##### Primary configuration settings ##### ########################################## # This configuration file is used to manage the behavior of the Salt Minion. # 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 minion will automatically include all config files # from minion.d/*.conf (minion.d is a directory in the same directory # as the main minion config file). #default_include: minion.d/*.conf # 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 multiple masters are specified in the 'master' setting, 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. 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 will be logged. #random_master: False # Minions can connect to multiple masters simultaneously (all masters # are "hot"), or can be configured to failover if a master becomes # unavailable. Multiple hot masters are configured by setting this # value to "str". Failover masters can be requested by setting # to "failover". MAKE SURE TO SET master_alive_interval if you are # using failover. # master_type: str # Poll interval in seconds for checking if the master is still there. Only # respected if master_type above is "failover". # master_alive_interval: 30 # Set whether the minion should connect to the master via IPv6: #ipv6: False # 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. # retry_dns: 30 # Set the port used by the master reply and authentication server. #master_port: 4506 # The user to run salt. #user: root # Setting sudo_user will cause salt to run all execution modules under an sudo # to the user given in sudo_user. The user under which the salt minion process # itself runs will still be that provided in the user config above, but all # execution modules run by the minion will be rerouted through sudo. #sudo_user: saltdev # Specify the location of the daemon process ID file. #pidfile: /var/run/salt-minion.pid # The root directory prepended to these options: pki_dir, cachedir, log_file, # sock_dir, pidfile. #root_dir: / # The directory to store the pki information in #pki_dir: /etc/salt/pki/minion # Explicitly declare the id for this minion to use, if left commented the id # will be the hostname as returned by the python call: socket.getfqdn() # Since salt uses detached ids it is possible to run multiple minions on the # same machine but with different ids, this can be useful for salt compute # clusters. #id: # 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). #append_domain: # Custom static grains for this minion can be specified here and used in SLS # files just like all other grains. This example sets 4 custom grains, with # the 'roles' grain having two values that can be matched against. #grains: # roles: # - webserver # - memcache # deployment: datacenter4 # cabinet: 13 # cab_u: 14-15 # # Where cache data goes. # This data may contain sensitive data and should be protected accordingly. #cachedir: /var/cache/salt/minion # Verify and set permissions on configuration directories at startup. #verify_env: True # The minion can locally cache the return data from jobs sent to it, this # can be a good way to keep track of jobs the minion has executed # (on the minion side). By default this feature is disabled, to enable, set # cache_jobs to True. #cache_jobs: False # Set the directory used to hold unix sockets. #sock_dir: /var/run/salt/minion # Set the default outputter used by the salt-call command. The default is # "nested". #output: nested # # By default output is colored. To disable colored output, set the color value # to False. #color: True # Do not strip off the colored output from nested results and state outputs # (true by default). # strip_colors: False # Backup files that are replaced by file.managed and file.recurse under # 'cachedir'/file_backups relative to their original location and appended # with a timestamp. The only valid setting is "minion". Disabled by default. # # Alternatively this can be specified for each file in state files: # /etc/ssh/sshd_config: # file.managed: # - source: salt://ssh/sshd_config # - backup: minion # #backup_mode: minion # 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 # seconds, between those reconnection attempts. #acceptance_wait_time: 10 # If this is nonzero, the time between reconnection attempts will increase by # acceptance_wait_time seconds per iteration, up to this maximum. If this is # set to zero, the time between reconnection attempts will stay constant. #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 # 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. #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). #ping_interval: 0 # 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. # recon_default: 100 # recon_max: 5000 # recon_randomize: False # # # The loop_interval sets how long in seconds the minion will wait between # evaluating the scheduler and running cleanup tasks. This defaults to a # sane 60 seconds, but if the minion scheduler needs to be evaluated more # often lower this value #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. # # Note: This value is expressed in __minutes__! # # A value of 10 minutes is a reasonable default. # # If the value is set to zero, this check is disabled. #grains_refresh_every: 1 # Cache grains on the minion. Default is False. #grains_cache: False # Grains cache expiration, in seconds. If the cache file is older than this # number of seconds then the grains cache will be dumped and fully re-populated # with fresh data. Defaults to 5 minutes. Will have no effect if 'grains_cache' # is not enabled. # grains_cache_expiration: 300 # Windows platforms lack posix IPC and must rely on slower TCP based inter- # process communications. Set ipc_mode to 'tcp' on such systems #ipc_mode: ipc # Overwrite the default tcp ports used by the minion when in tcp mode #tcp_pub_port: 4510 #tcp_pull_port: 4511 # 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. #max_event_size: 1048576 # To detect failed master(s) and fire events on connect/disconnect, set # master_alive_interval to the number of seconds to poll the masters for # connection events. # #master_alive_interval: 30 # 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 (this file). 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. # # Include a config file from some other path: # include: /etc/salt/extra_config # # Include config from several files and directories: #include: # - /etc/salt/extra_config # - /etc/roles/webserver # # # ##### Minion module management ##### ########################################## # Disable specific modules. This allows the admin to limit the level of # access the master has to the minion. #disable_modules: [cmd,test] #disable_returners: [] # # Modules can be loaded from arbitrary paths. This enables the easy deployment # of third party modules. Modules for returners and minions can be loaded. # Specify a list of extra directories to search for minion modules and # returners. These paths must be fully qualified! #module_dirs: [] #returner_dirs: [] #states_dirs: [] #render_dirs: [] #utils_dirs: [] # # A module provider can be statically overwritten or extended for the minion # via the providers option, in this case the default module will be # overwritten by the specified module. In this example the pkg module will # be provided by the yumpkg5 module instead of the system default. #providers: # pkg: yumpkg5 # # Enable Cython modules searching and loading. (Default: False) #cython_enable: False # # Specify a max size (in bytes) for modules on import. This feature is currently # only supported on *nix operating systems and requires psutil. # modules_max_memory: -1 ##### State Management Settings ##### ########################################### # The state management system executes all of the state templates on the minion # to enable more granular control of system state management. The type of # template and serialization used for state management needs to be configured # on the minion, the default renderer is yaml_jinja. This is a yaml file # rendered from a jinja template, the available options are: # yaml_jinja # yaml_mako # yaml_wempy # json_jinja # json_mako # json_wempy # #renderer: yaml_jinja # # The failhard option tells the minions to stop immediately after the first # failure detected in the state execution. Defaults to False. #failhard: False # # Reload the modules prior to a highstate run. #autoload_dynamic_modules: 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. #clean_dynamic_modules: True # # 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. #environment: None # # If using the local file directory, then the state top file name needs to be # defined, by default this is top.sls. #state_top: top.sls # # Run states 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 #startup_states: '' # # List of states to run when the minion starts up if startup_states is 'sls': #sls_list: # - edit.vim # - hyper # # Top file to execute if startup_states is 'top': #top_file: '' # Automatically aggregate all states that have support for mod_aggregate by # setting to True. Or pass a list of state module names to automatically # aggregate just those types. # # state_aggregate: # - pkg # #state_aggregate: False ##### File Directory Settings ##### ########################################## # The Salt Minion can redirect all file server operations to a local directory, # this allows for the same state tree that is on the master to be used if # copied completely onto the minion. This is a literal copy of the settings on # the master but used to reference a local directory on the minion. # Set the file client. The client defaults to looking on the master server for # files, but can be directed to look at the local file directory setting # defined below by setting it to "local". Setting a local file_client runs the # minion in masterless mode. #file_client: remote # The file directory works on environments passed to the minion, 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 # 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, # enable the option below. This might be useful for installations where a file root # has a very large number of files and performance is negatively impacted. Default # is False. #fileserver_limit_traversal: False # The hash_type is the hash to use when discovering the hash of a file in # the local fileserver. The default is md5, but sha1, sha224, sha256, sha384 # and sha512 are also supported. # # Warning: Prior to changing this value, the minion should be stopped and all # Salt caches should be cleared. #hash_type: md5 # The Salt pillar is searched for locally if file_client is set to local. If # this is the case, and pillar data is defined, then the pillar_roots need to # also be configured on the minion: #pillar_roots: # base: # - /srv/pillar # # ###### Security settings ##### ########################################### # Enable "open mode", this mode still maintains encryption, but turns off # authentication, this is only intended for highly secure environments or for # the situation where your keys end up in a bad state. If you run in open mode # you do so at your own risk! #open_mode: 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. #permissive_pki_access: False # The state_verbose and state_output settings can be used to change the way # state system data is printed to the display. By default all data is printed. # The state_verbose setting can be set to True or False, when set to False # all data that has a result of True and no changes will be suppressed. #state_verbose: True # 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. #state_output: full # 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. #state_output_diff: False # The state_output_profile setting changes whether profile information # will be shown for each state run. #state_output_profile: True # 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. #master_finger: '' ###### Thread settings ##### ########################################### # Disable multiprocessing support, by default when a minion receives a # publication a new process is spawned and the command is executed therein. #multiprocessing: True ##### Logging settings ##### ########################################## # The location of the minion log file # The minion log can be sent to a regular file, local path name, or network # location. Remote logging works best when configured to use rsyslogd(8) (e.g.: # ``file:///dev/log``), with rsyslogd(8) configured for network logging. The URI # format is: ://:/ #log_file: /var/log/salt/minion #log_file: file:///dev/log #log_file: udp://loghost:10514 # #log_file: /var/log/salt/minion #key_logfile: /var/log/salt/key # The level of messages to send to the console. # 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.

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'.

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} # # ###### Update settings ###### ########################################### # Using the features in Esky, a salt minion can both run as a frozen app and # be updated on the fly. These options control how the update process # (saltutil.update()) behaves. # # The url for finding and downloading updates. Disabled by default. #update_url: False # # The list of services to restart after a successful update. Empty by default. #update_restart_services: [] ###### Keepalive settings ###### ############################################ # ZeroMQ now includes support for configuring SO_KEEPALIVE if supported by # 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. # Overall state of TCP Keepalives, enable (1 or True), disable (0 or False) # or leave to the OS defaults (-1), on Linux, typically disabled.
