    # This configuration file is used to manage the behavior of the Salt Master.
    # Values that are commented out but have an empty line after the comment are
    # defaults that do not need to be set in the config. If there is no blank line
    # after the comment then the value is presented as an example and is not the
    # default.

    # Per default, the master will automatically include all config files

    # appear to initially respond after a key is rotated.
    #
    # Note that ping_on_rotate may cause high load on the master immediately after
    # the key rotation event as minions reconnect. Consider this carefully if this

    #####      File Server settings      #####
    ##########################################
    # 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:
    # file_roots:
    #   base:
    #     - /srv/salt/
    #   dev:
    #     - /srv/salt/dev/services
    #     - /srv/salt/dev/states
    #   prod:
    #     - /srv/salt/prod/services
    #     - /srv/salt/prod/states
    #
    #file_roots:
    #  base:
    #    - /srv/salt
    #

    # The master_roots setting configures a master-only copy of the file_roots dictionary,
    # used by the state compiler.
    #master_roots:
    #  base:
    #    - /srv/salt-master

    # When using multiple environments, each with their own top file, the
    # default behaviour is an unordered merge. To prevent top files from
    # being merged together and instead to only use the top file from the
    # requested environment, set this value to 'same'.
    #top_file_merging_strategy: merge

    # To specify the order in which environments are merged, set the ordering
    # in the env_order option. Given a conflict, the last matching value will
    # win.
    #env_order: ['base', 'dev', 'prod']

    # If top_file_merging_strategy is set to 'same' and an environment does not
    # contain a top file, the top file in the environment specified by default_top
    # will be used instead.
    #default_top: base

    # The hash_type is the hash to use when discovering the hash of a file on
    # the master server. The default is sha256, but md5, sha1, sha224, sha384 and
    # sha512 are also supported.
    #
    # WARNING: While md5 and sha1 are also supported, do not use them due to the
    # high chance of possible collisions and thus security breach.
    #
    # Prior to changing this value, the master should be stopped and all Salt
    # caches should be cleared.
    #hash_type: sha256

    # The buffer size in the file server can be adjusted here:
    #file_buffer_size: 1048576

    # 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($|/)'. By default nothing is ignored.
    #file_ignore_regex:
    #  - '/\.svn($|/)'
    #  - '/\.git($|/)'

    # 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.

    #  - '*.pyc'
    #  - '*/somefolder/*.bak'
    #  - '*.swp'

    # File Server Backend
    #
    # 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 uses the "file_roots" option.
    #fileserver_backend:
    #  - roots
    #
    # To use multiple backends list them in the order they are searched:
    #fileserver_backend:

    #  - roots
    #
    # Uncomment the line below if you do not want the file_server to follow
    # symlinks when walking the filesystem tree. This is set to True
    # by default. Currently this only applies to the default roots
    # fileserver_backend.
    #fileserver_followsymlinks: False
    #
    # Uncomment the line below if you do not want symlinks to be
    # treated as the files they are pointing to. By default this is set to
    # False. By uncommenting the line below, any detected symlink while listing
    # files on the Master will not be returned to the Minion.
    #fileserver_ignoresymlinks: True
    #
    # The fileserver can fire events off every time the fileserver is updated,

    # and the first repo to have the file will return it.
    # When using the git backend branches and tags are translated into salt

    #####      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.

    # 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.
    #peer:
    #  foo.example.com:
    #    - test.*
    #    - pkg.*
    #
    # This will allow all minions to execute all commands:
    #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!

    # Minions can also be allowed to execute runners from the salt master.
    # Since executing a runner from the minion could be considered a security risk,
    # it needs to be enabled. This setting functions just like the peer setting
    # except that it opens up runners instead of module functions.
    #
    # All peer runner support is turned off by default and must be enabled before
    # using. This will enable all peer runners for all minions:
    #peer_run:
    #  .*:
    #    - .*
    #
    # To enable just the manage.up runner for the minion foo.example.com:

    # In 'failover' mode, it is the number of attempts for each set of masters.
    # In this mode, it will cycle through the list of masters for each attempt.
    #
    # This is different than 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
    # the masters in a given try, so it is appropriate if you expect
    # occasional downtime from the master(s).

    # If you don't have any problems with syn-floods, don't bother with the
    # three recon_* settings described below, just leave the defaults!
    #
    # The ZeroMQ pull-socket that binds to the masters publishing interface tries
    # to reconnect immediately, if the socket is disconnected (for example if
    # the master processes are restarted). In large setups this will have all
    # minions reconnect immediately which might flood the master (the ZeroMQ-default
    # is usually a 100ms delay). To prevent this, these three recon_* settings
    # can be used.
    # recon_default: the interval in milliseconds that the socket should wait before
    #                trying to reconnect to the master (1000ms = 1 second)
    #
    # recon_max: 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 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
    #
    # recon_randomize: 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 your
    #                  setup is quite large (several thousand minions), they will still
    #                  flood the master. The desired behavior is to have timeframe within
    #                  all minions try to reconnect.
    #
    # Example on how to use these settings. The goal: have all minions reconnect within a

    # Each minion will have a randomized reconnect value between 'recon_default'
    # and 'recon_default + recon_max', which in this example means between 1000ms
    # 60000ms (or between 1 and 60 seconds). The generated random-value will be
    # doubled after each attempt to reconnect. Lets say the generated random
    # value is 11 seconds (or 11000ms).

    ##### Primary configuration settings #####
    ##########################################
    # This configuration file is used to manage the behavior of all Salt Proxy
    # Minions on this host.
    # With the exception of the location of the Salt Master Server, values that are
    # commented out but have an empty line after the comment are defaults that need
    # not be set in the config. If there is no blank line after the comment, the
    # value is presented as an example and is not the default.

    # Per default the proxy minion will automatically include all config files
    # from proxy.d/*.conf (proxy.d is a directory in the same directory
    # as the main minion config file).
    #default_include: proxy.d/*.conf

    # Backwards compatibility option for proxymodules created before 2015.8.2
    # This setting will default to 'False' in the 2016.3.0 release
    # Setting this to True adds proxymodules to the __opts__ dictionary.
    # This breaks several Salt features (basically anything that serializes
    # __opts__ over the wire) but retains backwards compatibility.
    #add_proxymodule_to_opts: True

    # Set the location of the salt master server. If the master server cannot be
    # resolved, then the minion will fail to start.
    #master: salt

    # If a proxymodule has a function called 'grains', then call it during
    # regular grains loading and merge the results with the proxy's grains
    # dictionary.  Otherwise it is assumed that the module calls the grains
    # function in a custom way and returns the data elsewhere
    #
    # Default to False for 2016.3 and 2016.11. Switch to True for 2017.7.0.
    # proxy_merge_grains_in_module: True

    # If a proxymodule has a function called 'alive' returning a boolean
    # flag reflecting the state of the connection with the remove device,
    # when this option is set as True, a scheduled job on the proxy will
    # try restarting the connection. The polling frequency depends on the
    # next option, 'proxy_keep_alive_interval'. Added in 2017.7.0.
    # proxy_keep_alive: True

    # The polling interval (in minutes) to check if the underlying connection
    # with the remote device is still alive. This option requires
    # 'proxy_keep_alive' to be configured as True and the proxymodule to
    # implement the 'alive' function. Added in 2017.7.0.
    # proxy_keep_alive_interval: 1

    # By default, any proxy opens the connection with the remote device when
    # initialized. Some proxymodules allow through this option to open/close
    # the session per command. This requires the proxymodule to have this
    # capability. Please consult the documentation to see if the proxy type
    # used can be that flexible. Added in 2017.7.0.
    # proxy_always_alive: True

    # If multiple masters are specified in the 'master' setting, the default behavior

    # When waiting for a master to accept the minion's public key, salt will
    # continuously attempt to reconnect until successful. This is the time, in

    #acceptance_wait_time: 10

    # If this is nonzero, the time between reconnection attempts will increase by

    #acceptance_wait_time_max: 0

    # If the master rejects the minion's public key, retry instead of exiting.
    # Rejected keys will be handled the same as waiting on acceptance.
    #rejected_retry: False

    # When the master key changes, the minion will try to re-auth itself to receive

    #random_reauth_delay: 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 acceptance_wait_time seconds before trying again. Unless your master
    # is under unusually heavy load, this should be left at the default.
    #auth_timeout: 60

    # Number of consecutive SaltReqTimeoutError that are acceptable when trying to
    # authenticate.
    #auth_tries: 7

    # If authentication fails due to SaltReqTimeoutError during a ping_interval,
    # cause sub minion process to restart.
    #auth_safemode: False

    # Ping Master to ensure connection is alive (minutes).

    # To auto recover minions if master changes IP address (DDNS)
    #    auth_tries: 10
    #    auth_safemode: False
    #    ping_interval: 90
    #
    # Minions won't know master is missing until a ping fails. After the ping fail,
    # the minion will attempt authentication and likely fails out and cause a restart.
    # When the minion restarts it will resolve the masters IP and attempt to reconnect.

    # If you don't have any problems with syn-floods, don't bother with the
    # three recon_* settings described below, just leave the defaults!
    #
    # The ZeroMQ pull-socket that binds to the masters publishing interface tries
    # to reconnect immediately, if the socket is disconnected (for example if
    # the master processes are restarted). In large setups this will have all
    # minions reconnect immediately which might flood the master (the ZeroMQ-default
    # is usually a 100ms delay). To prevent this, these three recon_* settings
    # can be used.
    # recon_default: the interval in milliseconds that the socket should wait before
    #                trying to reconnect to the master (1000ms = 1 second)
    #
    # recon_max: 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 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
    #
    # recon_randomize: 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 your
    #                  setup is quite large (several thousand minions), they will still
    #                  flood the master. The desired behavior is to have timeframe within
    #                  all minions try to reconnect.
    #
    # Example on how to use these settings. The goal: have all minions reconnect within a
    # 60 second timeframe on a disconnect.
    # recon_default: 1000
    # recon_max: 59000
    # recon_randomize: True
    #
    # Each minion will have a randomized reconnect value between 'recon_default'
    # and 'recon_default + recon_max', which in this example means between 1000ms
    # 60000ms (or between 1 and 60 seconds). The generated random-value will be
    # doubled after each attempt to reconnect. Lets say the generated random
    # value is 11 seconds (or 11000ms).
    # reconnect 1: wait 11 seconds
    # reconnect 2: wait 22 seconds
    # reconnect 3: wait 33 seconds
    # reconnect 4: wait 44 seconds
    # reconnect 5: wait 55 seconds
    # reconnect 6: wait time is bigger than 60 seconds (recon_default + recon_max)
    # reconnect 7: wait 11 seconds
    # reconnect 8: wait 22 seconds
    # reconnect 9: wait 33 seconds
    # reconnect x: etc.
    #
    # In a setup with ~6000 thousand hosts these settings would average the reconnects
    # to about 100 per second and all hosts would be reconnected within 60 seconds.

    # The loop_interval sets how long in seconds the minion will wait between

    #loop_interval: 60

    # 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.

    # One of 'garbage', 'trace', 'debug', 'info', 'warning', 'error', 'critical'.
    #
    # The following log levels are considered INSECURE and may log sensitive data:
    # ['garbage', 'trace', 'debug']
    #
    # Default: 'warning'
    #log_level: warning

    # The level of messages to send to the log file.
    # One of 'garbage', 'trace', 'debug', info', 'warning', 'error', 'critical'.
    # If using 'log_granular_levels' this must be set to the highest desired level.
    # Default: 'warning'
    #log_level_logfile:

    # The date and time format used in log messages. Allowed date/time formatting
    # can be seen here: http://docs.python.org/library/time.html#time.strftime
    #log_datefmt: '%H:%M:%S'
    #log_datefmt_logfile: '%Y-%m-%d %H:%M:%S'

    # The format of the console logging messages. Allowed formatting options can
    # be seen here: http://docs.python.org/library/logging.html#logrecord-attributes
    #
    # 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.
    #
    #log_fmt_console: '%(colorlevel)s %(colormsg)s'
    #log_fmt_console: '[%(levelname)-8s] %(message)s'
    #
    #log_fmt_logfile: '%(asctime)s,%(msecs)03d [%(name)-17s][%(levelname)-8s] %(message)s'

    # This can be used to control logging levels more specificically.  This
    # example sets the main salt library at the 'warning' level, but sets
    # 'salt.modules' to log at the 'debug' level:
    #   log_granular_levels:
    #     'salt': 'warning'
    #     'salt.modules': 'debug'
    #
    #log_granular_levels: {}

    # 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:
    #
    # [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 on the 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.
    #
    #zmq_monitor: False

    ######      Module configuration      #####
    ###########################################
    # Salt allows for modules to be passed arbitrary configuration data, any data
    # passed here in valid yaml format will be passed on to the salt minion modules
    # for use. It is STRONGLY recommended that a naming convention be used in which
    # the module name is followed by a . and then the value. Also, all top level
    # data must be applied via the yaml dict construct, some examples:
    #
    # You can specify that all modules should run in test mode:
    #test: True
    #
    # A simple value for the test module:
    #test.foo: foo
    #
    # A list for the test module:
    #test.bar: [baz,quo]
    #
    # A dict for the test module:
    #test.baz: {spam: sausage, cheese: bread}
    #

    # the OS. If connections between the minion and the master pass through
    # a state tracking device such as a firewall or VPN gateway, there is
    # the risk that it could tear down the connection the master and minion
    # without informing either party that their connection has been taken away.
    # Enabling TCP Keepalives prevents this from happening.

    # How long before the first keepalive should be sent in seconds. Default 300
    # to send the first keepalive after 5 minutes, OS default (-1) is typically 7200 seconds

    #tcp_keepalive_idle: 300

    # How many lost probes are needed to consider the connection lost. Default -1
    # to use OS defaults, typically 9 on Linux, see /proc/sys/net/ipv4/tcp_keepalive_probes.
