness ``event_return_niceness`` ------------------------- .. versionadded:: Sodium default: ``None`` process priority level of the EventReturn subprocess of the master. supported on POSIX platforms only. .. code-block:: yaml event_return_niceness: 9 .. conf_master:: event_publisher_niceness ``event_publisher_niceness`` ---------------------------- .. versionadded:: Sodium default: ``none`` process priority level of the EventPublisher subprocess of the master. supported on POSIX platforms only. .. code-block:: yaml event_publisher_niceness: 9 .. conf_master:: reactor_niceness ``reactor_niceness`` -------------------- .. versionadded:: Sodium default: ``None`` process priority level of the Reactor subprocess of the master. supported on POSIX platforms only. .. code-block:: yaml reactor_niceness: 9 .. _salt-ssh-configuration: Salt-SSH Configuration ====================== .. conf_master:: roster ``roster`` --------------- Default: ``flat`` Define the default salt-ssh roster module to use .. code-block:: yaml roster: cache .. conf_master:: roster_defaults ``roster_defaults`` ------------------- .. versionadded:: 2017.7.0 Default settings which will be inherited by all rosters. .. code-block:: yaml roster_defaults: user: daniel sudo: True priv: /root/.ssh/id_rsa tty: True .. conf_master:: roster_file ``roster_file`` --------------- Default: ``/etc/salt/roster`` Pass in an alternative location for the salt-ssh :py:mod:`flat ` roster file. .. code-block:: yaml roster_file: /root/roster .. conf_master:: rosters ``rosters`` ----------- Default: ``None`` Define locations for :py:mod:`flat ` roster files so they can be chosen when using Salt API. An administrator can place roster files into these locations. Then, when calling Salt API, the :conf_master:`roster_file` parameter should contain a relative path to these locations. That is, ``roster_file=/foo/roster`` will be resolved as ``/etc/salt/roster.d/foo/roster`` etc. This feature prevents passing insecure custom rosters through the Salt API. .. code-block:: yaml rosters: - /etc/salt/roster.d - /opt/salt/some/more/rosters .. conf_master:: ssh_passwd ``ssh_passwd`` -------------- Default: ``''`` The ssh password to log in with. .. code-block:: yaml ssh_passwd: '' .. conf_master:: ssh_priv_passwd ``ssh_priv_passwd`` ------------------- Default: ``''`` Passphrase for ssh private key file. .. code-block:: yaml ssh_priv_passwd: '' .. conf_master:: ssh_port ``ssh_port`` ------------ Default: ``22`` The target system's ssh port number. .. code-block:: yaml ssh_port: 22 .. conf_master:: ssh_scan_ports ``ssh_scan_ports`` ------------------ Default: ``22`` Comma-separated list of ports to scan. .. code-block:: yaml ssh_scan_ports: 22 .. conf_master:: ssh_scan_timeout ``ssh_scan_timeout`` -------------------- Default: ``0.01`` Scanning socket timeout for salt-ssh. .. code-block:: yaml ssh_scan_timeout: 0.01 .. conf_master:: ssh_sudo ``ssh_sudo`` ------------ Default: ``False`` Boolean to run command via sudo. .. code-block:: yaml ssh_sudo: False .. conf_master:: ssh_timeout ``ssh_timeout`` --------------- Default: ``60`` Number of seconds to wait for a response when establishing an SSH connection. .. code-block:: yaml ssh_timeout: 60 .. conf_master:: ssh_user ``ssh_user`` ------------ Default: ``root`` The user to log in as. .. code-block:: yaml ssh_user: root .. conf_master:: ssh_log_file ``ssh_log_file`` ---------------- .. versionadded:: 2016.3.5 Default: ``/var/log/salt/ssh`` Specify the log file of the ``salt-ssh`` command. .. code-block:: yaml ssh_log_file: /var/log/salt/ssh .. conf_master:: ssh_minion_opts ``ssh_minion_opts`` ------------------- Default: None Pass in minion option overrides that will be inserted into the SHIM for salt-ssh calls. The local minion config is not used for salt-ssh. Can be overridden on a per-minion basis in the roster (``minion_opts``) .. code-block:: yaml ssh_minion_opts: gpg_keydir: /root/gpg .. conf_master:: ssh_use_home_key ``ssh_use_home_key`` -------------------- Default: False Set this to True to default to using ``~/.ssh/id_rsa`` for salt-ssh authentication with minions .. code-block:: yaml ssh_use_home_key: False .. conf_master:: ssh_identities_only ``ssh_identities_only`` ----------------------- Default: ``False`` Set this to ``True`` to default salt-ssh to run with ``-o IdentitiesOnly=yes``. This option is intended for situations where the ssh-agent offers many different identities and allows ssh to ignore those identities and use the only one specified in options. .. code-block:: yaml ssh_identities_only: False .. conf_master:: ssh_list_nodegroups ``ssh_list_nodegroups`` ----------------------- Default: ``{}`` List-only nodegroups for salt-ssh. Each group must be formed as either a comma-separated list, or a YAML list. This option is useful to group minions into easy-to-target groups when using salt-ssh. These groups can then be targeted with the normal -N argument to salt-ssh. .. code-block:: yaml ssh_list_nodegroups: groupA: minion1,minion2 groupB: minion1,minion3 .. conf_master:: ssh_run_pre_flight Default: False Run the ssh_pre_flight script defined in the salt-ssh roster. By default the script will only run when the thin dir does not exist on the targeted minion. This will force the script to run and not check if the thin dir exists first. .. conf_master:: thin_extra_mods ``thin_extra_mods`` ------------------- Default: None List of additional modules, needed to be included into the Salt Thin. Pass a list of importable Python modules that are typically located in the `site-packages` Python directory so they will be also always included into the Salt Thin, once generated. ``min_extra_mods`` ------------------ Default: None Identical as `thin_extra_mods`, only applied to the Salt Minimal. .. _master-security-settings: Master Security Settings ======================== .. conf_master:: open_mode ``open_mode`` ------------- Default: ``False`` Open mode is a dangerous security feature. One problem encountered with pki authentication systems is that keys can become "mixed up" and authentication begins to fail. Open mode turns off authentication and tells the master to accept all authentication. This will clean up the pki keys received from the minions. Open mode should not be turned on for general use. Open mode should only be used for a short period of time to clean up pki keys. To turn on open mode set this value to ``True``. .. code-block:: yaml open_mode: False .. conf_master:: auto_accept ``auto_accept`` --------------- Default: ``False`` Enable auto_accept. This setting will automatically accept all incoming public keys from minions. .. code-block:: yaml auto_accept: False .. conf_master:: keysize ``keysize`` ----------- Default: ``2048`` The size of key that should be generated when creating new keys. .. code-block:: yaml keysize: 2048 .. conf_master:: autosign_timeout ``autosign_timeout`` -------------------- .. versionadded:: 2014.7.0 Default: ``120`` Time in minutes that a incoming public key with a matching name found in pki_dir/minion_autosign/keyid is automatically accepted. Expired autosign keys are removed when the master checks the minion_autosign directory. This method to auto accept minions can be safer than an autosign_file because the keyid record can expire and is limited to being an exact name match. This should still be considered a less than secure option, due to the fact that trust is based on just the requesting minion id. .. conf_master:: autosign_file ``autosign_file`` ----------------- Default: ``not defined`` If the ``autosign_file`` is specified incoming keys specified in the autosign_file will be automatically accepted. Matches will be searched for first by string comparison, then by globbing, then by full-string regex matching. This should still be considered a less than secure option, due to the fact that trust is based on just the requesting minion id. .. versionchanged:: 2018.3.0 For security reasons the file must be readonly except for its owner. If :conf_master:`permissive_pki_access` is ``True`` the owning group can also have write access, but if Salt is running as ``root`` it must be a member of that group. A less strict requirement also existed in previous version. .. conf_master:: autoreject_file ``autoreject_file`` ------------------- .. versionadded:: 2014.1.0 Default: ``not defined`` Works like :conf_master:`autosign_file`, but instead allows you to specify minion IDs for which keys will automatically be rejected. Will override both membership in the :conf_master:`autosign_file` and the :conf_master:`auto_accept` setting. .. conf_master:: autosign_grains_dir ``autosign_grains_dir`` ----------------------- .. versionadded:: 2018.3.0 Default: ``not defined`` If the ``autosign_grains_dir`` is specified, incoming keys from minions with grain values that match those defined in files in the autosign_grains_dir will be accepted automatically. Grain values that should be accepted automatically can be defined by creating a file named like the corresponding grain in the autosign_grains_dir and writing the values into that file, one value per line. Lines starting with a ``#`` will be ignored. Minion must be configured to send the corresponding grains on authentication. This should still be considered a less than secure option, due to the fact that trust is based on just the requesting minion. Please see the :ref:`Autoaccept Minions from Grains ` documentation for more information. .. code-block:: yaml autosign_grains_dir: /etc/salt/autosign_grains .. conf_master:: permissive_pki_access ``permissive_pki_access`` ------------------------- Default: ``False`` Enable permissive access to the salt keys. This allows you to run the master or minion as root, but have a non-root group be given access to your pki_dir. To make the access explicit, root must belong to the group you've given access to. This is potentially quite insecure. If an autosign_file is specified, enabling permissive_pki_access will allow group access to that specific file. .. code-block:: yaml permissive_pki_access: False .. conf_master:: publisher_acl ``publisher_acl`` ----------------- Default: ``{}`` Enable user accounts on the master to execute specific modules. These modules can be expressed as regular expressions. .. code-block:: yaml publisher_acl: fred: - test.ping - pkg.* .. conf_master:: publisher_acl_blacklist ``publisher_acl_blacklist`` --------------------------- Default: ``{}`` Blacklist users or modules This example would blacklist all non sudo users, including root from running any commands. It would also blacklist any use of the "cmd" module. This is completely disabled by default. .. code-block:: yaml publisher_acl_blacklist: users: - root - '^(?!sudo_).*$' # all non sudo users modules: - cmd.* - test.echo .. conf_master:: sudo_acl ``sudo_acl`` ------------ Default: ``False`` Enforce ``publisher_acl`` and ``publisher_acl_blacklist`` when users have sudo access to the salt command. .. code-block:: yaml sudo_acl: False .. conf_master:: external_auth ``external_auth`` ----------------- Default: ``{}`` The external auth system uses the Salt auth modules to authenticate and validate users to access areas of the Salt system. .. code-block:: yaml external_auth: pam: fred: - test.* .. conf_master:: token_expire ``token_expire`` ---------------- Default: ``43200`` Time (in seconds) for a newly generated token to live. Default: 12 hours .. code-block:: yaml token_expire: 43200 .. conf_master:: token_expire_user_override ``token_expire_user_override`` ------------------------------ Default: ``False`` Allow eauth users to specify the expiry time of the tokens they generate. A boolean applies to all users or a dictionary of whitelisted eauth backends and usernames may be given: .. code-block:: yaml token_expire_user_override: pam: - fred - tom ldap: - gary .. conf_master:: keep_acl_in_token ``keep_acl_in_token`` --------------------- Default: ``False`` Set to True to enable keeping the calculated user's auth list in the token file. This is disabled by default and the auth list is calculated or requested from the eauth driver each time. .. code-block:: yaml keep_acl_in_token: False .. conf_master:: eauth_acl_module ``eauth_acl_module`` -------------------- Default: ``''`` Auth subsystem module to use to get authorized access list for a user. By default it's the same module used for external authentication. .. code-block:: yaml eauth_acl_module: django .. conf_master:: file_recv ``file_recv`` ------------- Default: ``False`` Allow minions to push files to the master. This is disabled by default, for security purposes. .. code-block:: yaml file_recv: False .. conf_master:: file_recv_max_size ``file_recv_max_size`` ---------------------- .. versionadded:: 2014.7.0 Default: ``100`` Set a hard-limit on the size of the files that can be pushed to the master. It will be interpreted as megabytes. .. code-block:: yaml file_recv_max_size: 100 .. conf_master:: master_sign_pubkey ``master_sign_pubkey`` ---------------------- Default: ``False`` Sign the master auth-replies with a cryptographic signature of the master's public key. Please see the tutorial how to use these settings in the `Multimaster-PKI with Failover Tutorial `_ .. code-block:: yaml master_sign_pubkey: True .. conf_master:: master_sign_key_name ``master_sign_key_name`` ------------------------ Default: ``master_sign`` The customizable name of the signing-key-pair without suffix. .. code-block:: yaml master_sign_key_name: .. conf_master:: master_pubkey_signature ``master_pubkey_signature`` --------------------------- Default: ``master_pubkey_signature`` The name of the file in the master's pki-directory that holds the pre-calculated signature of the master's public-key. .. code-block:: yaml master_pubkey_signature: .. conf_master:: master_use_pubkey_signature ``master_use_pubkey_signature`` ------------------------------- Default: ``False`` Instead of computing the signature for each auth-reply, use a pre-calculated signature. The :conf_master:`master_pubkey_signature` must also be set for this. .. code-block:: yaml master_use_pubkey_signature: True .. conf_master:: rotate_aes_key ``rotate_aes_key`` ------------------ Default: ``True`` Rotate the salt-masters AES-key when a minion-public is deleted with salt-key. This is a very important security-setting. Disabling it will enable deleted minions to still listen in on the messages published by the salt-master. Do not disable this unless it is absolutely clear what this does. .. code-block:: yaml rotate_aes_key: True .. conf_master:: publish_session ``publish_session`` ------------------- Default: ``86400`` The number of seconds between AES key rotations on the master. .. code-block:: yaml publish_session: Default: 86400 .. conf_master:: ssl ``ssl`` ------- .. versionadded:: 2016.11.0 Default: ``None`` TLS/SSL connection options. This could be set to a dictionary containing arguments corresponding to python ``ssl.wrap_socket`` method. For details see `Tornado `_ and `Python `_ documentation. Note: to set enum arguments values like ``cert_reqs`` and ``ssl_version`` use constant names without ssl module prefix: ``CERT_REQUIRED`` or ``PROTOCOL_SSLv23``. .. code-block:: yaml ssl: keyfile: certfile: ssl_version: PROTOCOL_TLSv1_2 .. conf_master:: preserve_minion_cache ``preserve_minion_cache`` ------------------------- Default: ``False`` By default, the master deletes its cache of minion data when the key for that minion is removed. To preserve the cache after key deletion, set ``preserve_minion_cache`` to True. WARNING: This may have security implications if compromised minions auth with a previous deleted minion ID. .. code-block:: yaml preserve_minion_cache: False .. conf_master:: allow_minion_key_revoke ``allow_minion_key_revoke`` --------------------------- Default: ``True`` Controls whether a minion can request its own key revocation. When True the master will honor the minion's request and revoke its key. When False, the master will drop the request and the minion's key will remain accepted. .. code-block:: yaml allow_minion_key_revoke: False .. conf_master:: optimization_order ``optimization_order`` ---------------------- Default: ``[0, 1, 2]`` In cases where Salt is distributed without .py files, this option determines the priority of optimization level(s) Salt's module loader should prefer. .. note:: This option is only supported on Python 3.5+. .. code-block:: yaml optimization_order: - 2 - 0 - 1 Master Large Scale Tuning Settings ================================== .. conf_master:: max_open_files ``max_open_files`` ------------------ Default: ``100000`` Each minion connecting to the master uses AT LEAST one file descriptor, the master subscription connection. If enough minions connect you might start seeing on the console(and then salt-master crashes): .. code-block:: bash Too many open files (tcp_listener.cpp:335) Aborted (core dumped) .. code-block:: yaml max_open_files: 100000 By default this value will be the one of `ulimit -Hn`, i.e., the hard limit for max open files. To set a different value than the default one, uncomment, and configure this setting. Remember that this value CANNOT be higher than the hard limit. Raising the hard limit depends on the OS and/or distribution, a good way to find the limit is to search the internet for something like this: .. code-block:: text raise max open files hard limit debian .. conf_master:: worker_threads ``worker_threads`` ------------------ Default: ``5`` The number of threads to start for receiving commands and replies from minions. If minions are stalling on replies because you have many minions, raise the worker_threads value. Worker threads should not be put below 3 when using the peer system, but can drop down to 1 worker otherwise. .. note:: When the master daemon starts, it is expected behaviour to see multiple salt-master processes, even if 'worker_threads' is set to '1'. At a minimum, a controlling process will start along with a Publisher, an EventPublisher, and a number of MWorker processes will be started. The number of MWorker processes is tuneable by the 'worker_threads' configuration value while the others are not. .. code-block:: yaml worker_threads: 5 .. conf_master:: pub_hwm ``pub_hwm`` ----------- Default: ``1000`` The zeromq high water mark on the publisher interface. .. code-block:: yaml pub_hwm: 1000 .. conf_master:: zmq_backlog ``zmq_backlog`` --------------- Default: ``1000`` The listen queue size of the ZeroMQ backlog. .. code-block:: yaml zmq_backlog: 1000 .. _master-module-management: Master Module Management ======================== .. conf_master:: runner_dirs ``runner_dirs`` --------------- Default: ``[]`` Set additional directories to search for runner modules. .. code-block:: yaml runner_dirs: - /var/lib/salt/runners .. conf_master:: utils_dirs ``utils_dirs`` --------------- .. versionadded:: 2018.3.0 Default: ``[]`` Set additional directories to search for util modules. .. code-block:: yaml utils_dirs: - /var/lib/salt/utils .. conf_master:: cython_enable ``cython_enable`` ----------------- Default: ``False`` Set to true to enable Cython modules (.pyx files) to be compiled on the fly on the Salt master. .. code-block:: yaml cython_enable: False .. _master-state-system-settings: Master State System Settings ============================ .. conf_master:: state_top ``state_top`` ------------- Default: ``top.sls`` The state system uses a "top" file to tell the minions what environment to use and what modules to use. The state_top file is defined relative to the root of the base environment. The value of "state_top" is also used for the pillar top file .. code-block:: yaml state_top: top.sls .. conf_master:: state_top_saltenv ``state_top_saltenv`` --------------------- This option has no default value. Set it to an environment name to ensure that *only* the top file from that environment is considered during a :ref:`highstate `. .. note:: Using this value does not change the merging strategy. For instance, if :conf_master:`top_file_merging_strategy` is set to ``merge``, and :conf_master:`state_top_saltenv` is set to ``foo``, then any sections for environments other than ``foo`` in the top file for the ``foo`` environment will be ignored. With :conf_master:`state_top_saltenv` set to ``base``, all states from all environments in the ``base`` top file will be applied, while all other top files are ignored. The only way to set :conf_master:`state_top_saltenv` to something other than ``base`` and not have the other environments in the targeted top file ignored, would be to set :conf_master:`top_file_merging_strategy` to ``merge_all``. .. code-block:: yaml state_top_saltenv: dev .. conf_master:: top_file_merging_strategy ``top_file_merging_strategy`` ----------------------------- .. versionchanged:: 2016.11.0 A ``merge_all`` strategy has been added. Default: ``merge`` When no specific fileserver environment (a.k.a. ``saltenv``) has been specified for a :ref:`highstate `, all environments' top files are inspected. This config option determines how the SLS targets in those top files are handled. When set to ``merge``, the ``base`` environment's top file is evaluated first, followed by the other environments' top files. The first target expression (e.g. ``'*'``) for a given environment is kept, and when the same target expression is used in a different top file evaluated later, it is ignored. Because ``base`` is evaluated first, it is authoritative. For example, if there is a target for ``'*'`` for the ``foo`` environment in both the ``base`` and ``foo`` environment's top files, the one in the ``foo`` environment would be ignored. The environments will be evaluated in no specific order (aside from ``base`` coming first). For greater control over the order in which the environments are evaluated, use :conf_master:`env_order`. Note that, aside from the ``base`` environment's top file, any sections in top files that do not match that top file's environment will be ignored. So, for example, a section for the ``qa`` environment would be ignored if it appears in the ``dev`` environment's top file. To keep use cases like this from being ignored, use the ``merge_all`` strategy. When set to ``same``, then for each environment, only that environment's top file is processed, with the others being ignored. For example, only the ``dev`` environment's top file will be processed for the ``dev`` environment, and any SLS targets defined for ``dev`` in the ``base`` environment's (or any other environment's) top file will be ignored. If an environment does not have a top file, then the top file from the :conf_master:`default_top` config parameter will be used as a fallback. When set to ``merge_all``, then all states in all environments in all top files will be applied. The order in which individual SLS files will be executed will depend on the order in which the top files were evaluated, and the environments will be evaluated in no specific order. For greater control over the order in which the environments are evaluated, use :conf_master:`env_order`. .. code-block:: yaml top_file_merging_strategy: same .. conf_master:: env_order ``env_order`` ------------- Default: ``[]`` When :conf_master:`top_file_merging_strategy` is set to ``merge``, and no environment is specified for a :ref:`highstate `, this config option allows for the order in which top files are evaluated to be explicitly defined. .. code-block:: yaml env_order: - base - dev - qa .. conf_master:: master_tops ``master_tops`` --------------- Default: ``{}`` The master_tops option replaces the external_nodes option by creating a pluggable system for the generation of external top data. The external_nodes option is deprecated by the master_tops option. To gain the capabilities of the classic external_nodes system, use the following configuration: .. code-block:: yaml master_tops: ext_nodes: .. conf_master:: renderer ``renderer`` ------------ Default: ``jinja|yaml`` The renderer to use on the minions to render the state data. .. code-block:: yaml renderer: jinja|json .. conf_master:: userdata_template ``userdata_template`` --------------------- .. versionadded:: 2016.11.4 Default: ``None`` The renderer to use for templating userdata files in salt-cloud, if the ``userdata_template`` is not set in the cloud profile. If no value is set in the cloud profile or master config file, no templating will be performed. .. code-block:: yaml userdata_template: jinja .. conf_master:: jinja_env ``jinja_env`` ------------- .. versionadded:: 2018.3.0 Default: ``{}`` jinja_env overrides the default Jinja environment options for **all templates except sls templates**. To set the options for sls templates use :conf_master:`jinja_sls_env`. .. note:: The `Jinja2 Environment documentation `_ is the official source for the default values. Not all the options listed in the jinja documentation can be overridden using :conf_master:`jinja_env` or :conf_master:`jinja_sls_env`. The default options are: .. code-block:: yaml jinja_env: block_start_string: '{%' block_end_string: '%}' variable_start_string: '{{' variable_end_string: '}}' comment_start_string: '{#' comment_end_string: '#}' line_statement_prefix: line_comment_prefix: trim_blocks: False lstrip_blocks: False newline_sequence: '\n' keep_trailing_newline: False .. conf_master:: jinja_sls_env ``jinja_sls_env`` ----------------- .. versionadded:: 2018.3.0 Default: ``{}`` jinja_sls_env sets the Jinja environment options for **sls templates**. The defaults and accepted options are exactly the same as they are for :conf_master:`jinja_env`. The default options are: .. code-block:: yaml jinja_sls_env: block_start_string: '{%' block_end_string: '%}' variable_start_string: '{{' variable_end_string: '}}' comment_start_string: '{#' comment_end_string: '#}' line_statement_prefix: line_comment_prefix: trim_blocks: False lstrip_blocks: False newline_sequence: '\n' keep_trailing_newline: False Example using line statements and line comments to increase ease of use: If your configuration options are .. code-block:: yaml jinja_sls_env: line_statement_prefix: '%' line_comment_prefix: '##' With these options jinja will interpret anything after a ``%`` at the start of a line (ignoreing whitespace) as a jinja statement and will interpret anything after a ``##`` as a comment. This allows the following more convenient syntax to be used: .. code-block:: jinja ## (this comment will not stay once rendered) # (this comment remains in the rendered template) ## ensure all the formula services are running % for service in formula_services: enable_service_{{ service }}: service.running: name: {{ service }} % endfor The following less convenient but equivalent syntax would have to be used if you had not set the line_statement and line_comment options: .. code-block:: jinja {# (this comment will not stay once rendered) #} # (this comment remains in the rendered template) {# ensure all the formula services are running #} {% for service in formula_services %} enable_service_{{ service }}: service.running: name: {{ service }} {% endfor %} .. conf_master:: jinja_trim_blocks ``jinja_trim_blocks`` --------------------- .. deprecated:: 2018.3.0 Replaced by :conf_master:`jinja_env` and :conf_master:`jinja_sls_env` .. versionadded:: 2014.1.0 Default: ``False`` If this is set to ``True``, the first newline after a Jinja block is removed (block, not variable tag!). Defaults to ``False`` and corresponds to the Jinja environment init variable ``trim_blocks``. .. code-block:: yaml jinja_trim_blocks: False .. conf_master:: jinja_lstrip_blocks ``jinja_lstrip_blocks`` ----------------------- .. deprecated:: 2018.3.0 Replaced by :conf_master:`jinja_env` and :conf_master:`jinja_sls_env` .. versionadded:: 2014.1.0 Default: ``False`` If this is set to ``True``, leading spaces and tabs are stripped from the start of a line to a block. Defaults to ``False`` and corresponds to the Jinja environment init variable ``lstrip_blocks``. .. code-block:: yaml jinja_lstrip_blocks: False .. conf_master:: failhard ``failhard`` ------------ Default: ``False`` Set the global failhard flag. This informs all states to stop running states at the moment a single state fails. .. code-block:: yaml failhard: False .. conf_master:: state_verbose ``state_verbose`` ----------------- Default: ``True`` Controls the verbosity of state runs. By default, the results of all states are returned, but setting this value to ``False`` will cause salt to only display output for states that failed or states that have changes. .. code-block:: yaml state_verbose: False .. conf_master:: state_output ``state_output`` ---------------- Default: ``full`` The state_output setting controls which results will be output full multi line: * ``full``, ``terse`` - each state will be full/terse * ``mixed`` - only states with errors will be full * ``changes`` - states with changes and errors will be full ``full_id``, ``mixed_id``, ``changes_id`` and ``terse_id`` are also allowed; when set, the state ID will be used as name in the output. .. code-block:: yaml state_output: full .. conf_master:: state_output_diff ``state_output_diff`` --------------------- Default: ``False`` The state_output_diff setting changes whether or not the output from successful states is returned. Useful when even the terse output of these states is cluttering the logs. Set it to True to ignore them. .. code-block:: yaml state_output_diff: False .. conf_master:: state_aggregate ``state_aggregate`` ------------------- Default: ``False`` Automatically aggregate all states that have support for mod_aggregate by setting to ``True``. Or pass a list of state module names to automatically aggregate just those types. .. code-block:: yaml state_aggregate: - pkg .. code-block:: yaml state_aggregate: True .. conf_master:: state_events ``state_events`` ---------------- Default: ``False`` Send progress events as each function in a state run completes execution by setting to ``True``. Progress events are in the format ``salt/job//prog//``. .. code-block:: yaml state_events: True .. conf_master:: yaml_utf8 ``yaml_utf8`` ------------- Default: ``False`` Enable extra routines for YAML renderer used states containing UTF characters. .. code-block:: yaml yaml_utf8: False ``runner_returns`` ------------------ Default: ``False`` If set to ``True``, runner jobs will be saved to job cache (defined by :conf_master:`master_job_cache`). .. code-block:: yaml runner_returns: True .. _master-file-server-settings: Master File Server Settings =========================== .. conf_master:: fileserver_backend ``fileserver_backend`` ---------------------- Default: ``['roots']`` Salt supports a modular fileserver backend system, this system allows the salt master to link directly to third party systems to gather and manage the files available to minions. Multiple backends can be configured and will be searched for the requested file in the order in which they are defined here. The default setting only enables the standard backend ``roots``, which is configured using the :conf_master:`file_roots` option. Example: .. code-block:: yaml fileserver_backend: - roots - gitfs .. note:: For masterless Salt, this parameter must be specified in the minion config file. .. conf_master:: fileserver_followsymlinks ``fileserver_followsymlinks`` ----------------------------- .. versionadded:: 2014.1.0 Default: ``True`` By default, the file_server follows symlinks when walking the filesystem tree. Currently this only applies to the default roots fileserver_backend. .. code-block:: yaml fileserver_followsymlinks: True .. conf_master:: fileserver_ignoresymlinks ``fileserver_ignoresymlinks`` ----------------------------- .. versionadded:: 2014.1.0 Default: ``False`` If you do not want symlinks to be treated as the files they are pointing to, set ``fileserver_ignoresymlinks`` to ``True``. By default this is set to False. When set to ``True``, any detected symlink while listing files on the Master will not be returned to the Minion. .. code-block:: yaml fileserver_ignoresymlinks: False .. conf_master:: fileserver_limit_traversal ``fileserver_limit_traversal`` ------------------------------ .. versionadded:: 2014.1.0 .. deprecated:: 2018.3.4 This option is now ignored. Firstly, it only traversed :conf_master:`file_roots`, which means it did not work for the other fileserver backends. Secondly, since this option was added we have added caching to the code that traverses the file_roots (and gitfs, etc.), which greatly reduces the amount of traversal that is done. Default: ``False`` By default, the Salt fileserver recurses fully into all defined environments to attempt to find files. To limit this behavior so that the fileserver only traverses directories with SLS files and special Salt directories like _modules, set ``fileserver_limit_traversal`` to ``True``. This might be useful for installations where a file root has a very large number of files and performance is impacted. .. code-block:: yaml fileserver_limit_traversal: False .. conf_master:: fileserver_list_cache_time ``fileserver_list_cache_time`` ------------------------------ .. versionadded:: 2014.1.0 .. versionchanged:: 2016.11.0 The default was changed from ``30`` seconds to ``20``. Default: ``20`` Salt caches the list of files/symlinks/directories for each fileserver backend and environment as they are requested, to guard against a performance bottleneck at scale when many minions all ask the fileserver which files are available simultaneously. This configuration parameter allows for the max age of that cache to be altered. Set this value to ``0`` to disable use of this cache altogether, but keep in mind that this may increase the CPU load on the master when running a highstate on a large number of minions. .. note:: Rather than altering this configuration parameter, it may be advisable to use the :mod:`fileserver.clear_file_list_cache ` runner to clear these caches. .. code-block:: yaml fileserver_list_cache_time: 5 .. conf_master:: fileserver_verify_config ``fileserver_verify_config`` ---------------------------- .. versionadded:: 2017.7.0 Default: ``True`` By default, as the master starts it performs some sanity checks on the configured fileserver backends. If any of these sanity checks fail (such as when an invalid configuration is used), the master daemon will abort. To skip these sanity checks, set this option to ``False``. .. code-block:: yaml fileserver_verify_config: False .. conf_master:: hash_type ``hash_type`` ------------- Default: ``sha256`` The hash_type is the hash to use when discovering the hash of a file on the master server. The default is sha256, but md5, sha1, sha224, sha384, and sha512 are also supported. .. code-block:: yaml hash_type: sha256 .. conf_master:: file_buffer_size ``file_buffer_size`` -------------------- Default: ``1048576`` The buffer size in the file server in bytes. .. code-block:: yaml file_buffer_size: 1048576 .. conf_master:: file_ignore_regex ``file_ignore_regex`` --------------------- Default: ``''`` A regular expression (or a list of expressions) that will be matched against the file path before syncing the modules and states to the minions. This includes files affected by the file.recurse state. For example, if you manage your custom modules and states in subversion and don't want all the '.svn' folders and content synced to your minions, you could set this to '/\.svn($|/)'. By default nothing is ignored. .. code-block:: yaml file_ignore_regex: - '/\.svn($|/)' - '/\.git($|/)' .. conf_master:: file_ignore_glob ``file_ignore_glob`` -------------------- Default ``''`` A file glob (or list of file globs) that will be matched against the file path before syncing the modules and states to the minions. This is similar to file_ignore_regex above, but works on globs instead of regex. By default nothing is ignored. .. code-block:: yaml file_ignore_glob: - '\*.pyc' - '\*/somefolder/\*.bak' - '\*.swp' .. note:: Vim's .swp files are a common cause of Unicode errors in :py:func:`file.recurse ` states which use templating. Unless there is a good reason to distribute them via the fileserver, it is good practice to include ``'\*.swp'`` in the :conf_master:`file_ignore_glob`. .. conf_master:: master_roots ``master_roots`` ---------------- Default: ``''`` A master-only copy of the :conf_master:`file_roots` dictionary, used by the state compiler. Example: .. code-block:: yaml master_roots: base: - /srv/salt-master roots: Master's Local File Server --------------------------------- .. conf_master:: file_roots ``file_roots`` ************** Default: .. code-block:: yaml base: - /srv/salt Salt runs a lightweight file server written in ZeroMQ to deliver files to minions. This file server is built into the master daemon and does not require a dedicated port. The file server works on environments passed to the master. Each environment can have multiple root directories. The subdirectories in the multiple file roots cannot match, otherwise the downloaded files will not be able to be reliably ensured. A base environment is required to house the top file. As of 2018.3.5 and 2019.2.1, it is possible to have `__env__` as a catch-all environment. Example: .. code-block:: yaml file_roots: base: - /srv/salt dev: - /srv/salt/dev/services - /srv/salt/dev/states prod: - /srv/salt/prod/services - /srv/salt/prod/states __env__: - /srv/salt/default .. note:: For masterless Salt, this parameter must be specified in the minion config file. .. conf_master:: roots_update_interval ``roots_update_interval`` ************************* .. versionadded:: 2018.3.0 Default: ``60`` This option defines the update interval (in seconds) for :conf_master:`file_roots`. .. note:: Since ``file_roots`` consists of files local to the minion, the update process for this fileserver backend just reaps the cache for this backend. .. code-block:: yaml roots_update_interval: 120 gitfs: Git Remote File Server Backend ------------------------------------- .. conf_master:: gitfs_remotes ``gitfs_remotes`` ***************** Default: ``[]`` When using the ``git`` fileserver backend at least one git remote needs to be defined. The user running the salt master will need read access to the repo. The repos will be searched in order to find the file requested by a client and the first repo to have the file will return it. Branches and tags are translated into salt environments. .. code-block:: yaml gitfs_remotes: - git://github.com/saltstack/salt-states.git - file:///var/git/saltmaster .. note:: ``file://`` repos will be treated as a remote and copied into the master's gitfs cache, so only the *local* refs for those repos will be exposed as fileserver environments. As of 2014.7.0, it is possible to have per-repo versions of several of the gitfs configuration parameters. For more information, see the :ref:`GitFS Walkthrough `. .. conf_master:: gitfs_provider ``gitfs_provider`` ****************** .. versionadded:: 2014.7.0 Optional parameter used to specify the provider to be used for gitfs. More information can be found in the :ref:`GitFS Walkthrough `. Must be either ``pygit2`` or ``gitpython``. If unset, then each will be tried in that same order, and the first one with a compatible version installed will be the provider that is used. .. code-block:: yaml gitfs_provider: gitpython .. conf_master:: gitfs_ssl_verify ``gitfs_ssl_verify`` ******************** Default: ``True`` Specifies whether or not to ignore SSL certificate errors when fetching from the repositories configured in :conf_master:`gitfs_remotes`. The ``False`` setting is useful if you're using a git repo that uses a self-signed certificate. However, keep in mind that setting this to anything other ``True`` is a considered insecure, and using an SSH-based transport (if available) may be a better option. .. code-block:: yaml gitfs_ssl_verify: False .. note:: pygit2 only supports disabling SSL verification in versions 0.23.2 and newer. .. versionchanged:: 2015.8.0 This option can now be configured on individual repositories as well. See :ref:`here ` for more info. .. versionchanged:: 2016.11.0 The default config value changed from ``False`` to ``True``. .. conf_master:: gitfs_mountpoint ``gitfs_mountpoint`` ******************** .. versionadded:: 2014.7.0 Default: ``''`` Specifies a path on the salt fileserver which will be prepended to all files served by gitfs. This option can be used in conjunction with :conf_master:`gitfs_root`. It can also be configured for an individual repository, see :ref:`here ` for more info. .. code-block:: yaml gitfs_mountpoint: salt://foo/bar .. note:: The ``salt://`` protocol designation can be left off (in other words, ``foo/bar`` and ``salt://foo/bar`` are equivalent). Assuming a file ``baz.sh`` in the root of a gitfs remote, and the above example mountpoint, this file would be served up via ``salt://foo/bar/baz.sh``. .. conf_master:: gitfs_root ``gitfs_root`` ************** Default: ``''`` Relative path to a subdirectory within the repository from which Salt should begin to serve files. This is useful when there are files in the repository that should not be available to the Salt fileserver. Can be used in conjunction with :conf_master:`gitfs_mountpoint`. If used, then from Salt's perspective the directories above the one specified will be ignored and the relative path will (for the purposes of gitfs) be considered as the root of the repo. .. code-block:: yaml gitfs_root: somefolder/otherfolder .. versionchanged:: 2014.7.0 This option can now be configured on individual repositories as well. See :ref:`here ` for more info. .. conf_master:: gitfs_base ``gitfs_base`` ************** Default: ``master`` Defines which branch/tag should be used as the ``base`` environment. .. code-block:: yaml gitfs_base: salt .. versionchanged:: 2014.7.0 This option can now be configured on individual repositories as well. See :ref:`here ` for more info. .. conf_master:: gitfs_saltenv ``gitfs_saltenv`` ***************** .. versionadded:: 2016.11.0 Default: ``[]`` Global settings for :ref:`per-saltenv configuration parameters `. Though per-saltenv configuration parameters are typically one-off changes specific to a single gitfs remote, and thus more often configured on a per-remote basis, this parameter can be used to specify per-saltenv changes which should apply to all remotes. For example, the below configuration will map the ``develop`` branch to the ``dev`` saltenv for all gitfs remotes. .. code-block:: yaml gitfs_saltenv: - dev: - ref: develop .. conf_master:: gitfs_disable_saltenv_mapping ``gitfs_disable_saltenv_mapping`` ********************************* .. versionadded:: 2018.3.0 Default: ``False`` When set to ``True``, all saltenv mapping logic is disregarded (aside from which branch/tag is mapped to the ``base`` saltenv). To use any other environments, they must then be defined using :ref:`per-saltenv configuration parameters `. .. code-block:: yaml gitfs_disable_saltenv_mapping: True .. note:: This is is a global configuration option, see :ref:`here ` for examples of configuring it for individual repositories. .. conf_master:: gitfs_ref_types ``gitfs_ref_types`` ******************* .. versionadded:: 2018.3.0 Default: ``['branch', 'tag', 'sha']`` This option defines what types of refs are mapped to fileserver environments (i.e. saltenvs). It also sets the order of preference when there are ambiguously-named refs (i.e. when a branch and tag both have the same name). The below example disables mapping of both tags and SHAs, so that only branches are mapped as saltenvs: .. code-block:: yaml gitfs_ref_types: - branch .. note:: This is is a global configuration option, see :ref:`here ` for examples of configuring it for individual repositories. .. note:: ``sha`` is special in that it will not show up when listing saltenvs (e.g. with the :py:func:`fileserver.envs ` runner), but works within states and with :py:func:`cp.cache_file ` to retrieve a file from a specific git SHA. .. conf_master:: gitfs_saltenv_whitelist ``gitfs_saltenv_whitelist`` *************************** .. versionadded:: 2014.7.0 .. versionchanged:: 2018.3.0 Renamed from ``gitfs_env_whitelist`` to ``gitfs_saltenv_whitelist`` Default: ``[]`` Used to restrict which environments are made available.

More information can be found in the :ref:`GitFS Walkthrough `. .. code-block:: yaml gitfs_saltenv_blacklist: - base - v1.* - 'mybranch\d+' .. conf_master:: gitfs_global_lock ``gitfs_global_lock`` ********************* .. versionadded:: 2015.8.9 Default: ``True`` When set to ``False``, if there is an update lock for a gitfs remote and the pid written to it is not running on the master, the lock file will be automatically cleared and a new lock will be obtained. When set to ``True``, Salt will simply log a warning when there is an update lock present. On single-master deployments, disabling this option can help automatically deal with instances where the master was shutdown/restarted during the middle of a gitfs update, leaving a update lock in place. However, on multi-master deployments with the gitfs cachedir shared via `GlusterFS`__, nfs, or another network filesystem, it is strongly recommended not to disable this option as doing so will cause lock files to be removed if they were created by a different master. .. code-block:: yaml # Disable global lock gitfs_global_lock: False .. __: http://www.gluster.org/ .. conf_master:: gitfs_update_interval ``gitfs_update_interval`` ************************* .. versionadded:: 2018.3.0 Default: ``60`` This option defines the default update interval (in seconds) for gitfs remotes. The update interval can also be set for a single repository via a :ref:`per-remote config option ` .. code-block:: yaml gitfs_update_interval: 120 GitFS Authentication Options **************************** These parameters only currently apply to the pygit2 gitfs provider. Examples of how to use these can be found in the :ref:`GitFS Walkthrough `. .. conf_master:: gitfs_user ``gitfs_user`` ~~~~~~~~~~~~~~ .. versionadded:: 2014.7.0 Default: ``''`` Along with :conf_master:`gitfs_password`, is used to authenticate to HTTPS remotes. .. code-block:: yaml gitfs_user: git .. note:: This is is a global configuration option, see :ref:`here ` for examples of configuring it for individual repositories. .. conf_master:: gitfs_password ``gitfs_password`` ~~~~~~~~~~~~~~~~~~ .. versionadded:: 2014.7.0 Default: ``''`` Along with :conf_master:`gitfs_user`, is used to authenticate to HTTPS remotes. This parameter is not required if the repository does not use authentication. .. code-block:: yaml gitfs_password: mypassword .. note:: This is is a global configuration option, see :ref:`here ` for examples of configuring it for individual repositories. .. conf_master:: gitfs_insecure_auth ``gitfs_insecure_auth`` ~~~~~~~~~~~~~~~~~~~~~~~ .. versionadded:: 2014.7.0 Default: ``False`` By default, Salt will not authenticate to an HTTP (non-HTTPS) remote. This parameter enables authentication over HTTP. **Enable this at your own risk.** .. code-block:: yaml gitfs_insecure_auth: True .. note:: This is is a global configuration option, see :ref:`here ` for examples of configuring it for individual repositories. .. conf_master:: gitfs_pubkey ``gitfs_pubkey`` ~~~~~~~~~~~~~~~~ .. versionadded:: 2014.7.0 Default: ``''`` Along with :conf_master:`gitfs_privkey` (and optionally :conf_master:`gitfs_passphrase`), is used to authenticate to SSH remotes. Required for SSH remotes. .. code-block:: yaml gitfs_pubkey: /path/to/key.pub .. note:: This is is a global configuration option, see :ref:`here ` for examples of configuring it for individual repositories. .. conf_master:: gitfs_privkey ``gitfs_privkey`` ~~~~~~~~~~~~~~~~~ .. versionadded:: 2014.7.0 Default: ``''`` Along with :conf_master:`gitfs_pubkey` (and optionally :conf_master:`gitfs_passphrase`), is used to authenticate to SSH remotes.

This parameter can be used to override the default and specify alternate refspecs to be fetched. More information on how this feature works can be found in the :ref:`GitFS Walkthrough `. .. code-block:: yaml gitfs_refspecs: - '+refs/heads/*:refs/remotes/origin/*' - '+refs/tags/*:refs/tags/*' - '+refs/pull/*/head:refs/remotes/origin/pr/*' - '+refs/pull/*/merge:refs/remotes/origin/merge/*' hgfs: Mercurial Remote File Server Backend ------------------------------------------ .. conf_master:: hgfs_remotes ``hgfs_remotes`` **************** .. versionadded:: 0.17.0 Default: ``[]`` When using the ``hg`` fileserver backend at least one mercurial remote needs to be defined. The user running the salt master will need read access to the repo. The repos will be searched in order to find the file requested by a client and the first repo to have the file will return it. Branches and/or bookmarks are translated into salt environments, as defined by the :conf_master:`hgfs_branch_method` parameter. .. code-block:: yaml hgfs_remotes: - https://username@bitbucket.org/username/reponame .. note:: As of 2014.7.0, it is possible to have per-repo versions of the :conf_master:`hgfs_root`, :conf_master:`hgfs_mountpoint`, :conf_master:`hgfs_base`, and :conf_master:`hgfs_branch_method` parameters. For example: .. code-block:: yaml hgfs_remotes: - https://username@bitbucket.org/username/repo1 - base: saltstates - https://username@bitbucket.org/username/repo2: - root: salt - mountpoint: salt://foo/bar/baz - https://username@bitbucket.org/username/repo3: - root: salt/states - branch_method: mixed .. conf_master:: hgfs_branch_method ``hgfs_branch_method`` ********************** .. versionadded:: 0.17.0 Default: ``branches`` Defines the objects that will be used as fileserver environments. * ``branches`` - Only branches and tags will be used * ``bookmarks`` - Only bookmarks and tags will be used * ``mixed`` - Branches, bookmarks, and tags will be used .. code-block:: yaml hgfs_branch_method: mixed .. note:: Starting in version 2014.1.0, the value of the :conf_master:`hgfs_base` parameter defines which branch is used as the ``base`` environment, allowing for a ``base`` environment to be used with an :conf_master:`hgfs_branch_method` of ``bookmarks``. Prior to this release, the ``default`` branch will be used as the ``base`` environment. .. conf_master:: hgfs_mountpoint ``hgfs_mountpoint`` ******************* .. versionadded:: 2014.7.0 Default: ``''`` Specifies a path on the salt fileserver which will be prepended to all files served by hgfs.

This configuration is the same as :conf_master:`file_roots`: As of 2017.7.5 and 2018.3.1, it is possible to have `__env__` as a catch-all environment. Example: .. code-block:: yaml pillar_roots: base: - /srv/pillar dev: - /srv/pillar/dev prod: - /srv/pillar/prod __env__: - /srv/pillar/others .. conf_master:: on_demand_ext_pillar ``on_demand_ext_pillar`` ------------------------ .. versionadded:: 2016.3.6,2016.11.3,2017.7.0 Default: ``['libvirt', 'virtkey']`` The external pillars permitted to be used on-demand using :py:func:`pillar.ext `. .. code-block:: yaml on_demand_ext_pillar: - libvirt - virtkey - git .. warning:: This will allow minions to request specific pillar data via :py:func:`pillar.ext `, and may be considered a security risk. However, pillar data generated in this way will not affect the :ref:`in-memory pillar data `, so this risk is limited to instances in which states/modules/etc. (built-in or custom) rely upon pillar data generated by :py:func:`pillar.ext `. .. conf_master:: decrypt_pillar ``decrypt_pillar`` ------------------ .. versionadded:: 2017.7.0 Default: ``[]`` A list of paths to be recursively decrypted during pillar compilation. .. code-block:: yaml decrypt_pillar: - 'foo:bar': gpg - 'lorem:ipsum:dolor' Entries in this list can be formatted either as a simple string, or as a key/value pair, with the key being the pillar location, and the value being the renderer to use for pillar decryption. If the former is used, the renderer specified by :conf_master:`decrypt_pillar_default` will be used. .. conf_master:: decrypt_pillar_delimiter ``decrypt_pillar_delimiter`` ---------------------------- .. versionadded:: 2017.7.0 Default: ``:`` The delimiter used to distinguish nested data structures in the :conf_master:`decrypt_pillar` option. .. code-block:: yaml decrypt_pillar_delimiter: '|' decrypt_pillar: - 'foo|bar': gpg - 'lorem|ipsum|dolor' .. conf_master:: decrypt_pillar_default ``decrypt_pillar_default`` -------------------------- .. versionadded:: 2017.7.0 Default: ``gpg`` The default renderer used for decryption, if one is not specified for a given pillar key in :conf_master:`decrypt_pillar`. .. code-block:: yaml decrypt_pillar_default: my_custom_renderer .. conf_master:: decrypt_pillar_renderers ``decrypt_pillar_renderers`` ---------------------------- .. versionadded:: 2017.7.0 Default: ``['gpg']`` List of renderers which are permitted to be used for pillar decryption. .. code-block:: yaml decrypt_pillar_renderers: - gpg - my_custom_renderer .. conf_master:: pillar_opts ``pillar_opts`` --------------- Default: ``False`` The ``pillar_opts`` option adds the master configuration file data to a dict in the pillar called ``master``. This can be used to set simple configurations in the master config file that can then be used on minions. Note that setting this option to ``True`` means the master config file will be included in all minion's pillars. While this makes global configuration of services and systems easy, it may not be desired if sensitive data is stored in the master configuration. .. code-block:: yaml pillar_opts: False .. conf_master:: pillar_safe_render_error ``pillar_safe_render_error`` ---------------------------- Default: ``True`` The pillar_safe_render_error option prevents the master from passing pillar render errors to the minion. This is set on by default because the error could contain templating data which would give that minion information it shouldn't have, like a password! When set ``True`` the error message will only show: .. code-block:: shell Rendering SLS 'my.sls' failed. Please see master log for details. .. code-block:: yaml pillar_safe_render_error: True .. _master-configuration-ext-pillar: .. conf_master:: ext_pillar ``ext_pillar`` -------------- The ext_pillar option allows for any number of external pillar interfaces to be called when populating pillar data. The configuration is based on ext_pillar functions. The available ext_pillar functions can be found herein: :blob:`salt/pillar` By default, the ext_pillar interface is not configured to run. Default: ``[]`` .. code-block:: yaml ext_pillar: - hiera: /etc/hiera.yaml - cmd_yaml: cat /etc/salt/yaml - reclass: inventory_base_uri: /etc/reclass There are additional details at :ref:`salt-pillars` .. conf_master:: ext_pillar_first ``ext_pillar_first`` -------------------- .. versionadded:: 2015.5.0 Default: ``False`` This option allows for external pillar sources to be evaluated before :conf_master:`pillar_roots`. External pillar data is evaluated separately from :conf_master:`pillar_roots` pillar data, and then both sets of pillar data are merged into a single pillar dictionary, so the value of this config option will have an impact on which key "wins" when there is one of the same name in both the external pillar data and :conf_master:`pillar_roots` pillar data. By setting this option to ``True``, ext_pillar keys will be overridden by :conf_master:`pillar_roots`, while leaving it as ``False`` will allow ext_pillar keys to override those from :conf_master:`pillar_roots`. .. note:: For a while, this config option did not work as specified above, because of a bug in Pillar compilation. This bug has been resolved in version 2016.3.4 and later. .. code-block:: yaml ext_pillar_first: False .. conf_master:: pillarenv_from_saltenv ``pillarenv_from_saltenv`` -------------------------- Default: ``False`` When set to ``True``, the :conf_master:`pillarenv` value will assume the value of the effective saltenv when running states. This essentially makes ``salt-run pillar.show_pillar saltenv=dev`` equivalent to ``salt-run pillar.show_pillar saltenv=dev pillarenv=dev``. If :conf_master:`pillarenv` is set on the CLI, it will override this option. .. code-block:: yaml pillarenv_from_saltenv: True .. note:: For salt remote execution commands this option should be set in the Minion configuration instead. .. conf_master:: pillar_raise_on_missing ``pillar_raise_on_missing`` --------------------------- .. versionadded:: 2015.5.0 Default: ``False`` Set this option to ``True`` to force a ``KeyError`` to be raised whenever an attempt to retrieve a named value from pillar fails. When this option is set to ``False``, the failed attempt returns an empty string. .. _git-pillar-config-opts: Git External Pillar (git_pillar) Configuration Options ------------------------------------------------------ .. conf_master:: git_pillar_provider ``git_pillar_provider`` *********************** .. versionadded:: 2015.8.0 Specify the provider to be used for git_pillar. Must be either ``pygit2`` or ``gitpython``. If unset, then both will be tried in that same order, and the first one with a compatible version installed will be the provider that is used. .. code-block:: yaml git_pillar_provider: gitpython .. conf_master:: git_pillar_base ``git_pillar_base`` ******************* .. versionadded:: 2015.8.0 Default: ``master`` If the desired branch matches this value, and the environment is omitted from the git_pillar configuration, then the environment for that git_pillar remote will be ``base``. For example, in the configuration below, the ``foo`` branch/tag would be assigned to the ``base`` environment, while ``bar`` would be mapped to the ``bar`` environment. .. code-block:: yaml git_pillar_base: foo ext_pillar: - git: - foo https://mygitserver/git-pillar.git - bar https://mygitserver/git-pillar.git .. conf_master:: git_pillar_branch ``git_pillar_branch`` ********************* .. versionadded:: 2015.8.0 Default: ``master`` If the branch is omitted from a git_pillar remote, then this branch will be used instead. For example, in the configuration below, the first two remotes would use the ``pillardata`` branch/tag, while the third would use the ``foo`` branch/tag. .. code-block:: yaml git_pillar_branch: pillardata ext_pillar: - git: - https://mygitserver/pillar1.git - https://mygitserver/pillar2.git: - root: pillar - foo https://mygitserver/pillar3.git .. conf_master:: git_pillar_env ``git_pillar_env`` ****************** .. versionadded:: 2015.8.0 Default: ``''`` (unset) Environment to use for git_pillar remotes. This is normally derived from the branch/tag (or from a per-remote ``env`` parameter), but if set this will override the process of deriving the env from the branch/tag name. For example, in the configuration below the ``foo`` branch would be assigned to the ``base`` environment, while the ``bar`` branch would need to explicitly have ``bar`` configured as its environment to keep it from also being mapped to the ``base`` environment. .. code-block:: yaml git_pillar_env: base ext_pillar: - git: - foo https://mygitserver/git-pillar.git - bar https://mygitserver/git-pillar.git: - env: bar For this reason, this option is recommended to be left unset, unless the use case calls for all (or almost all) of the git_pillar remotes to use the same environment irrespective of the branch/tag being used. .. conf_master:: git_pillar_root ``git_pillar_root`` ******************* .. versionadded:: 2015.8.0 Default: ``''`` Path relative to the root of the repository where the git_pillar top file and SLS files are located. In the below configuration, the pillar top file and SLS files would be looked for in a subdirectory called ``pillar``. .. code-block:: yaml git_pillar_root: pillar ext_pillar: - git: - master https://mygitserver/pillar1.git - master https://mygitserver/pillar2.git .. note:: This is a global option. If only one or two repos need to have their files sourced from a subdirectory, then :conf_master:`git_pillar_root` can be omitted and the root can be specified on a per-remote basis, like so: .. code-block:: yaml ext_pillar: - git: - master https://mygitserver/pillar1.git - master https://mygitserver/pillar2.git: - root: pillar In this example, for the first remote the top file and SLS files would be looked for in the root of the repository, while in the second remote the pillar data would be retrieved from the ``pillar`` subdirectory. .. conf_master:: git_pillar_ssl_verify ``git_pillar_ssl_verify`` ************************* .. versionadded:: 2015.8.0 .. versionchanged:: 2016.11.0 Default: ``False`` Specifies whether or not to ignore SSL certificate errors when contacting the remote repository. The ``False`` setting is useful if you're using a git repo that uses a self-signed certificate. However, keep in mind that setting this to anything other ``True`` is a considered insecure, and using an SSH-based transport (if available) may be a better option. In the 2016.11.0 release, the default config value changed from ``False`` to ``True``. .. code-block:: yaml git_pillar_ssl_verify: True .. note:: pygit2 only supports disabling SSL verification in versions 0.23.2 and newer. .. conf_master:: git_pillar_global_lock ``git_pillar_global_lock`` ************************** .. versionadded:: 2015.8.9 Default: ``True`` When set to ``False``, if there is an update/checkout lock for a git_pillar remote and the pid written to it is not running on the master, the lock file will be automatically cleared and a new lock will be obtained. When set to ``True``, Salt will simply log a warning when there is an lock present. On single-master deployments, disabling this option can help automatically deal with instances where the master was shutdown/restarted during the middle of a git_pillar update/checkout, leaving a lock in place. However, on multi-master deployments with the git_pillar cachedir shared via `GlusterFS`__, nfs, or another network filesystem, it is strongly recommended not to disable this option as doing so will cause lock files to be removed if they were created by a different master. .. code-block:: yaml # Disable global lock git_pillar_global_lock: False .. __: http://www.gluster.org/ .. conf_master:: git_pillar_includes ``git_pillar_includes`` *********************** .. versionadded:: 2017.7.0 Default: ``True`` Normally, when processing :ref:`git_pillar remotes `, if more than one repo under the same ``git`` section in the ``ext_pillar`` configuration refers to the same pillar environment, then each repo in a given environment will have access to the other repos' files to be referenced in their top files. However, it may be desirable to disable this behavior. If so, set this value to ``False``. For a more detailed examination of how includes work, see :ref:`this explanation ` from the git_pillar documentation. .. code-block:: yaml git_pillar_includes: False ``git_pillar_update_interval`` ****************************** .. versionadded:: 3000 Default: ``60`` This option defines the default update interval (in seconds) for git_pillar remotes. The update is handled within the global loop, hence ``git_pillar_update_interval`` should be a multiple of ``loop_interval``. .. code-block:: yaml git_pillar_update_interval: 120 .. _git-ext-pillar-auth-opts: Git External Pillar Authentication Options ****************************************** These parameters only currently apply to the ``pygit2`` :conf_master:`git_pillar_provider`. Authentication works the same as it does in gitfs, as outlined in the :ref:`GitFS Walkthrough `, though the global configuration options are named differently to reflect that they are for git_pillar instead of gitfs. .. conf_master:: git_pillar_user ``git_pillar_user`` ~~~~~~~~~~~~~~~~~~~ .. versionadded:: 2015.8.0 Default: ``''`` Along with :conf_master:`git_pillar_password`, is used to authenticate to HTTPS remotes. .. code-block:: yaml git_pillar_user: git .. conf_master:: git_pillar_password ``git_pillar_password`` ~~~~~~~~~~~~~~~~~~~~~~~ .. versionadded:: 2015.8.0 Default: ``''`` Along with :conf_master:`git_pillar_user`, is used to authenticate to HTTPS remotes. This parameter is not required if the repository does not use authentication. .. code-block:: yaml git_pillar_password: mypassword .. conf_master:: git_pillar_insecure_auth ``git_pillar_insecure_auth`` ~~~~~~~~~~~~~~~~~~~~~~~~~~~~ .. versionadded:: 2015.8.0 Default: ``False`` By default, Salt will not authenticate to an HTTP (non-HTTPS) remote. This parameter enables authentication over HTTP. **Enable this at your own risk.** .. code-block:: yaml git_pillar_insecure_auth: True .. conf_master:: git_pillar_pubkey ``git_pillar_pubkey`` ~~~~~~~~~~~~~~~~~~~~~ .. versionadded:: 2015.8.0 Default: ``''`` Along with :conf_master:`git_pillar_privkey` (and optionally :conf_master:`git_pillar_passphrase`), is used to authenticate to SSH remotes. .. code-block:: yaml git_pillar_pubkey: /path/to/key.pub .. conf_master:: git_pillar_privkey ``git_pillar_privkey`` ~~~~~~~~~~~~~~~~~~~~~~ .. versionadded:: 2015.8.0 Default: ``''`` Along with :conf_master:`git_pillar_pubkey` (and optionally :conf_master:`git_pillar_passphrase`), is used to authenticate to SSH remotes. .. code-block:: yaml git_pillar_privkey: /path/to/key .. conf_master:: git_pillar_passphrase ``git_pillar_passphrase`` ~~~~~~~~~~~~~~~~~~~~~~~~~ .. versionadded:: 2015.8.0 Default: ``''`` This parameter is optional, required only when the SSH key being used to authenticate is protected by a passphrase. .. code-block:: yaml git_pillar_passphrase: mypassphrase .. conf_master:: git_pillar_refspecs ``git_pillar_refspecs`` ~~~~~~~~~~~~~~~~~~~~~~~ .. versionadded:: 2017.7.0 Default: ``['+refs/heads/*:refs/remotes/origin/*', '+refs/tags/*:refs/tags/*']`` When fetching from remote repositories, by default Salt will fetch branches and tags. This parameter can be used to override the default and specify alternate refspecs to be fetched. This parameter works similarly to its :ref:`GitFS counterpart `, in that it can be configured both globally and for individual remotes. .. code-block:: yaml git_pillar_refspecs: - '+refs/heads/*:refs/remotes/origin/*' - '+refs/tags/*:refs/tags/*' - '+refs/pull/*/head:refs/remotes/origin/pr/*' - '+refs/pull/*/merge:refs/remotes/origin/merge/*' .. conf_master:: git_pillar_verify_config ``git_pillar_verify_config`` ---------------------------- .. versionadded:: 2017.7.0 Default: ``True`` By default, as the master starts it performs some sanity checks on the configured git_pillar repositories. If any of these sanity checks fail (such as when an invalid configuration is used), the master daemon will abort. To skip these sanity checks, set this option to ``False``. .. code-block:: yaml git_pillar_verify_config: False .. _pillar-merging-opts: Pillar Merging Options ---------------------- .. conf_master:: pillar_source_merging_strategy ``pillar_source_merging_strategy`` ********************************** .. versionadded:: 2014.7.0 Default: ``smart`` The pillar_source_merging_strategy option allows you to configure merging strategy between different sources. It accepts 5 values: * ``none``: It will not do any merging at all and only parse the pillar data from the passed environment and 'base' if no environment was specified. .. versionadded:: 2016.3.4 * ``recurse``: It will recursively merge data. For example, theses 2 sources: .. code-block:: yaml foo: 42 bar: element1: True .. code-block:: yaml bar: element2: True baz: quux will be merged as: .. code-block:: yaml foo: 42 bar: element1: True element2: True baz: quux * ``aggregate``: instructs aggregation of elements between sources that use the #!yamlex renderer. For example, these two documents: .. code-block:: yaml #!yamlex foo: 42 bar: !aggregate { element1: True } baz: !aggregate quux .. code-block:: yaml #!yamlex bar: !aggregate { element2: True } baz: !aggregate quux2 will be merged as: .. code-block:: yaml foo: 42 bar: element1: True element2: True baz: - quux - quux2 * ``overwrite``: Will use the behaviour of the 2014.1 branch and earlier. Overwrites elements according the order in which they are processed. First pillar processed: .. code-block:: yaml A: first_key: blah second_key: blah Second pillar processed: .. code-block:: yaml A: third_key: blah fourth_key: blah will be merged as: .. code-block:: yaml A: third_key: blah fourth_key: blah * ``smart`` (default): Guesses the best strategy based on the "renderer" setting. .. note:: In order for yamlex based features such as ``!aggregate`` to work as expected across documents using the default ``smart`` merge strategy, the :conf_master:`renderer` config option must be set to ``jinja|yamlex`` or similar. .. conf_master:: pillar_merge_lists ``pillar_merge_lists`` ********************** .. versionadded:: 2015.8.0 Default: ``False`` Recursively merge lists by aggregating them instead of replacing them. .. code-block:: yaml pillar_merge_lists: False .. conf_master:: pillar_includes_override_sls ``pillar_includes_override_sls`` ******************************** .. versionadded:: 2017.7.6,2018.3.1 Default: ``False`` Prior to version 2017.7.3, keys from :ref:`pillar includes ` would be merged on top of the pillar SLS. Since 2017.7.3, the includes are merged together and then the pillar SLS is merged on top of that. Set this option to ``True`` to return to the old behavior. .. code-block:: yaml pillar_includes_override_sls: True .. _pillar-cache-opts: Pillar Cache Options -------------------- .. conf_master:: pillar_cache ``pillar_cache`` **************** .. versionadded:: 2015.8.8 Default: ``False`` A master can cache pillars locally to bypass the expense of having to render them for each minion on every request. This feature should only be enabled in cases where pillar rendering time is known to be unsatisfactory and any attendant security concerns about storing pillars in a master cache have been addressed. When enabling this feature, be certain to read through the additional ``pillar_cache_*`` configuration options to fully understand the tunable parameters and their implications. .. code-block:: yaml pillar_cache: False .. note:: Setting ``pillar_cache: True`` has no effect on :ref:`targeting minions with pillar `. .. conf_master:: pillar_cache_ttl ``pillar_cache_ttl`` ******************** .. versionadded:: 2015.8.8 Default: ``3600`` If and only if a master has set ``pillar_cache: True``, the cache TTL controls the amount of time, in seconds, before the cache is considered invalid by a master and a fresh pillar is recompiled and stored. .. conf_master:: pillar_cache_backend ``pillar_cache_backend`` ************************ .. versionadded:: 2015.8.8 Default: ``disk`` If an only if a master has set ``pillar_cache: True``, one of several storage providers can be utilized: * ``disk`` (default): The default storage backend. This caches rendered pillars to the master cache. Rendered pillars are serialized and deserialized as ``msgpack`` structures for speed. Note that pillars are stored UNENCRYPTED. Ensure that the master cache has permissions set appropriately (sane defaults are provided). * ``memory`` [EXPERIMENTAL]: An optional backend for pillar caches which uses a pure-Python in-memory data structure for maximal performance. There are several caveats, however. First, because each master worker contains its own in-memory cache, there is no guarantee of cache consistency between minion requests. This works best in situations where the pillar rarely if ever changes. Secondly, and perhaps more importantly, this means that unencrypted pillars will be accessible to any process which can examine the memory of the ``salt-master``! This may represent a substantial security risk. .. code-block:: yaml pillar_cache_backend: disk Master Reactor Settings ======================= .. conf_master:: reactor ``reactor`` ----------- Default: ``[]`` Defines a salt reactor. See the :ref:`Reactor ` documentation for more information. .. code-block:: yaml reactor: - 'salt/minion/*/start': - salt://reactor/startup_tasks.sls .. conf_master:: reactor_refresh_interval ``reactor_refresh_interval`` ---------------------------- Default: ``60`` The TTL for the cache of the reactor configuration. .. code-block:: yaml reactor_refresh_interval: 60 .. conf_master:: reactor_worker_threads ``reactor_worker_threads`` -------------------------- Default: ``10`` The number of workers for the runner/wheel in the reactor. .. code-block:: yaml reactor_worker_threads: 10 .. conf_master:: reactor_worker_hwm ``reactor_worker_hwm`` ---------------------- Default: ``10000`` The queue size for workers in the reactor. .. code-block:: yaml reactor_worker_hwm: 10000 .. _salt-api-master-settings: Salt-API Master Settings ======================== There are some settings for :ref:`salt-api ` that can be configured on the Salt Master. .. conf_master:: api_logfile ``api_logfile`` --------------- Default: ``/var/log/salt/api`` The logfile location for ``salt-api``. .. code-block:: yaml api_logfile: /var/log/salt/api .. conf_master:: api_pidfile ``api_pidfile`` --------------- Default: /var/run/salt-api.pid If this master will be running ``salt-api``, specify the pidfile of the ``salt-api`` daemon. .. code-block:: yaml api_pidfile: /var/run/salt-api.pid .. conf_master:: rest_timeout ``rest_timeout`` ---------------- Default: ``300`` Used by ``salt-api`` for the master requests timeout. .. code-block:: yaml rest_timeout: 300 .. _syndic-server-settings: Syndic Server Settings ====================== A Salt syndic is a Salt master used to pass commands from a higher Salt master to minions below the syndic. Using the syndic is simple. If this is a master that will have syndic servers(s) below it, set the ``order_masters`` setting to ``True``. If this is a master that will be running a syndic daemon for passthrough the ``syndic_master`` setting needs to be set to the location of the master server. Do not forget that, in other words, it means that it shares with the local minion its ID and PKI directory. .. conf_master:: order_masters ``order_masters`` ----------------- Default: ``False`` Extra data needs to be sent with publications if the master is controlling a lower level master via a syndic minion. If this is the case the order_masters value must be set to True .. code-block:: yaml order_masters: False .. conf_master:: syndic_master ``syndic_master`` ----------------- .. versionchanged:: 2016.3.5,2016.11.1 Set default higher level master address. Default: ``masterofmasters`` If this master will be running the ``salt-syndic`` to connect to a higher level master, specify the higher level master with this configuration value. .. code-block:: yaml syndic_master: masterofmasters You can optionally connect a syndic to multiple higher level masters by setting the ``syndic_master`` value to a list: .. code-block:: yaml syndic_master: - masterofmasters1 - masterofmasters2 Each higher level master must be set up in a multi-master configuration. .. conf_master:: syndic_master_port ``syndic_master_port`` ---------------------- Default: ``4506`` If this master will be running the ``salt-syndic`` to connect to a higher level master, specify the higher level master port with this configuration value. .. code-block:: yaml syndic_master_port: 4506 .. conf_master:: syndic_pidfile ``syndic_pidfile`` ------------------ Default: ``/var/run/salt-syndic.pid`` If this master will be running the ``salt-syndic`` to connect to a higher level master, specify the pidfile of the syndic daemon. .. code-block:: yaml syndic_pidfile: /var/run/syndic.pid .. conf_master:: syndic_log_file ``syndic_log_file`` ------------------- Default: ``/var/log/salt/syndic`` If this master will be running the ``salt-syndic`` to connect to a higher level master, specify the log file of the syndic daemon. .. code-block:: yaml syndic_log_file: /var/log/salt-syndic.log .. conf_master:: syndic_failover ``syndic_failover`` ------------------- .. versionadded:: 2016.3.0 Default: ``random`` The behaviour of the multi-syndic when connection to a master of masters failed. Can specify ``random`` (default) or ``ordered``. If set to ``random``, masters will be iterated in random order. If ``ordered`` is specified, the configured order will be used. .. code-block:: yaml syndic_failover: random .. conf_master:: syndic_wait ``syndic_wait`` --------------- Default: ``5`` The number of seconds for the salt client to wait for additional syndics to check in with their lists of expected minions before giving up. .. code-block:: yaml syndic_wait: 5 .. conf_master:: syndic_forward_all_events ``syndic_forward_all_events`` ----------------------------- .. versionadded:: 2017.7.0 Default: ``False`` Option on multi-syndic or single when connected to multiple masters to be able to send events to all connected masters. .. code-block:: yaml syndic_forward_all_events: False .. _peer-publish-settings: Peer Publish Settings ===================== Salt minions can send commands to other minions, but only if the minion is allowed to. By default "Peer Publication" is disabled, and when enabled it is enabled for specific minions and specific commands. This allows secure compartmentalization of commands based on individual minions. .. conf_master:: peer ``peer`` -------- Default: ``{}`` The configuration uses regular expressions to match minions and then a list of regular expressions to match functions. The following will allow the minion authenticated as foo.example.com to execute functions from the test and pkg modules. .. code-block:: yaml peer: foo.example.com: - test.* - pkg.* This will allow all minions to execute all commands: .. code-block:: yaml peer: .*: - .* This is not recommended, since it would allow anyone who gets root on any single minion to instantly have root on all of the minions! By adding an additional layer you can limit the target hosts in addition to the accessible commands: .. code-block:: yaml peer: foo.example.com: 'db*': - test.* - pkg.* .. conf_master:: peer_run ``peer_run`` ------------ Default: ``{}`` The peer_run option is used to open up runners on the master to access from the minions. The peer_run configuration matches the format of the peer configuration. The following example would allow foo.example.com to execute the manage.up runner: .. code-block:: yaml peer_run: foo.example.com: - manage.up .. _master-logging-settings: Master Logging Settings ======================= .. conf_master:: log_file ``log_file`` ------------ Default: ``/var/log/salt/master`` The master log can be sent to a regular file, local path name, or network location. See also :conf_log:`log_file`. Examples: .. code-block:: yaml log_file: /var/log/salt/master .. code-block:: yaml log_file: file:///dev/log .. code-block:: yaml log_file: udp://loghost:10514 .. conf_master:: log_level ``log_level`` ------------- Default: ``warning`` The level of messages to send to the console. See also :conf_log:`log_level`. .. code-block:: yaml log_level: warning .. conf_master:: log_level_logfile ``log_level_logfile`` --------------------- Default: ``warning`` The level of messages to send to the log file. See also :conf_log:`log_level_logfile`. When it is not set explicitly it will inherit the level set by :conf_log:`log_level` option. .. code-block:: yaml log_level_logfile: warning .. conf_master:: log_datefmt ``log_datefmt`` --------------- Default: ``%H:%M:%S`` The date and time format used in console log messages. See also :conf_log:`log_datefmt`. .. code-block:: yaml log_datefmt: '%H:%M:%S' .. conf_master:: log_datefmt_logfile ``log_datefmt_logfile`` ----------------------- Default: ``%Y-%m-%d %H:%M:%S`` The date and time format used in log file messages. See also :conf_log:`log_datefmt_logfile`. .. code-block:: yaml log_datefmt_logfile: '%Y-%m-%d %H:%M:%S' .. conf_master:: log_fmt_console ``log_fmt_console`` ------------------- Default: ``[%(levelname)-8s] %(message)s`` The format of the console logging messages. See also :conf_log:`log_fmt_console`. .. note:: Log colors are enabled in ``log_fmt_console`` rather than the :conf_master:`color` config since the logging system is loaded before the master config. Console log colors are specified by these additional formatters: %(colorlevel)s %(colorname)s %(colorprocess)s %(colormsg)s Since it is desirable to include the surrounding brackets, '[' and ']', in the coloring of the messages, these color formatters also include padding as well. Color LogRecord attributes are only available for console logging. .. code-block:: yaml log_fmt_console: '%(colorlevel)s %(colormsg)s' log_fmt_console: '[%(levelname)-8s] %(message)s' .. conf_master:: log_fmt_logfile ``log_fmt_logfile`` ------------------- Default: ``%(asctime)s,%(msecs)03d [%(name)-17s][%(levelname)-8s] %(message)s`` The format of the log file logging messages. See also :conf_log:`log_fmt_logfile`. .. code-block:: yaml log_fmt_logfile: '%(asctime)s,%(msecs)03d [%(name)-17s][%(levelname)-8s] %(message)s' .. conf_master:: log_granular_levels ``log_granular_levels`` ----------------------- Default: ``{}`` This can be used to control logging levels more specifically. See also :conf_log:`log_granular_levels`. .. conf_master:: log_rotate_max_bytes ``log_rotate_max_bytes`` ------------------------ Default: ``0`` The maximum number of bytes a single log file may contain before it is rotated. A value of 0 disables this feature. Currently only supported on Windows. On other platforms, use an external tool such as 'logrotate' to manage log files. :conf_log:`log_rotate_max_bytes` .. conf_master:: log_rotate_backup_count ``log_rotate_backup_count`` --------------------------- Default: ``0`` The number of backup files to keep when rotating log files. Only used if :conf_master:`log_rotate_max_bytes` is greater than 0. Currently only supported on Windows. On other platforms, use an external tool such as 'logrotate' to manage log files. :conf_log:`log_rotate_backup_count` .. _node-groups: Node Groups =========== .. conf_master:: nodegroups ``nodegroups`` -------------- Default: ``{}`` Node groups allow for logical groupings of minion nodes. A group consists of a group name and a compound target. .. code-block:: yaml nodegroups: group1: 'L@foo.domain.com,bar.domain.com,baz.domain.com or bl*.domain.com' group2: 'G@os:Debian and foo.domain.com' group3: 'G@os:Debian and N@group1' group4: - 'G@foo:bar' - 'or' - 'G@foo:baz' More information on using nodegroups can be found :ref:`here `. .. _range-cluster-settings: Range Cluster Settings ====================== .. conf_master:: range_server ``range_server`` ---------------- Default: ``'range:80'`` The range server (and optional port) that serves your cluster information https://github.com/ytoolshed/range/wiki/%22yamlfile%22-module-file-spec .. code-block:: yaml range_server: range:80 .. _include-configuration: Include Configuration ===================== Configuration can be loaded from multiple files. The order in which this is done is: 1. The master config file itself 2. The files matching the glob in :conf_master:`default_include` 3. The files matching the glob in :conf_master:`include` (if defined) Each successive step overrides any values defined in the previous steps. Therefore, any config options defined in one of the :conf_master:`default_include` files would override the same value in the master config file, and any options defined in :conf_master:`include` would override both. .. conf_master:: default_include ``default_include`` ------------------- Default: ``master.d/*.conf`` The master can include configuration from other files. Per default the master will automatically include all config files from ``master.d/*.conf`` where ``master.d`` is relative to the directory of the master configuration file. .. note:: Salt creates files in the ``master.d`` directory for its own use. These files are prefixed with an underscore. A common example of this is the ``_schedule.conf`` file. .. conf_master:: include ``include`` ----------- Default: ``not defined`` The master can include configuration from other files. To enable this, pass a list of paths to this option. The paths can be either relative or absolute; if relative, they are considered to be relative to the directory the main minion configuration file lives in. Paths can make use of shell-style globbing. If no files are matched by a path passed to this option then the master will log a warning message. .. code-block:: yaml # Include files from a master.d directory in the same # directory as the master config file include: master.d/* # Include a single extra file into the configuration include: /etc/roles/webserver # Include several files and the master.d directory include: - extra_config - master.d/* - /etc/roles/webserver Keepalive Settings ================== .. conf_master:: tcp_keepalive ``tcp_keepalive`` ----------------- Default: ``True`` The tcp keepalive interval to set on TCP ports. This setting can be used to tune Salt connectivity issues in messy network environments with misbehaving firewalls. .. code-block:: yaml tcp_keepalive: True .. conf_master:: tcp_keepalive_cnt ``tcp_keepalive_cnt`` --------------------- Default: ``-1`` Sets the ZeroMQ TCP keepalive count. May be used to tune issues with minion disconnects. .. code-block:: yaml tcp_keepalive_cnt: -1 .. conf_master:: tcp_keepalive_idle ``tcp_keepalive_idle`` ---------------------- Default: ``300`` Sets ZeroMQ TCP keepalive idle. May be used to tune issues with minion disconnects. .. code-block:: yaml tcp_keepalive_idle: 300 .. conf_master:: tcp_keepalive_intvl ``tcp_keepalive_intvl`` ----------------------- Default: ``-1`` Sets ZeroMQ TCP keepalive interval. May be used to tune issues with minion disconnects. .. code-block:: yaml tcp_keepalive_intvl': -1 .. _winrepo-master-config-opts: Windows Software Repo Settings ============================== .. conf_master:: winrepo_provider ``winrepo_provider`` -------------------- .. versionadded:: 2015.8.0 Specify the provider to be used for winrepo. Must be either ``pygit2`` or ``gitpython``. If unset, then both will be tried in that same order, and the first one with a compatible version installed will be the provider that is used. .. code-block:: yaml winrepo_provider: gitpython .. conf_master:: winrepo_dir .. conf_master:: win_repo ``winrepo_dir`` --------------- .. versionchanged:: 2015.8.0 Renamed from ``win_repo`` to ``winrepo_dir``. Default: ``/srv/salt/win/repo`` Location on the master where the :conf_master:`winrepo_remotes` are checked out for pre-2015.8.0 minions. 2015.8.0 and later minions use :conf_master:`winrepo_remotes_ng ` instead. .. code-block:: yaml winrepo_dir: /srv/salt/win/repo .. conf_master:: winrepo_dir_ng ``winrepo_dir_ng`` ------------------ .. versionadded:: 2015.8.0 A new :ref:`ng ` repo was added. Default: ``/srv/salt/win/repo-ng`` Location on the master where the :conf_master:`winrepo_remotes_ng` are checked out for 2015.8.0 and later minions. .. code-block:: yaml winrepo_dir_ng: /srv/salt/win/repo-ng .. conf_master:: winrepo_cachefile .. conf_master:: win_repo_mastercachefile ``winrepo_cachefile`` --------------------- .. versionchanged:: 2015.8.0 Renamed from ``win_repo_mastercachefile`` to ``winrepo_cachefile`` .. note:: 2015.8.0 and later minions do not use this setting since the cachefile is now generated by the minion. Default: ``winrepo.p`` Path relative to :conf_master:`winrepo_dir` where the winrepo cache should be created. .. code-block:: yaml winrepo_cachefile: winrepo.p .. conf_master:: winrepo_remotes .. conf_master:: win_gitrepos ``winrepo_remotes`` ------------------- .. versionchanged:: 2015.8.0 Renamed from ``win_gitrepos`` to ``winrepo_remotes``. Default: ``['https://github.com/saltstack/salt-winrepo.git']`` List of git repositories to checkout and include in the winrepo for pre-2015.8.0 minions. 2015.8.0 and later minions use :conf_master:`winrepo_remotes_ng ` instead. .. code-block:: yaml winrepo_remotes: - https://github.com/saltstack/salt-winrepo.git To specify a specific revision of the repository, prepend a commit ID to the URL of the repository: .. code-block:: yaml winrepo_remotes: - ' https://github.com/saltstack/salt-winrepo.git' Replace ```` with the SHA1 hash of a commit ID. Specifying a commit ID is useful in that it allows one to revert back to a previous version in the event that an error is introduced in the latest revision of the repo. .. conf_master:: winrepo_remotes_ng ``winrepo_remotes_ng`` ---------------------- .. versionadded:: 2015.8.0 A new :ref:`ng ` repo was added. Default: ``['https://github.com/saltstack/salt-winrepo-ng.git']`` List of git repositories to checkout and include in the winrepo for 2015.8.0 and later minions. .. code-block:: yaml winrepo_remotes_ng: - https://github.com/saltstack/salt-winrepo-ng.git To specify a specific revision of the repository, prepend a commit ID to the URL of the repository: .. code-block:: yaml winrepo_remotes_ng: - ' https://github.com/saltstack/salt-winrepo-ng.git' Replace ```` with the SHA1 hash of a commit ID. Specifying a commit ID is useful in that it allows one to revert back to a previous version in the event that an error is introduced in the latest revision of the repo. .. conf_master:: winrepo_branch ``winrepo_branch`` ------------------ .. versionadded:: 2015.8.0 Default: ``master`` If the branch is omitted from a winrepo remote, then this branch will be used instead. For example, in the configuration below, the first two remotes would use the ``winrepo`` branch/tag, while the third would use the ``foo`` branch/tag. .. code-block:: yaml winrepo_branch: winrepo winrepo_remotes: - https://mygitserver/winrepo1.git - https://mygitserver/winrepo2.git: - foo https://mygitserver/winrepo3.git .. conf_master:: winrepo_ssl_verify ``winrepo_ssl_verify`` ---------------------- .. versionadded:: 2015.8.0 .. versionchanged:: 2016.11.0 Default: ``False`` Specifies whether or not to ignore SSL certificate errors when contacting the remote repository. The ``False`` setting is useful if you're using a git repo that uses a self-signed certificate. However, keep in mind that setting this to anything other ``True`` is a considered insecure, and using an SSH-based transport (if available) may be a better option. In the 2016.11.0 release, the default config value changed from ``False`` to ``True``. .. code-block:: yaml winrepo_ssl_verify: True Winrepo Authentication Options ------------------------------ These parameters only currently apply to the ``pygit2`` :conf_master:`winrepo_provider`. Authentication works the same as it does in gitfs, as outlined in the :ref:`GitFS Walkthrough `, though the global configuration options are named differently to reflect that they are for winrepo instead of gitfs. .. conf_master:: winrepo_user ``winrepo_user`` **************** .. versionadded:: 2015.8.0 Default: ``''`` Along with :conf_master:`winrepo_password`, is used to authenticate to HTTPS remotes. .. code-block:: yaml winrepo_user: git .. conf_master:: winrepo_password ``winrepo_password`` ******************** .. versionadded:: 2015.8.0 Default: ``''`` Along with :conf_master:`winrepo_user`, is used to authenticate to HTTPS remotes. This parameter is not required if the repository does not use authentication. .. code-block:: yaml winrepo_password: mypassword .. conf_master:: winrepo_insecure_auth ``winrepo_insecure_auth`` ************************* .. versionadded:: 2015.8.0 Default: ``False`` By default, Salt will not authenticate to an HTTP (non-HTTPS) remote. This parameter enables authentication over HTTP. **Enable this at your own risk.** .. code-block:: yaml winrepo_insecure_auth: True .. conf_master:: winrepo_pubkey ``winrepo_pubkey`` ****************** .. versionadded:: 2015.8.0 Default: ``''`` Along with :conf_master:`winrepo_privkey` (and optionally :conf_master:`winrepo_passphrase`), is used to authenticate to SSH remotes. .. code-block:: yaml winrepo_pubkey: /path/to/key.pub .. conf_master:: winrepo_privkey ``winrepo_privkey`` ******************* .. versionadded:: 2015.8.0 Default: ``''`` Along with :conf_master:`winrepo_pubkey` (and optionally :conf_master:`winrepo_passphrase`), is used to authenticate to SSH remotes. .. code-block:: yaml winrepo_privkey: /path/to/key .. conf_master:: winrepo_passphrase ``winrepo_passphrase`` ********************** .. versionadded:: 2015.8.0 Default: ``''`` This parameter is optional, required only when the SSH key being used to authenticate is protected by a passphrase. .. code-block:: yaml winrepo_passphrase: mypassphrase .. conf_master:: winrepo_refspecs ``winrepo_refspecs`` ~~~~~~~~~~~~~~~~~~~~ .. versionadded:: 2017.7.0 Default: ``['+refs/heads/*:refs/remotes/origin/*', '+refs/tags/*:refs/tags/*']`` When fetching from remote repositories, by default Salt will fetch branches and tags. This parameter can be used to override the default and specify alternate refspecs to be fetched. This parameter works similarly to its :ref:`GitFS counterpart `, in that it can be configured both globally and for individual remotes. .. code-block:: yaml winrepo_refspecs: - '+refs/heads/*:refs/remotes/origin/*' - '+refs/tags/*:refs/tags/*' - '+refs/pull/*/head:refs/remotes/origin/pr/*' - '+refs/pull/*/merge:refs/remotes/origin/merge/*' .. _configure-master-on-windows: Configure Master on Windows =========================== The master on Windows requires no additional configuration. You can modify the master configuration by creating/editing the master config file located at ``c:\salt\conf\master``. The same configuration options available on Linux are available in Windows, as long as they apply. For example, SSH options wouldn't apply in Windows. The main differences are the file paths. If you are familiar with common salt paths, the following table may be useful: ============= ========= ================= linux Paths Windows Paths ============= ========= ================= ``/etc/salt`` ``<--->`` ``c:\salt\conf`` ``/`` ``<--->`` ``c:\salt`` ============= ========= ================= So, for example, the master config file in Linux is ``/etc/salt/master``. In Windows the master config file is ``c:\salt\conf\master``. The Linux path ``/etc/salt`` becomes ``c:\salt\conf`` in Windows.
