===========================
Configuring the Salt Master
===========================
The Salt system is amazingly simple and easy to configure, the two components
of the Salt system each have a respective configuration file. The
: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 master configuration file <configuration-examples-master>`
The configuration file for the salt-master is located at
:file:`/etc/salt/master` by default. A notable exception is FreeBSD, where the
configuration file is located at :file:`/usr/local/etc/salt`. The available
options are as follows:
Primary Master Configuration
============================
.. conf_master:: interface
``interface``
-------------
Default: ``0.0.0.0`` (all interfaces)
The local interface to bind to.
.. code-block:: yaml
interface: 192.168.0.1
.. conf_master:: ipv6
``ipv6``
--------
Default: ``False``
Whether the master should listen for IPv6 connections. If this is set to True,
the interface option must be adjusted too (for example: "interface: '::'")
.. code-block:: yaml
ipv6: True
.. conf_master:: publish_port
``publish_port``
----------------
Default: ``4505``
The network port to set up the publication interface
.. code-block:: yaml
publish_port: 4505
.. conf_master:: master_id
``master_id``
----------------
Default: ``None``
The id to be passed in the publish job to minions. This is used for MultiSyndics
to return the job to the requesting master. Note, this must be the same string
as the syndic is configured with.
.. code-block:: yaml
master_id: MasterOfMaster
.. conf_master:: user
``user``
--------
Default: ``root``
The user to run the Salt processes
.. code-block:: yaml
user: root
.. conf_master:: max_open_files
``max_open_files``
------------------
Default: ``100000``
Each minion connecting to the master uses AT LEAST one file descriptor, the
master subscription connection. If enough minions connect you might start
seeing on the console(and then salt-master crashes):
.. code-block:: bash
Too many open files (tcp_listener.cpp:335)
Aborted (core dumped)
.. code-block:: yaml
max_open_files: 100000
By default this value will be the one of `ulimit -Hn`, i.e., the hard limit for
max open files.
To set a different value than the default one, uncomment and configure this
setting. Remember that this value CANNOT be higher than the hard limit. Raising
the hard limit depends on the OS and/or distribution, a good way to find the
limit is to search the internet for something like this:
.. code-block:: text
raise max open files hard limit debian
.. conf_master:: worker_threads
``worker_threads``
------------------
Default: ``5``
The number of threads to start for receiving commands and replies from minions.
If minions are stalling on replies because you have many minions, raise the
worker_threads value.
Worker threads should not be put below 3 when using the peer system, but can
drop down to 1 worker otherwise.
.. code-block:: yaml
worker_threads: 5
.. conf_master:: ret_port
``ret_port``
------------
Default: ``4506``
The port used by the return server, this is the server used by Salt to receive
execution returns and command executions.
.. code-block:: yaml
ret_port: 4506
.. conf_master:: pidfile
``pidfile``
-----------
Default: ``/var/run/salt-master.pid``
Specify the location of the master pidfile
.. code-block:: yaml
pidfile: /var/run/salt-master.pid
.. conf_master:: root_dir
``root_dir``
------------
Default: :file:`/`
The system root directory to operate from, change this to make Salt run from
an alternative root.
.. code-block:: yaml
root_dir: /
.. note::
This directory is prepended to the following options:
:conf_master:`pki_dir`, :conf_master:`cachedir`, :conf_master:`sock_dir`,
:conf_master:`log_file`, :conf_master:`autosign_file`,
:conf_master:`autoreject_file`, :conf_master:`pidfile`.
.. conf_master:: pki_dir
``pki_dir``
-----------
Default: :file:`/etc/salt/pki`
The directory to store the pki authentication keys.
.. code-block:: yaml
pki_dir: /etc/salt/pki
.. conf_master:: extension_modules
``extension_modules``
---------------------
Directory for custom modules. This directory can contain subdirectories for
each of Salt's module types such as "runners", "output", "wheel", "modules",
"states", "returners", etc. This path is appended to :conf_master:`root_dir`.
.. code-block:: yaml
extension_modules: srv/modules
.. conf_master:: cachedir
``cachedir``
------------
Default: :file:`/var/cache/salt`
The location used to store cache information, particularly the job information
for executed salt commands.
.. code-block:: yaml
cachedir: /var/cache/salt
.. conf_master:: verify_env
``verify_env``
--------------
Default: ``True``
Verify and set permissions on configuration directories at startup.
.. code-block:: yaml
verify_env: True
.. conf_master:: keep_jobs
``keep_jobs``
-------------
Default: ``24``
Set the number of hours to keep old job information
.. conf_master:: timeout
``timeout``
-----------
Default: ``5``
Set the default timeout for the salt command and api.
.. conf_master:: loop_interval
``loop_interval``
-----------------
Default: ``60``
The loop_interval option controls the seconds for the master's maintenance
process check cycle. This process updates file server backends, cleans the
job cache and executes the scheduler.
.. conf_master:: output
``output``
----------
Default: ``nested``
Set the default outputter used by the salt command.
.. conf_master:: color
``color``
---------
Default: ``True``
By default output is colored, to disable colored output set the color value
to False
.. code-block:: yaml
color: False
.. conf_master:: sock_dir
``sock_dir``
------------
Default: :file:`/var/run/salt/master`
Set the location to use for creating Unix sockets for master process
communication
.. code-block:: yaml
sock_dir: /var/run/salt/master
.. conf_master:: enable_gpu_grains
``enable_gpu_grains``
---------------------
Default: ``False``
The master can take a while to start up when lspci and/or dmidecode is used
to populate the grains for the master. Enable if you want to see GPU hardware
data for your master.
.. conf_master:: job_cache
``job_cache``
-------------
Default: ``True``
The master maintains a job cache, while this is a great addition it can be
a burden on the master for larger deployments (over 5000 minions).
Disabling the job cache will make previously executed jobs unavailable to
the jobs system and is not generally recommended. Normally it is wise to make
sure the master has access to a faster IO system or a tmpfs is mounted to the
jobs dir
.. conf_master:: minion_data_cache
``minion_data_cache``
---------------------
Default: ``True``
The minion data cache is a cache of information about the minions stored on the
master, this information is primarily the pillar and grains data. The data is
cached in the Master cachedir under the name of the minion and used to pre
determine what minions are expected to reply from executions.
.. code-block:: yaml
minion_data_cache: True
.. conf_master:: ext_job_cache
``ext_job_cache``
-----------------
Default: ``''``
Used to specify a default returner for all minions, when this option is set
the specified returner needs to be properly configured and the minions will
always default to sending returns to this returner. This will also disable the
local job cache on the master
.. code-block:: yaml
ext_job_cache: redis
.. conf_master:: enforce_mine_cache
``enforce_mine_cache``
----------------------
Default: False
By-default when disabling the minion_data_cache mine will stop working since
it is based on cached data, by enabling this option we explicitly enabling
only the cache for the mine system.
.. code-block:: yaml
enforce_mine_cache: False
``max_minions``
---------------
Default: 0
The number of minions the master should allow to connect. Use this to accommodate
the number of minions per master if you have different types of hardware serving
your minions. The default of ``0`` means unlimited connections. Please note, that
this can slow down the authentication process a bit in large setups.
.. code-block:: yaml
max_minions: 100
``presence_events``
----------------------
Default: False
When enabled the master regularly sends events of currently connected, lost
and newly connected minions on the eventbus.
.. code-block:: yaml
presence_events: False
Master Security Settings
========================
.. conf_master:: open_mode
``open_mode``
-------------
Default: ``False``
Open mode is a dangerous security feature. One problem encountered with pki
authentication systems is that keys can become "mixed up" and authentication
begins to fail. Open mode turns off authentication and tells the master to
accept all authentication. This will clean up the pki keys received from the
minions. Open mode should not be turned on for general use. Open mode should
only be used for a short period of time to clean up pki keys. To turn on open
mode set this value to ``True``.
.. code-block:: yaml
open_mode: False
.. conf_master:: auto_accept
``auto_accept``
---------------
Default: ``False``
Enable auto_accept. This setting will automatically accept all incoming
public keys from minions.
.. code-block:: yaml
auto_accept: False
.. conf_master:: autosign_timeout
``autosign_timeout``
--------------------
.. versionadded:: 2014.7.0
Default: ``120``
Time in minutes that a incoming public key with a matching name found in
pki_dir/minion_autosign/keyid is automatically accepted. Expired autosign keys
are removed when the master checks the minion_autosign directory. This method
to auto accept minions can be safer than an autosign_file because the
keyid record can expire and is limited to being an exact name match.
This should still be considered a less than secure option, due to the fact
that trust is based on just the requesting minion id.
.. conf_master:: autosign_file
``autosign_file``
-----------------
Default: ``not defined``
If the ``autosign_file`` is specified incoming keys specified in the autosign_file
will be automatically accepted. Matches will be searched for first by string
comparison, then by globbing, then by full-string regex matching.
This should still be considered a less than secure option, due to the fact
that trust is based on just the requesting minion id.
.. conf_master:: autoreject_file
``autoreject_file``
-------------------
.. versionadded:: 2014.1.0
Default: ``not defined``
Works like :conf_master:`autosign_file`, but instead allows you to specify
minion IDs for which keys will automatically be rejected. Will override both
membership in the :conf_master:`autosign_file` and the
:conf_master:`auto_accept` setting.
.. conf_master:: client_acl
``client_acl``
--------------
Default: ``{}``
Enable user accounts on the master to execute specific modules. These modules
can be expressed as regular expressions
.. code-block:: yaml
client_acl:
fred:
- test.ping
- pkg.*
.. conf_master:: client_acl_blacklist
``client_acl_blacklist``
------------------------
Default: ``{}``
Blacklist users or modules
This example would blacklist all non sudo users, including root from
running any commands. It would also blacklist any use of the "cmd"
module.
This is completely disabled by default.
.. code-block:: yaml
client_acl_blacklist:
users:
- root
- '^(?!sudo_).*$' # all non sudo users
modules:
- cmd
.. conf_master:: external_auth
``external_auth``
-----------------
Default: ``{}``
The external auth system uses the Salt auth modules to authenticate and
validate users to access areas of the Salt system.
.. code-block:: yaml
external_auth:
pam:
fred:
- test.*
.. conf_master:: token_expire
``token_expire``
----------------
Default: ``43200``
Time (in seconds) for a newly generated token to live. Default: 12 hours
.. code-block:: yaml
token_expire: 43200
.. conf_master:: file_recv
``file_recv``
-------------
Default: ``False``
Allow minions to push files to the master. This is disabled by default, for
security purposes.
.. code-block:: yaml
file_recv: False
.. conf_master:: master_sign_pubkey
``master_sign_pubkey``
----------------------
Default: ``False``
Sign the master auth-replies with a cryptographical signature of the masters
public key. Please see the tutorial how to use these settings in the
`Multimaster-PKI with Failover Tutorial <http://docs.saltstack.com/en/latest/topics/tutorials/multimaster_pki.html>`_
.. code-block:: yaml
master_sign_pubkey: True
.. conf_master:: master_sign_key_name
``master_sign_key_name``
-----------------------
Default: ``master_sign``
The customizable name of the signing-key-pair without suffix.
.. code-block:: yaml
master_sign_key_name: <filename_without_suffix>
.. conf_master:: master_pubkey_signature
``master_pubkey_signature``
---------------------------
Default: ``master_pubkey_signature``
The name of the file in the masters pki-directory that holds the pre-calculated
signature of the masters public-key.
.. code-block:: yaml
master_pubkey_signature: <filename>
.. conf_master:: master_use_pubkey_signature
``master_use_pubkey_signature``
-------------------------------
Default: ``False``
Instead of computing the signature for each auth-reply, use a pre-calculated
signature. The :conf_master:`master_pubkey_signature` must also be set for this.
.. code-block:: yaml
master_use_pubkey_signature: True
Master Module Management
========================
.. conf_master:: runner_dirs
``runner_dirs``
---------------
Default: ``[]``
Set additional directories to search for runner modules
.. conf_master:: cython_enable
``cython_enable``
-----------------
Default: ``False``
Set to true to enable Cython modules (.pyx files) to be compiled on the fly on
the Salt master
.. code-block:: yaml
cython_enable: False
Master State System Settings
============================
.. conf_master:: state_top
``state_top``
-------------
Default: ``top.sls``
The state system uses a "top" file to tell the minions what environment to
use and what modules to use. The state_top file is defined relative to the
root of the base environment
.. code-block:: yaml
state_top: top.sls
.. conf_master:: master_tops
``master_tops``
---------------
Default: ``{}``
The master_tops option replaces the external_nodes option by creating
a pluggable system for the generation of external top data. The external_nodes
option is deprecated by the master_tops option.
To gain the capabilities of the classic external_nodes system, use the
following configuration:
.. code-block:: yaml
master_tops:
ext_nodes: <Shell command which returns yaml>
.. conf_master:: external_nodes
``external_nodes``
------------------
Default: None
The external_nodes option allows Salt to gather data that would normally be
placed in a top file from and external node controller. The external_nodes
option is the executable that will return the ENC data. Remember that Salt
will look for external nodes AND top files and combine the results if both
are enabled and available!
.. code-block:: yaml
external_nodes: cobbler-ext-nodes
.. conf_master:: renderer
``renderer``
------------
Default: ``yaml_jinja``
The renderer to use on the minions to render the state data
.. code-block:: yaml
renderer: yaml_jinja
.. conf_master:: failhard
``failhard``
------------
Default: ``False``
Set the global failhard flag, this informs all states to stop running states
at the moment a single state fails
.. code-block:: yaml
failhard: False
.. conf_master:: state_verbose
``state_verbose``
-----------------
Default: ``True``
Controls the verbosity of state runs. By default, the results of all states are
returned, but setting this value to ``False`` will cause salt to only display
output for states which either failed, or succeeded without making any changes
to the minion.
.. code-block:: yaml
state_verbose: False
.. conf_master:: state_output
``state_output``
----------------
Default: ``full``
The state_output setting changes if the output is the full multi line
output for each changed state if set to 'full', but if set to 'terse'
the output will be shortened to a single line. If set to 'mixed', the output
will be terse unless a state failed, in which case that output will be full.
If set to 'changes', the output will be full unless the state didn't change.
.. code-block:: yaml
state_output: full
.. conf_master:: yaml_utf8
``yaml_utf8``
-------------
Default: ``False``
Enable extra routines for yaml renderer used states containing UTF characters
.. code-block:: yaml
yaml_utf8: False
.. conf_master:: 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
Master File Server Settings
===========================
.. conf_master:: fileserver_backend
``fileserver_backend``
----------------------
Default:
.. code-block:: yaml
fileserver_backend:
- roots
Salt supports a modular fileserver backend system, this system allows the salt
master to link directly to third party systems to gather and manage the files
available to minions. Multiple backends can be configured and will be searched
for the requested file in the order in which they are defined here. The default
setting only enables the standard backend ``roots``, which is configured using
the :conf_master:`file_roots` option.
Example:
.. code-block:: yaml
fileserver_backend:
- roots
- git
.. conf_master:: hash_type
``hash_type``
-------------
Default: ``md5``
The hash_type is the hash to use when discovering the hash of a file on
the master server. The default is md5, but sha1, sha224, sha256, sha384
and sha512 are also supported.
.. code-block:: yaml
hash_type: md5
.. conf_master:: file_buffer_size
``file_buffer_size``
--------------------
Default: ``1048576``
The buffer size in the file server in bytes
.. code-block:: yaml
file_buffer_size: 1048576
.. conf_master:: file_ignore_regex
``file_ignore_regex``
---------------------
Default: ``''``
A regular expression (or a list of expressions) that will be matched
against the file path before syncing the modules and states to the minions.
This includes files affected by the file.recurse state.
For example, if you manage your custom modules and states in subversion
and don't want all the '.svn' folders and content synced to your minions,
you could set this to '/\.svn($|/)'. By default nothing is ignored.
.. code-block:: yaml
file_ignore_regex:
- '/\.svn($|/)'
- '/\.git($|/)'
.. conf_master:: file_ignore_glob
``file_ignore_glob``
--------------------
Default ``''``
A file glob (or list of file globs) that will be matched against the file
path before syncing the modules and states to the minions. This is similar
to file_ignore_regex above, but works on globs instead of regex. By default
nothing is ignored.
.. code-block:: yaml
file_ignore_glob:
- '\*.pyc'
- '\*/somefolder/\*.bak'
- '\*.swp'
roots: Master's Local File Server
---------------------------------
.. conf_master:: file_roots
``file_roots``
**************
Default:
.. code-block:: yaml
base:
- /srv/salt
Salt runs a lightweight file server written in ZeroMQ to deliver files to
minions. This file server is built into the master daemon and does not
require a dedicated port.
The file server works on environments passed to the master. Each environment
can have multiple root directories. The subdirectories in the multiple file
roots cannot match, otherwise the downloaded files will not be able to be
reliably ensured. A base environment is required to house the top file.
Example:
.. code-block:: yaml
file_roots:
base:
- /srv/salt
dev:
- /srv/salt/dev/services
- /srv/salt/dev/states
prod:
- /srv/salt/prod/services
- /srv/salt/prod/states
git: Git Remote File Server Backend
-----------------------------------
.. conf_master:: gitfs_remotes
``gitfs_remotes``
*****************
Default: ``[]``
When using the ``git`` fileserver backend at least one git remote needs to be
defined. The user running the salt master will need read access to the repo.
The repos will be searched in order to find the file requested by a client and
the first repo to have the file will return it. Branches and tags are
translated into salt environments.
.. code-block:: yaml
gitfs_remotes:
- git://github.com/saltstack/salt-states.git
- file:///var/git/saltmaster
.. note::
``file://`` repos will be treated as a remote, so refs you want used must
exist in that repo as *local* refs.
.. note::
As of 2014.7.0, it is possible to have per-repo versions of the
:conf_master:`gitfs_base`, :conf_master:`gitfs_root`, and
:conf_master:`gitfs_mountpoint` parameters. For example:
.. code-block:: yaml
gitfs_remotes:
- https://foo.com/foo.git
- https://foo.com/bar.git:
- root: salt
- mountpoint: salt://foo/bar/baz
- base: salt-base
- https://foo.com/baz.git:
- root: salt/states
For more information on GitFS remotes, see the :ref:`GitFS Backend Walkthrough
<tutorial-gitfs>`.
.. conf_master:: gitfs_provider
``gitfs_provider``
******************
.. versionadded:: 2014.7.0
Default: ``gitpython``
GitFS defaults to using GitPython_, but this parameter allows for either
pygit2_ or dulwich_ to be used instead. If using pygit2, both libgit2 and git
itself must also be installed. More information can be found in the :mod:`GitFS
backend documentation <salt.fileserver.gitfs>` and the :doc:`GitFS walkthrough
</topics/tutorials/gitfs>`.
.. _GitPython: https://github.com/gitpython-developers/GitPython
.. _pygit2: https://github.com/libgit2/pygit2
.. _dulwich: https://www.samba.org/~jelmer/dulwich/
.. code-block:: yaml
gitfs_provider: pygit2
.. conf_master:: gitfs_ssl_verify
``gitfs_ssl_verify``
********************
Default: ``[]``
The ``gitfs_ssl_verify`` option specifies whether to ignore SSL certificate
errors when contacting the gitfs backend. You might want to set this to
false if you're using a git backend that uses a self-signed certificate but
keep in mind that setting this flag to anything other than the default of True
is a security concern, you may want to try using the ssh transport.
.. code-block:: yaml
gitfs_ssl_verify: True
.. conf_master:: gitfs_mountpoint
``gitfs_mountpoint``
********************
.. versionadded:: 2014.7.0
Default: ``''``
Specifies a path on the salt fileserver from which gitfs remotes are served.
Can be used in conjunction with :conf_master:`gitfs_root`. Can also be
configured on a per-remote basis, see :conf_master:`here <gitfs_remotes>` for
more info.
.. code-block:: yaml
gitfs_mountpoint: salt://foo/bar
.. note::
The ``salt://`` protocol designation can be left off (in other words,
``foo/bar`` and ``salt://foo/bar`` are equivalent).
.. conf_master:: gitfs_root
``gitfs_root``
**************
Default: ``''``
Serve files from a subdirectory within the repository, instead of the root.
This is useful when there are files in the repository that should not be
available to the Salt fileserver. Can be used in conjunction with
:conf_master:`gitfs_mountpoint`.
.. code-block:: yaml
gitfs_root: somefolder/otherfolder
.. versionchanged:: 2014.7.0
Ability to specify gitfs roots on a per-remote basis was added. See
:conf_master:`here <gitfs_remotes>` for more info.
.. conf_master:: gitfs_base
``gitfs_base``
**************
Default: ``master``
Defines which branch/tag should be used as the ``base`` environment.
.. versionchanged:: 2014.7.0
Can also be configured on a per-remote basis, see :conf_master:`here
<gitfs_remotes>` for more info.
.. code-block:: yaml
gitfs_base: salt
.. conf_master:: gitfs_env_whitelist
``gitfs_env_whitelist``
***********************
.. versionadded:: 2014.7.0
Default: ``[]``
Used to restrict which environments are made available. Can speed up state runs
if your gitfs remotes contain many branches/tags. Full names, globs, and
regular expressions are supported. If using a regular expression, the
expression must match the entire minion ID.
If used, only branches/tags/SHAs which match one of the specified expressions
will be exposed as fileserver environments.
If used in conjunction with :conf_master:`gitfs_env_blacklist`, then the subset
of branches/tags/SHAs which match the whitelist but do *not* match the
blacklist will be exposed as fileserver environments.
.. code-block:: yaml
gitfs_env_whitelist:
- base
- v1.*
- 'mybranch\d+'
.. conf_master:: gitfs_env_blacklist
``gitfs_env_blacklist``
***********************
.. versionadded:: 2014.7.0
Default: ``[]``
Used to restrict which environments are made available. Can speed up state runs
if your gitfs remotes contain many branches/tags. Full names, globs, and
regular expressions are supported. If using a regular expression, the
expression must match the entire minion ID.
If used, branches/tags/SHAs which match one of the specified expressions will
*not* be exposed as fileserver environments.
If used in conjunction with :conf_master:`gitfs_env_whitelist`, then the subset

.. code-block:: yaml
gitfs_env_blacklist:
- base
- v1.*
- 'mybranch\d+'
hg: Mercurial Remote File Server Backend
----------------------------------------
.. conf_master:: hgfs_remotes
``hgfs_remotes``
****************
.. versionadded:: 0.17.0
Default: ``[]``
When using the ``hg`` fileserver backend at least one mercurial remote needs to
be defined. The user running the salt master will need read access to the repo.
The repos will be searched in order to find the file requested by a client and
the first repo to have the file will return it. Branches and/or bookmarks are
translated into salt environments, as defined by the
:conf_master:`hgfs_branch_method` parameter.
.. code-block:: yaml
hgfs_remotes:
- https://username@bitbucket.org/username/reponame
.. note::
As of 2014.7.0, it is possible to have per-repo versions of the
:conf_master:`hgfs_root`, :conf_master:`hgfs_mountpoint`,
:conf_master:`hgfs_base`, and :conf_master:`hgfs_branch_method` parameters.
For example:
.. code-block:: yaml
hgfs_remotes:
- https://username@bitbucket.org/username/repo1
- base: saltstates
- https://username@bitbucket.org/username/repo2:
- root: salt
- mountpoint: salt://foo/bar/baz
- https://username@bitbucket.org/username/repo3:
- root: salt/states
- branch_method: mixed
.. conf_master:: hgfs_branch_method
``hgfs_branch_method``
**********************
.. versionadded:: 0.17.0
Default: ``branches``
Defines the objects that will be used as fileserver environments.
* ``branches`` - Only branches and tags will be used
* ``bookmarks`` - Only bookmarks and tags will be used
* ``mixed`` - Branches, bookmarks, and tags will be used
.. code-block:: yaml
hgfs_branch_method: mixed
.. note::
Starting in version 2014.1.0, the value of the :conf_master:`hgfs_base`
parameter defines which branch is used as the ``base`` environment,
allowing for a ``base`` environment to be used with an
:conf_master:`hgfs_branch_method` of ``bookmarks``.
Prior to this release, the ``default`` branch will be used as the ``base``
environment.

``svnfs_remotes``
*****************
.. versionadded:: 0.17.0
Default: ``[]``
When using the ``svn`` fileserver backend at least one subversion remote needs
to be defined. The user running the salt master will need read access to the
repo.
The repos will be searched in order to find the file requested by a client and
the first repo to have the file will return it. The trunk, branches, and tags
become environments, with the trunk being the ``base`` environment.
.. code-block:: yaml
svnfs_remotes:
- svn://foo.com/svn/myproject

Pillar Configuration
====================
.. conf_master:: pillar_roots
``pillar_roots``
----------------
Default:
.. code-block:: yaml
base:
- /srv/pillar
Set the environments and directories used to hold pillar sls data. This
configuration is the same as :conf_master:`file_roots`:
.. code-block:: yaml
pillar_roots:
base:
- /srv/pillar
dev:
- /srv/pillar/dev
prod:
- /srv/pillar/prod
.. conf_master:: ext_pillar
``ext_pillar``
--------------
The ext_pillar option allows for any number of external pillar interfaces to be
called when populating pillar data. The configuration is based on ext_pillar
functions. The available ext_pillar functions can be found herein:
:blob:`salt/pillar`
By default, the ext_pillar interface is not configured to run.
Default: ``None``
.. code-block:: yaml
ext_pillar:
- hiera: /etc/hiera.yaml
- cmd_yaml: cat /etc/salt/yaml
- reclass:
inventory_base_uri: /etc/reclass
There are additional details at :ref:`salt-pillars`
.. conf_master:: pillar_source_merging_strategy
``pillar_source_merging_strategy``
----------------------------------
Default: ``smart``
The pillar_source_merging_strategy option allows to configure merging strategy
between different sources. It accepts 3 values:
* recurse:
it will merge recursively mapping of data. For example, theses 2 sources:
.. code-block:: yaml
foo: 42
bar:
element1: True
.. code-block:: yaml
bar:
element2: True
baz: quux
will be merged as:
.. code-block:: yaml
foo: 42
bar:
element1: True
element2: True
baz: quux
* aggregate:
instructs aggregation of elements between sources that use the #!yamlex rendered.
For example, these two documents:
.. code-block:: yaml
#!yamlex
foo: 42
bar: !aggregate {
element1: True
}
baz: !aggregate quux
.. code-block:: yaml
#!yamlex
bar: !aggregate {
element2: True
}
baz: !aggregate quux2
will be merged as:
.. code-block:: yaml
foo: 42
bar:
element1: True
element2: True
baz:
- quux
- quux2
* smart (default):
it guesses the best strategy, based on the "renderer" setting.
Syndic Server Settings
======================
A Salt syndic is a Salt master used to pass commands from a higher Salt master to
minions below the syndic. Using the syndic is simple. If this is a master that
will have syndic servers(s) below it, set the "order_masters" setting to True. If this
is a master that will be running a syndic daemon for passthrough the
"syndic_master" setting needs to be set to the location of the master server
Do not not forget that in other word it means that it shares with the local minion it's ID and PKI_DIR.
.. conf_master:: order_masters
``order_masters``
-----------------
Default: ``False``
Extra data needs to be sent with publications if the master is controlling a
lower level master via a syndic minion. If this is the case the order_masters
value must be set to True
.. code-block:: yaml
order_masters: False
.. conf_master:: syndic_master
``syndic_master``
-----------------
Default: ``None``
If this master will be running a salt-syndic to connect to a higher level
master, specify the higher level master with this configuration value
.. code-block:: yaml
syndic_master: masterofmasters
.. conf_master:: syndic_master_port
``syndic_master_port``
-----------------------
Default: ``4506``
If this master will be running a salt-syndic to connect to a higher level
master, specify the higher level master port with this configuration value
.. code-block:: yaml
syndic_master_port: 4506
.. conf_master:: syndic_log_file
.. conf_master:: syndic_master_log_file
``syndic_pidfile``
------------------
Default: ``salt-syndic.pid``
If this master will be running a salt-syndic to connect to a higher level
master, specify the pidfile of the syndic daemon.
.. code-block:: yaml
syndic_pidfile: syndic.pid
``syndic_log_file``
-------------------
Default: ``syndic.log``
If this master will be running a salt-syndic to connect to a higher level
master, specify the log_file of the syndic daemon.
.. code-block:: yaml
syndic_log_file: salt-syndic.log
Peer Publish Settings
=====================
Salt minions can send commands to other minions, but only if the minion is
allowed to. By default "Peer Publication" is disabled, and when enabled it
is enabled for specific minions and specific commands. This allows secure
compartmentalization of commands based on individual minions.
.. conf_master:: peer
``peer``
--------
Default: ``{}``
The configuration uses regular expressions to match minions and then a list
of regular expressions to match functions. The following will allow the
minion authenticated as foo.example.com to execute functions from the test
and pkg modules
.. code-block:: yaml
peer:
foo.example.com:
- test.*
- pkg.*
This will allow all minions to execute all commands:
.. code-block:: yaml
peer:
.*:
- .*
This is not recommended, since it would allow anyone who gets root on any
single minion to instantly have root on all of the minions!
By adding an additional layer you can limit the target hosts in addition to the
accessible commands:
.. code-block:: yaml
peer:
foo.example.com:
'db*':
- test.*
- pkg.*
.. conf_master:: peer_run
``peer_run``
------------
Default: ``{}``
The peer_run option is used to open up runners on the master to access from the
minions. The peer_run configuration matches the format of the peer
configuration.
The following example would allow foo.example.com to execute the manage.up
runner:
.. code-block:: yaml
peer_run:
foo.example.com:
- manage.up
.. _master-logging-settings:

-----------
Default: ``not defined``
The master can include configuration from other files. To enable this,
pass a list of paths to this option. The paths can be either relative or
absolute; if relative, they are considered to be relative to the directory
the main minion configuration file lives in. Paths can make use of
shell-style globbing. If no files are matched by a path passed to this
option then the master will log a warning message.
.. code-block:: yaml
# Include files from a master.d directory in the same
# directory as the master config file
include: master.d/*
