- .. _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 <configuration-examples-minion>`
- 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 <tutorial-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 <master-tops-system>` system
- are normally executed *after* any matches defined in the :ref:`Top File
- <states-top>`. Set this option to ``True`` to have the minion execute the
- :ref:`Master Tops <master-tops-system>` 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/<minion_id>/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/<minion_id>/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 <python2: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 <python2: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:

- .. 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: ``/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 <minion-id-generation>`
- 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_remove_domain
- ``minion_id_remove_domain``
- ---------------------------
- .. versionadded:: 3000
- Default: ``False``
- Remove a domain when the minion id is generated as a fully qualified domain
- name (either by the user provided ``id_function``, or by Salt). This is useful
- when the minions shall be named like hostnames. Can be a single domain (to
- prevent name clashes), or True, to remove all domains.
- Examples:
- - minion_id_remove_domain = foo.org
- - FQDN = king_bob.foo.org --> minion_id = king_bob
- - FQDN = king_bob.bar.org --> minion_id = king_bob.bar.org
- - minion_id_remove_domain = True
- - FQDN = king_bob.foo.org --> minion_id = king_bob
- - FQDN = king_bob.bar.org --> minion_id = king_bob
- For more information, please see :issue:`49212` and :pull:`49378`.
- .. code-block:: yaml
- minion_id_remove_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 <salt.modules.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:: 3000
- .. 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
- <salt.grains.metadata>` 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 <salt-mine>` for more information.
- Note these can be defined in the pillar for a minion as well.
- :ref:`example minion configuration file <configuration-examples-minion>`
- .. 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 <file-state-backups>` 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'

- 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:: 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' ]
- ``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 <release-2019-2-1>` for more details.

- 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 <salt-mine>` will be updated with the results of :py:func:`docker.ps
- verbose=True all=True host=True <salt.modules.dockermod.ps>`. This mine data is
- used by :py:func:`mine.get_docker <salt.modules.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
- <salt.modules.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
- <salt.modules.dockermod.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:

- .. 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 <state-providers>`, 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

- 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 <running-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 <running-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 <running-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 <running-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:: start_event_grains
- ``start_event_grains``
- ----------------------
- Default: ``[]``
- List of grains to pass in start event when minion starts up.
- .. code-block:: yaml
- start_event_grains:
- - machine_id
- - uuid
- .. 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 <file_roots>` 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
- <salt.modules.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 <salt.modules.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 <pillar-in-memory>`, 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
- <salt.modules.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 <http://docs.saltstack.com/en/latest/topics/tutorials/multimaster_pki.html>`_
- .. 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: <filename_without_suffix>
- .. 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 <tutorial-autoaccept-grains>`
- documentation for more information.
- .. code-block:: yaml
- autosign_grains:
- - uuid

- ``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,

- .. 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/* '

- ``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

- arguments corresponding to python ``ssl.wrap_socket`` method. For details see
- `Tornado <http://www.tornadoweb.org/en/stable/tcpserver.html#tornado.tcpserver.TCPServer>`_
- and `Python <http://docs.python.org/2/library/ssl.html#ssl.wrap_socket>`_
- 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: <path_to_keyfile>

- 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 `<https://github.com/cloudmatrix/esky/>`_.
- .. 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 <salt.modules.win_pkg>` 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 <salt.modules.win_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 <salt.modules.win_pkg>`,
- the metadata will be refreshed.
- .. code-block:: yaml
- winrepo_cache_expire_max: 86400
- .. _winrepo-minion-config-opts:
- Minion Windows Software Repo Settings

- .. 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 <windows-package-manager>` repo was added.

- URL of the repository:
- .. code-block:: yaml
- winrepo_remotes:
- - '<commit_id> https://github.com/saltstack/salt-winrepo.git'
- Replace ``<commit_id>`` 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 <windows-package-manager>` repo was added.

- ``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

- 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
