.. _configuration-salt-minion: =========================== Configuring the Salt Minion =========================== The Salt system is amazingly simple and easy to configure. The two components of the Salt system each have a respective configuration file. The :command:`salt-master` is configured via the master configuration file, and the :command:`salt-minion` is configured via the minion configuration file. .. seealso:: :ref:`example minion configuration file ` The Salt Minion configuration is very simple. Typically, the only value that needs to be set is the master value so the minion knows where to locate its master. By default, the salt-minion configuration will be in :file:`/etc/salt/minion`. A notable exception is FreeBSD, where the configuration will be in :file:`/usr/local/etc/salt/minion`. Minion Primary Configuration ============================ .. conf_minion:: master ``master`` ---------- Default: ``salt`` The hostname or IP address of the master. See :conf_minion:`ipv6` for IPv6 connections to the master. Default: ``salt`` .. code-block:: yaml master: salt master:port Syntax ~~~~~~~~~~~~~~~~~~ .. versionadded:: 2015.8.0 The ``master`` config option can also be set to use the master's IP in conjunction with a port number by default. .. code-block:: yaml master: localhost:1234 For IPv6 formatting with a port, remember to add brackets around the IP address before adding the port and enclose the line in single quotes to make it a string: .. code-block:: yaml master: '[2001:db8:85a3:8d3:1319:8a2e:370:7348]:1234' .. note:: If a port is specified in the ``master`` as well as :conf_minion:`master_port`, the ``master_port`` setting will be overridden by the ``master`` configuration. List of Masters Syntax ~~~~~~~~~~~~~~~~~~~~~~ The option can also be set to a list of masters, enabling :ref:`multi-master ` mode. .. code-block:: yaml master: - address1 - address2 .. versionchanged:: 2014.7.0 The master can be dynamically configured. The :conf_minion:`master` value can be set to an module function which will be executed and will assume that the returning value is the ip or hostname of the desired master. If a function is being specified, then the :conf_minion:`master_type` option must be set to ``func``, to tell the minion that the value is a function to be run and not a fully-qualified domain name. .. code-block:: yaml master: module.function master_type: func In addition, instead of using multi-master mode, the minion can be configured to use the list of master addresses as a failover list, trying the first address, then the second, etc. until the minion successfully connects. To enable this behavior, set :conf_minion:`master_type` to ``failover``: .. code-block:: yaml master: - address1 - address2 master_type: failover .. conf_minion:: ipv6 ``ipv6`` -------- Default: ``None`` Whether the master should be connected over IPv6. By default salt minion will try to automatically detect IPv6 connectivity to master. .. code-block:: yaml ipv6: True .. conf_minion:: master_uri_format ``master_uri_format`` --------------------- .. versionadded:: 2015.8.0 Specify the format in which the master address will be evaluated. Valid options are ``default`` or ``ip_only``. If ``ip_only`` is specified, then the master address will not be split into IP and PORT, so be sure that only an IP (or domain name) is set in the :conf_minion:`master` configuration setting. .. code-block:: yaml master_uri_format: ip_only .. conf_minion:: master_tops_first ``master_tops_first`` --------------------- .. versionadded:: 2018.3.0 Default: ``False`` SLS targets defined using the :ref:`Master Tops ` system are normally executed *after* any matches defined in the :ref:`Top File `. Set this option to ``True`` to have the minion execute the :ref:`Master Tops ` states first. .. code-block:: yaml master_tops_first: True .. conf_minion:: master_type ``master_type`` --------------- .. versionadded:: 2014.7.0 Default: ``str`` The type of the :conf_minion:`master` variable. Can be ``str``, ``failover``, ``func`` or ``disable``. .. code-block:: yaml master_type: failover If this option is set to ``failover``, :conf_minion:`master` must be a list of master addresses. The minion will then try each master in the order specified in the list until it successfully connects. :conf_minion:`master_alive_interval` must also be set, this determines how often the minion will verify the presence of the master. .. code-block:: yaml master_type: func If the master needs to be dynamically assigned by executing a function instead of reading in the static master value, set this to ``func``. This can be used to manage the minion's master setting from an execution module. By simply changing the algorithm in the module to return a new master ip/fqdn, restart the minion and it will connect to the new master. As of version 2016.11.0 this option can be set to ``disable`` and the minion will never attempt to talk to the master. This is useful for running a masterless minion daemon. .. code-block:: yaml master_type: disable .. conf_minion:: 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 minion event bus. The value is expressed in bytes. .. code-block:: yaml max_event_size: 1048576 .. conf_minion:: enable_legacy_startup_events ``enable_legacy_startup_events`` -------------------------------- .. versionadded:: 2019.2.0 Default: ``True`` When a minion starts up it sends a notification on the event bus with a tag that looks like this: ``salt/minion//start``. For historical reasons the minion also sends a similar event with an event tag like this: ``minion_start``. This duplication can cause a lot of clutter on the event bus when there are many minions. Set ``enable_legacy_startup_events: False`` in the minion config to ensure only the ``salt/minion//start`` events are sent. Beginning with the ``Sodium`` Salt release this option will default to ``False``. .. code-block:: yaml enable_legacy_startup_events: True .. conf_minion:: master_failback ``master_failback`` ------------------- .. versionadded:: 2016.3.0 Default: ``False`` If the minion is in multi-master mode and the :conf_minion`master_type` configuration option is set to ``failover``, this setting can be set to ``True`` to force the minion to fail back to the first master in the list if the first master is back online. .. code-block:: yaml master_failback: False .. conf_minion:: master_failback_interval ``master_failback_interval`` ---------------------------- .. versionadded:: 2016.3.0 Default: ``0`` If the minion is in multi-master mode, the :conf_minion`master_type` configuration is set to ``failover``, and the ``master_failback`` option is enabled, the master failback interval can be set to ping the top master with this interval, in seconds. .. code-block:: yaml master_failback_interval: 0 .. conf_minion:: master_alive_interval ``master_alive_interval`` ------------------------- Default: ``0`` Configures how often, in seconds, the minion will verify that the current master is alive and responding. The minion will try to establish a connection to the next master in the list if it finds the existing one is dead. .. code-block:: yaml master_alive_interval: 30 .. conf_minion:: master_shuffle ``master_shuffle`` ------------------ .. versionadded:: 2014.7.0 .. deprecated:: 2019.2.0 Default: ``False`` .. warning:: This option has been deprecated in Salt ``2019.2.0``. Please use :conf_minion:`random_master` instead. .. code-block:: yaml master_shuffle: True .. conf_minion:: random_master ``random_master`` ----------------- .. versionadded:: 2014.7.0 .. versionchanged:: 2019.2.0 The :conf_minion:`master_failback` option can be used in conjunction with ``random_master`` to force the minion to fail back to the first master in the list if the first master is back online. Note that :conf_minion:`master_type` must be set to ``failover`` in order for the ``master_failback`` setting to work. Default: ``False`` If :conf_minion:`master` is a list of addresses, shuffle them before trying to connect to distribute the minions over all available masters. This uses Python's :func:`random.shuffle ` method. If multiple masters are specified in the 'master' setting as a list, the default behavior is to always try to connect to them in the order they are listed. If ``random_master`` is set to True, the order will be randomized instead upon Minion startup. This can be helpful in distributing the load of many minions executing ``salt-call`` requests, for example, from a cron job. If only one master is listed, this setting is ignored and a warning is logged. .. code-block:: yaml random_master: True .. note:: When the ``failover``, ``master_failback``, and ``random_master`` options are used together, only the "secondary masters" will be shuffled. The first master in the list is ignored in the :func:`random.shuffle ` call. See :conf_minion:`master_failback` for more information. .. conf_minion:: retry_dns ``retry_dns`` ------------- Default: ``30`` Set the number of seconds to wait before attempting to resolve the master hostname if name resolution fails. Defaults to 30 seconds. Set to zero if the minion should shutdown and not retry. .. code-block:: yaml retry_dns: 30 .. conf_minion:: retry_dns_count ``retry_dns_count`` ------------------- .. versionadded:: 2018.3.4 Default: ``None`` Set the number of attempts to perform when resolving the master hostname if name resolution fails. By default the minion will retry indefinitely. .. code-block:: yaml retry_dns_count: 3 .. conf_minion:: master_port ``master_port`` --------------- Default: ``4506`` The port of the master ret server, this needs to coincide with the ret_port option on the Salt master. .. code-block:: yaml master_port: 4506 .. conf_minion:: publish_port ``publish_port`` ---------------- Default: ``4505`` The port of the master publish server, this needs to coincide with the publish_port option on the Salt master. .. code-block:: yaml publish_port: 4505 .. conf_minion:: source_interface_name ``source_interface_name`` ------------------------- .. versionadded:: 2018.3.0 The name of the interface to use when establishing the connection to the Master. .. note:: If multiple IP addresses are configured on the named interface, the first one will be selected. In that case, for a better selection, consider using the :conf_minion:`source_address` option. .. note:: To use an IPv6 address from the named interface, make sure the option :conf_minion:`ipv6` is enabled, i.e., ``ipv6: true``. .. note:: If the interface is down, it will avoid using it, and the Minion will bind to ``0.0.0.0`` (all interfaces). .. warning:: This option requires modern version of the underlying libraries used by the selected transport: - ``zeromq`` requires ``pyzmq`` >= 16.0.1 and ``libzmq`` >= 4.1.6 - ``tcp`` requires ``tornado`` >= 4.5 Configuration example: .. code-block:: yaml source_interface_name: bond0.1234 .. conf_minion:: source_address ``source_address`` ------------------ .. versionadded:: 2018.3.0 The source IP address or the domain name to be used when connecting the Minion to the Master. See :conf_minion:`ipv6` for IPv6 connections to the Master. .. warning:: This option requires modern version of the underlying libraries used by the selected transport: - ``zeromq`` requires ``pyzmq`` >= 16.0.1 and ``libzmq`` >= 4.1.6 - ``tcp`` requires ``tornado`` >= 4.5 Configuration example: .. code-block:: yaml source_address: if-bond0-1234.sjc.us-west.internal .. conf_minion:: source_ret_port ``source_ret_port`` ------------------- .. versionadded:: 2018.3.0 The source port to be used when connecting the Minion to the Master ret server. .. warning:: This option requires modern version of the underlying libraries used by the selected transport: - ``zeromq`` requires ``pyzmq`` >= 16.0.1 and ``libzmq`` >= 4.1.6 - ``tcp`` requires ``tornado`` >= 4.5 Configuration example: .. code-block:: yaml source_ret_port: 49017 .. conf_minion:: source_publish_port ``source_publish_port`` ----------------------- .. versionadded:: 2018.3.0 The source port to be used when connecting the Minion to the Master publish server. .. warning:: This option requires modern version of the underlying libraries used by the selected transport: - ``zeromq`` requires ``pyzmq`` >= 16.0.1 and ``libzmq`` >= 4.1.6 - ``tcp`` requires ``tornado`` >= 4.5 Configuration example: .. code-block:: yaml source_publish_port: 49018 .. conf_minion:: user ``user`` -------- Default: ``root`` The user to run the Salt processes .. code-block:: yaml user: root .. conf_minion:: sudo_user ``sudo_user`` ------------- Default: ``''`` The user to run salt remote execution commands as via sudo. If this option is enabled then sudo will be used to change the active user executing the remote command. If enabled the user will need to be allowed access via the sudoers file for the user that the salt minion is configured to run as. The most common option would be to use the root user. If this option is set the ``user`` option should also be set to a non-root user. If migrating from a root minion to a non root minion the minion cache should be cleared and the minion pki directory will need to be changed to the ownership of the new user. .. code-block:: yaml sudo_user: root ``pidfile`` ----------- Default: ``/var/run/salt-minion.pid`` The location of the daemon's process ID file .. code-block:: yaml pidfile: /var/run/salt-minion.pid .. conf_minion:: root_dir ``root_dir`` ------------ Default: ``/`` This directory is prepended to the following options: :conf_minion:`pki_dir`, :conf_minion:`cachedir`, :conf_minion:`log_file`, :conf_minion:`sock_dir`, and :conf_minion:`pidfile`. .. code-block:: yaml root_dir: / .. conf_minion:: conf_file ``conf_file`` ------------- Default: ``/etc/salt/minion`` The path to the minion's configuration file. .. code-block:: yaml conf_file: /etc/salt/minion .. conf_minion:: pki_dir ``pki_dir`` ----------- Default: ``/etc/salt/pki/minion`` The directory used to store the minion's public and private keys. .. code-block:: yaml pki_dir: /etc/salt/pki/minion .. conf_minion:: id ``id`` ------ Default: the system's hostname .. seealso:: :ref:`Salt Walkthrough ` The :strong:`Setting up a Salt Minion` section contains detailed information on how the hostname is determined. Explicitly declare the id for this minion to use. Since Salt uses detached ids it is possible to run multiple minions on the same machine but with different ids. .. code-block:: yaml id: foo.bar.com .. conf_minion:: minion_id_caching ``minion_id_caching`` --------------------- .. versionadded:: 0.17.2 Default: ``True`` Caches the minion id to a file when the minion's :conf_minion:`id` is not statically defined in the minion config. This setting prevents potential problems when automatic minion id resolution changes, which can cause the minion to lose connection with the master. To turn off minion id caching, set this config to ``False``. For more information, please see `Issue #7558`_ and `Pull Request #8488`_. .. code-block:: yaml minion_id_caching: True .. _Issue #7558: https://github.com/saltstack/salt/issues/7558 .. _Pull Request #8488: https://github.com/saltstack/salt/pull/8488 .. conf_minion:: append_domain ``append_domain`` ----------------- Default: ``None`` Append a domain to a hostname in the event that it does not exist. This is useful for systems where ``socket.getfqdn()`` does not actually result in a FQDN (for instance, Solaris). .. code-block:: yaml append_domain: foo.org .. conf_minion:: minion_id_lowercase ``minion_id_lowercase`` ----------------------- Default: ``False`` Convert minion id to lowercase when it is being generated. Helpful when some hosts get the minion id in uppercase. Cached ids will remain the same and not converted. .. code-block:: yaml minion_id_lowercase: True .. conf_minion:: cachedir ``cachedir`` ------------ Default: ``/var/cache/salt/minion`` The location for minion cache data. This directory may contain sensitive data and should be protected accordingly. .. code-block:: yaml cachedir: /var/cache/salt/minion .. 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_minion:: append_minionid_config_dirs ``append_minionid_config_dirs`` ------------------------------- Default: ``[]`` (the empty list) for regular minions, ``['cachedir']`` for proxy minions. Append minion_id to these configuration directories. Helps with multiple proxies and minions running on the same machine. Allowed elements in the list: ``pki_dir``, ``cachedir``, ``extension_modules``. Normally not needed unless running several proxies and/or minions on the same machine. .. code-block:: yaml append_minionid_config_dirs: - pki_dir - cachedir ``verify_env`` -------------- Default: ``True`` Verify and set permissions on configuration directories at startup. .. code-block:: yaml verify_env: True .. note:: When set to ``True`` the verify_env option requires WRITE access to the configuration directory (/etc/salt/). In certain situations such as mounting /etc/salt/ as read-only for templating this will create a stack trace when :py:func:`state.apply ` is called. .. conf_minion:: cache_jobs ``cache_jobs`` -------------- Default: ``False`` The minion can locally cache the return data from jobs sent to it, this can be a good way to keep track of the minion side of the jobs the minion has executed. By default this feature is disabled, to enable set cache_jobs to ``True``. .. code-block:: yaml cache_jobs: False .. conf_minion:: grains ``grains`` ---------- Default: (empty) .. seealso:: :ref:`static-custom-grains` Statically assigns grains to the minion. .. code-block:: yaml grains: roles: - webserver - memcache deployment: datacenter4 cabinet: 13 cab_u: 14-15 .. conf_minion:: grains_blacklist ``grains_blacklist`` -------------------- Default: ``[]`` Each grains key will be compared against each of the expressions in this list. Any keys which match will be filtered from the grains. Exact matches, glob matches, and regular expressions are supported. .. note:: Some states and execution modules depend on grains. Filtering may cause them to be unavailable or run unreliably. .. versionadded:: Neon .. code-block:: yaml grains_blacklist: - cpu_flags - zmq* - ipv[46] .. conf_minion:: grains_cache ``grains_cache`` ---------------- Default: ``False`` The minion can locally cache grain data instead of refreshing the data each time the grain is referenced. By default this feature is disabled, to enable set grains_cache to ``True``. .. code-block:: yaml grains_cache: False .. conf_minion:: grains_deep_merge ``grains_deep_merge`` --------------------- .. versionadded:: 2016.3.0 Default: ``False`` The grains can be merged, instead of overridden, using this option. This allows custom grains to defined different subvalues of a dictionary grain. By default this feature is disabled, to enable set grains_deep_merge to ``True``. .. code-block:: yaml grains_deep_merge: False For example, with these custom grains functions: .. code-block:: python def custom1_k1(): return {'custom1': {'k1': 'v1'}} def custom1_k2(): return {'custom1': {'k2': 'v2'}} Without ``grains_deep_merge``, the result would be: .. code-block:: yaml custom1: k1: v1 With ``grains_deep_merge``, the result will be: .. code-block:: yaml custom1: k1: v1 k2: v2 .. conf_minion:: grains_refresh_every ``grains_refresh_every`` ------------------------ Default: ``0`` The ``grains_refresh_every`` setting allows for a minion to periodically check its grains to see if they have changed and, if so, to inform the master of the new grains. This operation is moderately expensive, therefore care should be taken not to set this value too low. Note: This value is expressed in minutes. A value of 10 minutes is a reasonable default. .. code-block:: yaml grains_refresh_every: 0 .. conf_minion:: metadata_server_grains ``metadata_server_grains`` -------------------------- .. versionadded:: 2017.7.0 Default: ``False`` Set this option to enable gathering of cloud metadata from ``http://169.254.169.254/latest`` for use in grains (see :py:mod:`here ` for more information). .. code-block:: yaml metadata_server_grains: True .. conf_minion:: fibre_channel_grains ``fibre_channel_grains`` ------------------------ Default: ``False`` The ``fibre_channel_grains`` setting will enable the ``fc_wwn`` grain for Fibre Channel WWN's on the minion. Since this grain is expensive, it is disabled by default. .. code-block:: yaml fibre_channel_grains: True .. conf_minion:: iscsi_grains ``iscsi_grains`` ------------------------ Default: ``False`` The ``iscsi_grains`` setting will enable the ``iscsi_iqn`` grain on the minion. Since this grain is expensive, it is disabled by default. .. code-block:: yaml iscsi_grains: True .. conf_minion:: nvme_grains ``nvme_grains`` ------------------------ Default: ``False`` The ``nvme_grains`` setting will enable the ``nvme_nqn`` grain on the minion. Since this grain is expensive, it is disabled by default. .. code-block:: yaml nvme_grains: True .. conf_minion:: mine_enabled ``mine_enabled`` ---------------- .. versionadded:: 2015.8.10 Default: ``True`` Determines whether or not the salt minion should run scheduled mine updates. If this is set to False then the mine update function will not get added to the scheduler for the minion. .. code-block:: yaml mine_enabled: True .. conf_minion:: mine_return_job ``mine_return_job`` ------------------- .. versionadded:: 2015.8.10 Default: ``False`` Determines whether or not scheduled mine updates should be accompanied by a job return for the job cache. .. code-block:: yaml mine_return_job: False ``mine_functions`` ------------------ Default: Empty Designate which functions should be executed at mine_interval intervals on each minion. :ref:`See this documentation on the Salt Mine ` for more information. Note these can be defined in the pillar for a minion as well. :ref:`example minion configuration file ` .. code-block:: yaml mine_functions: test.ping: [] network.ip_addrs: interface: eth0 cidr: '10.0.0.0/8' .. conf_minion:: mine_interval ``mine_interval`` ----------------- Default: ``60`` The number of minutes between mine updates. .. code-block:: yaml mine_interval: 60 .. conf_minion:: sock_dir ``sock_dir`` ------------ Default: ``/var/run/salt/minion`` The directory where Unix sockets will be kept. .. code-block:: yaml sock_dir: /var/run/salt/minion .. conf_minion:: enable_gpu_grains ``enable_gpu_grains`` --------------------- Default: ``True`` Enable GPU hardware data for your master. Be aware that the minion can take a while to start up when lspci and/or dmidecode is used to populate the grains for the minion, so this can be set to ``False`` if you do not need these grains. .. code-block:: yaml enable_gpu_grains: False .. conf_minion:: outputter_dirs ``outputter_dirs`` ------------------ Default: ``[]`` A list of additional directories to search for salt outputters in. .. code-block:: yaml outputter_dirs: [] .. conf_minion:: backup_mode ``backup_mode`` --------------- Default: ``''`` Make backups of files replaced by ``file.managed`` and ``file.recurse`` state modules under :conf_minion:`cachedir` in ``file_backup`` subdirectory preserving original paths. Refer to :ref:`File State Backups documentation ` for more details. .. code-block:: yaml backup_mode: minion .. conf_minion:: acceptance_wait_time ``acceptance_wait_time`` ------------------------ Default: ``10`` The number of seconds to wait until attempting to re-authenticate with the master. .. code-block:: yaml acceptance_wait_time: 10 .. conf_minion:: acceptance_wait_time_max ``acceptance_wait_time_max`` ---------------------------- Default: ``0`` The maximum number of seconds to wait until attempting to re-authenticate with the master. If set, the wait will increase by :conf_minion:`acceptance_wait_time` seconds each iteration. .. code-block:: yaml acceptance_wait_time_max: 0 .. conf_minion:: rejected_retry ``rejected_retry`` ------------------ Default: ``False`` If the master rejects the minion's public key, retry instead of exiting. Rejected keys will be handled the same as waiting on acceptance. .. code-block:: yaml rejected_retry: False .. conf_minion:: random_reauth_delay ``random_reauth_delay`` ----------------------- Default: ``10`` When the master key changes, the minion will try to re-auth itself to receive the new master key. In larger environments this can cause a syn-flood on the master because all minions try to re-auth immediately. To prevent this and have a minion wait for a random amount of time, use this optional parameter. The wait-time will be a random number of seconds between 0 and the defined value. .. code-block:: yaml random_reauth_delay: 60 .. conf_minion:: master_tries ``master_tries`` ---------------- .. versionadded:: 2016.3.0 Default: ``1`` The number of attempts to connect to a master before giving up. Set this to ``-1`` for unlimited attempts. This allows for a master to have downtime and the minion to reconnect to it later when it comes back up. In 'failover' mode, which is set in the :conf_minion:`master_type` configuration, this value is the number of attempts for each set of masters. In this mode, it will cycle through the list of masters for each attempt. ``master_tries`` is different than :conf_minion:`auth_tries` because ``auth_tries`` attempts to retry auth attempts with a single master. ``auth_tries`` is under the assumption that you can connect to the master but not gain authorization from it. ``master_tries`` will still cycle through all of the masters in a given try, so it is appropriate if you expect occasional downtime from the master(s). .. code-block:: yaml master_tries: 1 .. conf_minion:: auth_tries ``auth_tries`` -------------- .. versionadded:: 2014.7.0 Default: ``7`` The number of attempts to authenticate to a master before giving up. Or, more technically, the number of consecutive SaltReqTimeoutErrors that are acceptable when trying to authenticate to the master. .. code-block:: yaml auth_tries: 7 .. conf_minion:: auth_timeout ``auth_timeout`` ---------------- .. versionadded:: 2014.7.0 Default: ``60`` When waiting for a master to accept the minion's public key, salt will continuously attempt to reconnect until successful. This is the timeout value, in seconds, for each individual attempt. After this timeout expires, the minion will wait for :conf_minion:`acceptance_wait_time` seconds before trying again. Unless your master is under unusually heavy load, this should be left at the default. .. code-block:: yaml auth_timeout: 60 .. conf_minion:: auth_safemode ``auth_safemode`` ----------------- .. versionadded:: 2014.7.0 Default: ``False`` If authentication fails due to SaltReqTimeoutError during a ping_interval, this setting, when set to ``True``, will cause a sub-minion process to restart. .. code-block:: yaml auth_safemode: False .. conf_minion:: ping_interval ``ping_interval`` ----------------- Default: ``0`` Instructs the minion to ping its master(s) every n number of minutes. Used primarily as a mitigation technique against minion disconnects. .. code-block:: yaml ping_interval: 0 .. conf_minion:: recon_default ``random_startup_delay`` ------------------------ Default: ``0`` The maximum bound for an interval in which a minion will randomly sleep upon starting up prior to attempting to connect to a master. This can be used to splay connection attempts for cases where many minions starting up at once may place undue load on a master. For example, setting this to ``5`` will tell a minion to sleep for a value between ``0`` and ``5`` seconds. .. code-block:: yaml random_startup_delay: 5 .. conf_minion:: random_startup_delay ``recon_default`` ----------------- Default: ``1000`` The interval in milliseconds that the socket should wait before trying to reconnect to the master (1000ms = 1 second). .. code-block:: yaml recon_default: 1000 .. conf_minion:: recon_max ``recon_max`` ------------- Default: ``10000`` The maximum time a socket should wait. Each interval the time to wait is calculated by doubling the previous time. If recon_max is reached, it starts again at the recon_default. Short example: - reconnect 1: the socket will wait 'recon_default' milliseconds - reconnect 2: 'recon_default' * 2 - reconnect 3: ('recon_default' * 2) * 2 - reconnect 4: value from previous interval * 2 - reconnect 5: value from previous interval * 2 - reconnect x: if value >= recon_max, it starts again with recon_default .. code-block:: yaml recon_max: 10000 .. conf_minion:: recon_randomize ``recon_randomize`` ------------------- Default: ``True`` Generate a random wait time on minion start. The wait time will be a random value between recon_default and recon_default + recon_max. Having all minions reconnect with the same recon_default and recon_max value kind of defeats the purpose of being able to change these settings. If all minions have the same values and the setup is quite large (several thousand minions), they will still flood the master. The desired behavior is to have time-frame within all minions try to reconnect. .. code-block:: yaml recon_randomize: True .. conf_minion:: loop_interval ``loop_interval`` ----------------- Default: ``1`` The loop_interval sets how long in seconds the minion will wait between evaluating the scheduler and running cleanup tasks. This defaults to 1 second on the minion scheduler. .. code-block:: yaml loop_interval: 1 .. conf_minion:: pub_ret ``pub_ret`` ----------- Default: True Some installations choose to start all job returns in a cache or a returner and forgo sending the results back to a master. In this workflow, jobs are most often executed with --async from the Salt CLI and then results are evaluated by examining job caches on the minions or any configured returners. WARNING: Setting this to False will **disable** returns back to the master. .. code-block:: yaml pub_ret: True .. conf_minion:: return_retry_timer ``return_retry_timer`` ---------------------- Default: ``5`` The default timeout for a minion return attempt. .. code-block:: yaml return_retry_timer: 5 .. conf_minion:: return_retry_timer_max ``return_retry_timer_max`` -------------------------- Default: ``10`` The maximum timeout for a minion return attempt. If non-zero the minion return retry timeout will be a random int between ``return_retry_timer`` and ``return_retry_timer_max`` .. code-block:: yaml return_retry_timer_max: 10 .. conf_minion:: cache_sreqs ``cache_sreqs`` --------------- Default: ``True`` The connection to the master ret_port is kept open. When set to False, the minion creates a new connection for every return to the master. .. code-block:: yaml cache_sreqs: True .. conf_minion:: ipc_mode ``ipc_mode`` ------------ Default: ``ipc`` Windows platforms lack POSIX IPC and must rely on slower TCP based inter- process communications. ``ipc_mode`` is set to ``tcp`` on such systems. .. code-block:: yaml ipc_mode: ipc .. conf_minion:: tcp_pub_port ``tcp_pub_port`` ---------------- Default: ``4510`` Publish port used when :conf_minion:`ipc_mode` is set to ``tcp``. .. code-block:: yaml tcp_pub_port: 4510 .. conf_minion:: tcp_pull_port ``tcp_pull_port`` ----------------- Default: ``4511`` Pull port used when :conf_minion:`ipc_mode` is set to ``tcp``. .. code-block:: yaml tcp_pull_port: 4511 .. conf_minion:: 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_minion:: syndic_finger ``syndic_finger`` ----------------- Default: ``''`` The key fingerprint of the higher-level master for the syndic to verify it is talking to the intended master. .. code-block:: yaml syndic_finger: 'ab:30:65:2a:d6:9e:20:4f:d8:b2:f3:a7:d4:65:50:10' .. conf_minion:: 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_minion:: 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 .. conf_minion:: proxy_host ``proxy_host`` -------------- Default: ``''`` The hostname used for HTTP proxy access. .. code-block:: yaml proxy_host: proxy.my-domain .. conf_minion:: proxy_port ``proxy_port`` -------------- Default: ``0`` The port number used for HTTP proxy access. .. code-block:: yaml proxy_port: 31337 .. conf_minion:: proxy_username ``proxy_username`` ------------------ Default: ``''`` The username used for HTTP proxy access. .. code-block:: yaml proxy_username: charon .. conf_minion:: proxy_password ``proxy_password`` ------------------ Default: ``''`` The password used for HTTP proxy access. .. code-block:: yaml proxy_password: obolus .. conf_minion:: no_proxy ``no_proxy`` ------------ .. versionadded:: 2019.2.0 Default: ``[]`` List of hosts to bypass HTTP proxy .. note:: This key does nothing unless proxy_host etc is configured, it does not support any kind of wildcards. .. code-block:: yaml no_proxy: [ '127.0.0.1', 'foo.tld' ] Docker Configuration ==================== .. conf_minion:: docker.update_mine ``docker.update_mine`` ---------------------- .. versionadded:: 2017.7.8,2018.3.3 .. versionchanged:: 2019.2.0 The default value is now ``False`` Default: ``True`` If enabled, when containers are added, removed, stopped, started, etc., the :ref:`mine ` will be updated with the results of :py:func:`docker.ps verbose=True all=True host=True `. This mine data is used by :py:func:`mine.get_docker `. Set this option to ``False`` to keep Salt from updating the mine with this information. .. note:: This option can also be set in Grains or Pillar data, with Grains overriding Pillar and the minion config file overriding Grains. .. note:: Disabling this will of course keep :py:func:`mine.get_docker ` from returning any information for a given minion. .. code-block:: yaml docker.update_mine: False .. conf_minion:: docker.compare_container_networks ``docker.compare_container_networks`` ------------------------------------- .. versionadded:: 2018.3.0 Default: ``{'static': ['Aliases', 'Links', 'IPAMConfig'], 'automatic': ['IPAddress', 'Gateway', 'GlobalIPv6Address', 'IPv6Gateway']}`` Specifies which keys are examined by :py:func:`docker.compare_container_networks `. .. note:: This should not need to be modified unless new features added to Docker result in new keys added to the network configuration which must be compared to determine if two containers have different network configs. This config option exists solely as a way to allow users to continue using Salt to manage their containers after an API change, without waiting for a new Salt release to catch up to the changes in the Docker API. .. code-block:: yaml docker.compare_container_networks: static: - Aliases - Links - IPAMConfig automatic: - IPAddress - Gateway - GlobalIPv6Address - IPv6Gateway .. conf_minion:: 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 Minion Execution Module Management ================================== .. conf_minion:: disable_modules ``disable_modules`` ------------------- Default: ``[]`` (all execution modules are enabled by default) The event may occur in which the administrator desires that a minion should not be able to execute a certain module. However, the ``sys`` module is built into the minion and cannot be disabled. This setting can also tune the minion. Because all modules are loaded into system memory, disabling modules will lower the minion's memory footprint. Modules should be specified according to their file name on the system and not by their virtual name. For example, to disable ``cmd``, use the string ``cmdmod`` which corresponds to ``salt.modules.cmdmod``. .. code-block:: yaml disable_modules: - test - solr .. conf_minion:: disable_returners ``disable_returners`` --------------------- Default: ``[]`` (all returners are enabled by default) If certain returners should be disabled, this is the place .. code-block:: yaml disable_returners: - mongo_return .. conf_minion:: enable_whitelist_modules ``whitelist_modules`` --------------------- Default: ``[]`` (Module whitelisting is disabled. Adding anything to the config option will cause only the listed modules to be enabled. Modules not in the list will not be loaded.) This option is the reverse of disable_modules. If enabled, only execution modules in this list will be loaded and executed on the minion. Note that this is a very large hammer and it can be quite difficult to keep the minion working the way you think it should since Salt uses many modules internally itself. At a bare minimum you need the following enabled or else the minion won't start. .. code-block:: yaml whitelist_modules: - cmdmod - test - config .. conf_minion:: module_dirs ``module_dirs`` --------------- Default: ``[]`` A list of extra directories to search for Salt modules .. code-block:: yaml module_dirs: - /var/lib/salt/modules .. conf_minion:: returner_dirs ``returner_dirs`` ----------------- Default: ``[]`` A list of extra directories to search for Salt returners .. code-block:: yaml returner_dirs: - /var/lib/salt/returners .. conf_minion:: states_dirs ``states_dirs`` --------------- Default: ``[]`` A list of extra directories to search for Salt states .. code-block:: yaml states_dirs: - /var/lib/salt/states .. conf_minion:: grains_dirs ``grains_dirs`` --------------- Default: ``[]`` A list of extra directories to search for Salt grains .. code-block:: yaml grains_dirs: - /var/lib/salt/grains .. conf_minion:: render_dirs ``render_dirs`` --------------- Default: ``[]`` A list of extra directories to search for Salt renderers .. code-block:: yaml render_dirs: - /var/lib/salt/renderers .. conf_minion:: utils_dirs ``utils_dirs`` -------------- Default: ``[]`` A list of extra directories to search for Salt utilities .. code-block:: yaml utils_dirs: - /var/lib/salt/utils .. conf_minion:: cython_enable ``cython_enable`` ----------------- Default: ``False`` Set this value to true to enable auto-loading and compiling of ``.pyx`` modules, This setting requires that ``gcc`` and ``cython`` are installed on the minion. .. code-block:: yaml cython_enable: False .. conf_minion:: enable_zip_modules ``enable_zip_modules`` ---------------------- .. versionadded:: 2015.8.0 Default: ``False`` Set this value to true to enable loading of zip archives as extension modules. This allows for packing module code with specific dependencies to avoid conflicts and/or having to install specific modules' dependencies in system libraries. .. code-block:: yaml enable_zip_modules: False .. conf_minion:: providers ``providers`` ------------- Default: (empty) A module provider can be statically overwritten or extended for the minion via the ``providers`` option. This can be done :ref:`on an individual basis in an SLS file `, or globally here in the minion config, like below. .. code-block:: yaml providers: service: systemd .. conf_minion:: modules_max_memory ``modules_max_memory`` ---------------------- Default: ``-1`` Specify a max size (in bytes) for modules on import. This feature is currently only supported on \*NIX operating systems and requires psutil. .. code-block:: yaml modules_max_memory: -1 .. conf_minion:: extmod_whitelist .. conf_minion:: extmod_blacklist ``extmod_whitelist/extmod_blacklist`` ------------------------------------- .. versionadded:: 2017.7.0 By using this dictionary, the modules that are synced to the minion'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: - beacons - clouds - sdb - modules - states - grains - renderers - returners - proxy - engines - output - utils - pillar Top File Settings ================= These parameters only have an effect if running a masterless minion. .. conf_minion:: 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. .. code-block:: yaml state_top: top.sls .. conf_minion:: 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_minion:`top_file_merging_strategy` is set to ``merge``, and :conf_minion:`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_minion:`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_minion:`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_minion:`top_file_merging_strategy` to ``merge_all``. .. code-block:: yaml state_top_saltenv: dev .. conf_minion:: 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_minion:`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_minion:`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_minion:`env_order`. .. code-block:: yaml top_file_merging_strategy: same .. conf_minion:: env_order ``env_order`` ------------- Default: ``[]`` When :conf_minion:`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_minion:: default_top ``default_top`` --------------- Default: ``base`` When :conf_minion:`top_file_merging_strategy` is set to ``same``, and no environment is specified for a :ref:`highstate ` (i.e. :conf_minion:`environment` is not set for the minion), this config option specifies a fallback environment in which to look for a top file if an environment lacks one. .. code-block:: yaml default_top: dev .. conf_minion:: startup_states ``startup_states`` ------------------ Default: ``''`` States to run when the minion daemon starts. To enable, set ``startup_states`` to: - ``highstate``: Execute state.highstate - ``sls``: Read in the sls_list option and execute the named sls files - ``top``: Read top_file option and execute based on that file on the Master .. code-block:: yaml startup_states: '' .. conf_minion:: sls_list ``sls_list`` ------------ Default: ``[]`` List of states to run when the minion starts up if ``startup_states`` is set to ``sls``. .. code-block:: yaml sls_list: - edit.vim - hyper .. conf_minion:: top_file ``top_file`` ------------ Default: ``''`` Top file to execute if ``startup_states`` is set to ``top``. .. code-block:: yaml top_file: '' State Management Settings ========================= .. conf_minion:: renderer ``renderer`` ------------ Default: ``jinja|yaml`` The default renderer used for local state executions .. code-block:: yaml renderer: jinja|json .. conf_minion:: test ``test`` -------- Default: ``False`` Set all state calls to only test if they are going to actually make changes or just post what changes are going to be made. .. code-block:: yaml test: False .. conf_minion:: 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: True .. conf_minion:: 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_minion:: 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_minion:: autoload_dynamic_modules ``autoload_dynamic_modules`` ---------------------------- Default: ``True`` autoload_dynamic_modules turns on automatic loading of modules found in the environments on the master. This is turned on by default. To turn off auto-loading modules when states run, set this value to ``False``. .. code-block:: yaml autoload_dynamic_modules: True .. conf_minion:: clean_dynamic_modules Default: ``True`` clean_dynamic_modules keeps the dynamic modules on the minion in sync with the dynamic modules on the master. This means that if a dynamic module is not on the master it will be deleted from the minion. By default this is enabled and can be disabled by changing this value to ``False``. .. code-block:: yaml clean_dynamic_modules: True .. note:: If ``extmod_whitelist`` is specified, modules which are not whitelisted will also be cleaned here. .. conf_minion:: environment .. conf_minion:: saltenv ``saltenv`` ----------- .. versionchanged:: 2018.3.0 Renamed from ``environment`` to ``saltenv``. If ``environment`` is used, ``saltenv`` will take its value. If both are used, ``environment`` will be ignored and ``saltenv`` will be used. Normally the minion is not isolated to any single environment on the master when running states, but the environment can be isolated on the minion side by statically setting it. Remember that the recommended way to manage environments is to isolate via the top file. .. code-block:: yaml saltenv: dev .. conf_minion:: lock_saltenv ``lock_saltenv`` ---------------- .. versionadded:: 2018.3.0 Default: ``False`` For purposes of running states, this option prevents using the ``saltenv`` argument to manually set the environment. This is useful to keep a minion which has the :conf_minion:`saltenv` option set to ``dev`` from running states from an environment other than ``dev``. .. code-block:: yaml lock_saltenv: True .. conf_minion:: snapper_states ``snapper_states`` ------------------ Default: False The `snapper_states` value is used to enable taking snapper snapshots before and after salt state runs. This allows for state runs to be rolled back. For snapper states to function properly snapper needs to be installed and enabled. .. code-block:: yaml snapper_states: True .. conf_minion:: snapper_states_config ``snapper_states_config`` ------------------------- Default: ``root`` Snapper can execute based on a snapper configuration. The configuration needs to be set up before snapper can use it. The default configuration is ``root``, this default makes snapper run on SUSE systems using the default configuration set up at install time. .. code-block:: yaml snapper_states_config: root File Directory Settings ======================= .. conf_minion:: file_client ``file_client`` --------------- Default: ``remote`` The client defaults to looking on the master server for files, but can be directed to look on the minion by setting this parameter to ``local``. .. code-block:: yaml file_client: remote .. conf_minion:: use_master_when_local ``use_master_when_local`` ------------------------- Default: ``False`` When using a local :conf_minion:`file_client`, this parameter is used to allow the client to connect to a master for remote execution. .. code-block:: yaml use_master_when_local: False .. conf_minion:: file_roots ``file_roots`` -------------- Default: .. code-block:: yaml base: - /srv/salt When using a local :conf_minion:`file_client`, this parameter is used to setup the fileserver's environments. This parameter operates identically to the :conf_master:`master config parameter ` of the same name. .. 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 .. conf_minion:: 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_minion:: 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_minion:: fileserver_limit_traversal ``fileserver_limit_traversal`` ------------------------------ .. versionadded:: 2014.1.0 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_minion:: hash_type ``hash_type`` ------------- Default: ``sha256`` The hash_type is the hash to use when discovering the hash of a file on the local fileserver. The default is sha256, but md5, sha1, sha224, sha384, and sha512 are also supported. .. code-block:: yaml hash_type: sha256 .. _pillar-configuration-minion: Pillar Configuration ==================== .. conf_minion:: pillar_roots ``pillar_roots`` ---------------- Default: .. code-block:: yaml base: - /srv/pillar When using a local :conf_minion:`file_client`, this parameter is used to setup the pillar environments. .. code-block:: yaml pillar_roots: base: - /srv/pillar dev: - /srv/pillar/dev prod: - /srv/pillar/prod .. conf_minion:: on_demand_ext_pillar ``on_demand_ext_pillar`` ------------------------ .. versionadded:: 2016.3.6,2016.11.3,2017.7.0 Default: ``['libvirt', 'virtkey']`` When using a local :conf_minion:`file_client`, this option controls which external pillars are 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 a masterless minion 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_minion:: 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_minion:`decrypt_pillar_default` will be used. .. conf_minion:: decrypt_pillar_delimiter ``decrypt_pillar_delimiter`` ---------------------------- .. versionadded:: 2017.7.0 Default: ``:`` The delimiter used to distinguish nested data structures in the :conf_minion:`decrypt_pillar` option. .. code-block:: yaml decrypt_pillar_delimiter: '|' decrypt_pillar: - 'foo|bar': gpg - 'lorem|ipsum|dolor' .. conf_minion:: 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_minion:`decrypt_pillar`. .. code-block:: yaml decrypt_pillar_default: my_custom_renderer .. conf_minion:: 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_minion:: pillarenv ``pillarenv`` ------------- Default: ``None`` Isolates the pillar environment on the minion side. This functions the same as the environment setting, but for pillar instead of states. .. code-block:: yaml pillarenv: dev .. conf_minion:: pillarenv_from_saltenv ``pillarenv_from_saltenv`` -------------------------- .. versionadded:: 2017.7.0 Default: ``False`` When set to ``True``, the :conf_minion:`pillarenv` value will assume the value of the effective saltenv when running states. This essentially makes ``salt '*' state.sls mysls saltenv=dev`` equivalent to ``salt '*' state.sls mysls saltenv=dev pillarenv=dev``. If :conf_minion:`pillarenv` is set, either in the minion config file or via the CLI, it will override this option. .. code-block:: yaml pillarenv_from_saltenv: True .. conf_minion:: 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. .. conf_minion:: minion_pillar_cache ``minion_pillar_cache`` ----------------------- .. versionadded:: 2016.3.0 Default: ``False`` The minion can locally cache rendered pillar data under :conf_minion:`cachedir`/pillar. This allows a temporarily disconnected minion to access previously cached pillar data by invoking salt-call with the --local and --pillar_root=:conf_minion:`cachedir`/pillar options. Before enabling this setting consider that the rendered pillar may contain security sensitive data. Appropriate access restrictions should be in place. By default the saved pillar data will be readable only by the user account running salt. By default this feature is disabled, to enable set minion_pillar_cache to ``True``. .. code-block:: yaml minion_pillar_cache: False .. conf_minion:: 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_minion:: pass_to_ext_pillars ``pass_to_ext_pillars`` ----------------------- Specify a list of configuration keys whose values are to be passed to external pillar functions. Suboptions can be specified using the ':' notation (i.e. ``option:suboption``) The values are merged and included in the ``extra_minion_data`` optional parameter of the external pillar function. The ``extra_minion_data`` parameter is passed only to the external pillar functions that have it explicitly specified in their definition. If the config contains .. code-block:: yaml opt1: value1 opt2: subopt1: value2 subopt2: value3 pass_to_ext_pillars: - opt1 - opt2: subopt1 the ``extra_minion_data`` parameter will be .. code-block:: python {'opt1': 'value1', 'opt2': {'subopt1': 'value2'}} Security Settings ================= .. conf_minion:: open_mode ``open_mode`` ------------- Default: ``False`` Open mode can be used to clean out the PKI key received from the Salt master, turn on open mode, restart the minion, then turn off open mode and restart the minion to clean the keys. .. code-block:: yaml open_mode: False .. conf_minion:: master_finger ``master_finger`` ----------------- Default: ``''`` Fingerprint of the master public key to validate the identity of your Salt master before the initial key exchange. The master fingerprint can be found by running "salt-key -F master" on the Salt master. .. code-block:: yaml master_finger: 'ba:30:65:2a:d6:9e:20:4f:d8:b2:f3:a7:d4:65:11:13' .. conf_minion:: keysize ``keysize`` ----------- Default: ``2048`` The size of key that should be generated when creating new keys. .. code-block:: yaml keysize: 2048 .. conf_minion:: 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. .. code-block:: yaml permissive_pki_access: False .. conf_minion:: verify_master_pubkey_sign ``verify_master_pubkey_sign`` ----------------------------- Default: ``False`` Enables verification of the master-public-signature returned by the master in auth-replies. Please see the tutorial on how to configure this properly `Multimaster-PKI with Failover Tutorial `_ .. versionadded:: 2014.7.0 .. code-block:: yaml verify_master_pubkey_sign: True If this is set to ``True``, :conf_master:`master_sign_pubkey` must be also set to ``True`` in the master configuration file. .. conf_minion:: master_sign_key_name ``master_sign_key_name`` ------------------------ Default: ``master_sign`` The filename without the *.pub* suffix of the public key that should be used for verifying the signature from the master. The file must be located in the minion's pki directory. .. versionadded:: 2014.7.0 .. code-block:: yaml master_sign_key_name: .. conf_minion:: autosign_grains ``autosign_grains`` ------------------- .. versionadded:: 2018.3.0 Default: ``not defined`` The grains that should be sent to the master on authentication to decide if the minion's key should be accepted automatically. Please see the :ref:`Autoaccept Minions from Grains ` documentation for more information. .. code-block:: yaml autosign_grains: - uuid - server_id .. conf_minion:: always_verify_signature ``always_verify_signature`` --------------------------- Default: ``False`` If :conf_minion:`verify_master_pubkey_sign` is enabled, the signature is only verified if the public-key of the master changes. If the signature should always be verified, this can be set to ``True``. .. versionadded:: 2014.7.0 .. code-block:: yaml always_verify_signature: True .. conf_minion:: cmd_blacklist_glob ``cmd_blacklist_glob`` ---------------------- Default: ``[]`` If :conf_minion:`cmd_blacklist_glob` is enabled then any shell command called over remote execution or via salt-call will be checked against the glob matches found in the `cmd_blacklist_glob` list and any matched shell command will be blocked. .. note:: This blacklist is only applied to direct executions made by the `salt` and `salt-call` commands. This does NOT blacklist commands called from states or shell commands executed from other modules. .. versionadded:: 2016.11.0 .. code-block:: yaml cmd_blacklist_glob: - 'rm * ' - 'cat /etc/* ' .. conf_minion:: cmd_whitelist_glob ``cmd_whitelist_glob`` ---------------------- Default: ``[]`` If :conf_minion:`cmd_whitelist_glob` is enabled then any shell command called over remote execution or via salt-call will be checked against the glob matches found in the `cmd_whitelist_glob` list and any shell command NOT found in the list will be blocked. If `cmd_whitelist_glob` is NOT SET, then all shell commands are permitted. .. note:: This whitelist is only applied to direct executions made by the `salt` and `salt-call` commands. This does NOT restrict commands called from states or shell commands executed from other modules. .. versionadded:: 2016.11.0 .. code-block:: yaml cmd_whitelist_glob: - 'ls * ' - 'cat /etc/fstab' .. conf_minion:: 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 Reactor Settings ================ .. conf_minion:: reactor ``reactor`` ----------- Default: ``[]`` Defines a salt reactor. See the :ref:`Reactor ` documentation for more information. .. code-block:: yaml reactor: [] .. conf_minion:: 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_minion:: 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_minion:: reactor_worker_hwm ``reactor_worker_hwm`` ---------------------- Default: ``10000`` The queue size for workers in the reactor. .. code-block:: yaml reactor_worker_hwm: 10000 Thread Settings =============== .. conf_minion:: multiprocessing ``multiprocessing`` ------------------- Default: ``True`` If ``multiprocessing`` is enabled when a minion receives a publication a new process is spawned and the command is executed therein. Conversely, if ``multiprocessing`` is disabled the new publication will be run executed in a thread. .. code-block:: yaml multiprocessing: True .. conf_minion:: process_count_max ``process_count_max`` --------------------- .. versionadded:: 2018.3.0 Default: ``-1`` Limit the maximum amount of processes or threads created by ``salt-minion``. This is useful to avoid resource exhaustion in case the minion receives more publications than it is able to handle, as it limits the number of spawned processes or threads. ``-1`` is the default and disables the limit. .. code-block:: yaml process_count_max: -1 .. _minion-logging-settings: Minion Logging Settings ======================= .. conf_minion:: log_file ``log_file`` ------------ Default: ``/var/log/salt/minion`` The minion 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/minion .. code-block:: yaml log_file: file:///dev/log .. code-block:: yaml log_file: udp://loghost:10514 .. conf_minion:: 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_minion:: 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_minion:: 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_minion:: 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_minion:: 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_minion:`color` config since the logging system is loaded before the minion 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_minion:: 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_minion:: 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_minion:: 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_minion:: 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_minion:`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` .. conf_minion:: zmq_monitor ``zmq_monitor`` --------------- Default: ``False`` To diagnose issues with minions disconnecting or missing returns, ZeroMQ supports the use of monitor sockets to log connection events. This feature requires ZeroMQ 4.0 or higher. To enable ZeroMQ monitor sockets, set 'zmq_monitor' to 'True' and log at a debug level or higher. A sample log event is as follows: .. code-block:: yaml [DEBUG ] ZeroMQ event: {'endpoint': 'tcp://127.0.0.1:4505', 'event': 512, 'value': 27, 'description': 'EVENT_DISCONNECTED'} All events logged will include the string ``ZeroMQ event``. A connection event should be logged as the minion starts up and initially connects to the master. If not, check for debug log level and that the necessary version of ZeroMQ is installed. .. conf_minion:: failhard ``tcp_authentication_retries`` ------------------------------ Default: ``5`` The number of times to retry authenticating with the salt master when it comes back online. Zeromq does a lot to make sure when connections come back online that they reauthenticate. The tcp transport should try to connect with a new connection if the old one times out on reauthenticating. `-1` for infinite tries. ``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 Include Configuration ===================== Configuration can be loaded from multiple files. The order in which this is done is: 1. The minion config file itself 2. The files matching the glob in :conf_minion:`default_include` 3. The files matching the glob in :conf_minion:`include` (if defined) Each successive step overrides any values defined in the previous steps. Therefore, any config options defined in one of the :conf_minion:`default_include` files would override the same value in the minion config file, and any options defined in :conf_minion:`include` would override both. .. conf_minion:: default_include ``default_include`` ------------------- Default: ``minion.d/*.conf`` The minion can include configuration from other files. Per default the minion will automatically include all config files from `minion.d/*.conf` where minion.d is relative to the directory of the minion configuration file. .. note:: Salt creates files in the ``minion.d`` directory for its own use. These files are prefixed with an underscore. A common example of this is the ``_schedule.conf`` file. .. conf_minion:: include ``include`` ----------- Default: ``not defined`` The minion 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 minion will log a warning message. .. code-block:: yaml # Include files from a minion.d directory in the same # directory as the minion config file include: minion.d/*.conf # Include a single extra file into the configuration include: /etc/roles/webserver # Include several files and the minion.d directory include: - extra_config - minion.d/* - /etc/roles/webserver Keepalive Settings ================== .. conf_minion:: 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_minion:: 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_minion:: 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_minion:: 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 Frozen Build Update Settings ============================ These options control how :py:func:`salt.modules.saltutil.update` works with esky frozen apps. For more information look at ``_. .. conf_minion:: update_url ``update_url`` -------------- Default: ``False`` (Update feature is disabled) The url to use when looking for application updates. Esky depends on directory listings to search for new versions. A webserver running on your Master is a good starting point for most setups. .. code-block:: yaml update_url: 'http://salt.example.com/minion-updates' .. conf_minion:: update_restart_services ``update_restart_services`` --------------------------- Default: ``[]`` (service restarting on update is disabled) A list of services to restart when the minion software is updated. This would typically just be a list containing the minion's service name, but you may have other services that need to go with it. .. code-block:: yaml update_restart_services: ['salt-minion'] .. conf_minion:: winrepo_cache_expire_min ``winrepo_cache_expire_min`` ---------------------------- .. versionadded:: 2016.11.0 Default: ``1800`` If set to a nonzero integer, then passing ``refresh=True`` to functions in the :mod:`windows pkg module ` will not refresh the windows repo metadata if the age of the metadata is less than this value. The exception to this is :py:func:`pkg.refresh_db `, which will always refresh the metadata, regardless of age. .. code-block:: yaml winrepo_cache_expire_min: 1800 .. conf_minion:: winrepo_cache_expire_max ``winrepo_cache_expire_max`` ---------------------------- .. versionadded:: 2016.11.0 Default: ``21600`` If the windows repo metadata is older than this value, and the metadata is needed by a function in the :mod:`windows pkg module `, the metadata will be refreshed. .. code-block:: yaml winrepo_cache_expire_max: 86400 .. _winrepo-minion-config-opts: Minion Windows Software Repo Settings ===================================== .. important:: To use these config options, the minion can be running in master-minion or masterless mode. .. conf_minion:: winrepo_source_dir ``winrepo_source_dir`` ---------------------- Default: ``salt://win/repo-ng/`` The source location for the winrepo sls files. .. code-block:: yaml winrepo_source_dir: salt://win/repo-ng/ Standalone Minion Windows Software Repo Settings ================================================ .. important:: To use these config options, the minion must be running in masterless mode (set :conf_minion:`file_client` to ``local``). .. conf_minion:: winrepo_dir .. conf_minion:: win_repo ``winrepo_dir`` --------------- .. versionchanged:: 2015.8.0 Renamed from ``win_repo`` to ``winrepo_dir``. Also, this option did not have a default value until this version. Default: ``C:\salt\srv\salt\win\repo`` Location on the minion where the :conf_minion:`winrepo_remotes` are checked out. .. code-block:: yaml winrepo_dir: 'D:\winrepo' .. conf_minion:: 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 minion where the :conf_minion:`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_minion:: winrepo_cachefile .. conf_minion:: win_repo_cachefile ``winrepo_cachefile`` --------------------- .. versionchanged:: 2015.8.0 Renamed from ``win_repo_cachefile`` to ``winrepo_cachefile``. Also, this option did not have a default value until this version. Default: ``winrepo.p`` Path relative to :conf_minion:`winrepo_dir` where the winrepo cache should be created. .. code-block:: yaml winrepo_cachefile: winrepo.p .. conf_minion:: winrepo_remotes .. conf_minion:: win_gitrepos ``winrepo_remotes`` ------------------- .. versionchanged:: 2015.8.0 Renamed from ``win_gitrepos`` to ``winrepo_remotes``. Also, this option did not have a default value until this version. .. versionadded:: 2015.8.0 Default: ``['https://github.com/saltstack/salt-winrepo.git']`` List of git repositories to checkout and include in the winrepo .. 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_minion:: 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. ``ssh_merge_pillar`` -------------------- .. versionadded:: 2018.3.2 Default: ``True`` Merges the compiled pillar data with the pillar data already available globally. This is useful when using ``salt-ssh`` or ``salt-call --local`` and overriding the pillar data in a state file: .. code-block:: yaml apply_showpillar: module.run: - name: state.apply - mods: - showpillar - kwargs: pillar: test: "foo bar" If set to ``True`` the ``showpillar`` state will have access to the global pillar data. If set to ``False`` only the overriding pillar data will be available to the ``showpillar`` state.
