salt - Man Page
Examples (TL;DR)
- List connected minions:
salt '*' test.ping - Execute a highstate on all connected minions:
salt '*' state.highstate - Upgrade packages using the OS package manager (apt, yum, brew) on a subset of minions:
salt '*.example.com' pkg.upgrade - Execute an arbitrary command on a particular minion:
salt 'minion_id' cmd.run "ls "
Synopsis
Description
Salt allows for commands to be executed across a swath of remote systems in parallel. This means that remote systems can be both controlled and queried with ease.
Options
- --version
Print the version of Salt that is running.
- --versions-report
Show program's dependencies and version number, and then exit
- -h, --help
Show the help message and exit
- -c CONFIG_DIR, --config-dir=CONFIG_dir
The location of the Salt configuration directory. This directory contains the configuration files for Salt master and minions. The default location on most systems is /etc/salt.
- -t TIMEOUT, --timeout=TIMEOUT
The timeout in seconds to wait for replies from the Salt minions. The timeout number specifies how long the command line client will wait to query the minions and check on running jobs. Default: 5
- -s, --static
By default as of version 0.9.8 the salt command returns data to the console as it is received from minions, but previous releases would return data only after all data was received. Use the static option to only return the data with a hard timeout and after all minions have returned. Without the static option, you will get a separate JSON string per minion which makes JSON output invalid as a whole.
- --async
Instead of waiting for the job to run on minions only print the job id of the started execution and complete.
- --subset=SUBSET
Execute the routine on a random subset of the targeted minions. The minions will be verified that they have the named function before executing. The SUBSET argument is the count of the minions to target.
- -v VERBOSE, --verbose
Turn on verbosity for the salt call, this will cause the salt command to print out extra data like the job id.
- --hide-timeout
Instead of showing the return data for all minions. This option prints only the online minions which could be reached.
- -b BATCH, --batch-size=BATCH
Instead of executing on all targeted minions at once, execute on a progressive set of minions. This option takes an argument in the form of an explicit number of minions to execute at once, or a percentage of minions to execute on.
- --batch-wait=BATCH_WAIT
Wait the specified time in seconds after each job is done before freeing the slot in the batch of the next one.
- --batch-safe-limit=BATCH_SAFE_LIMIT
Execute the salt job in batch mode if the job would have executed on at least this many minions.
- --batch-safe-size=BATCH_SAFE_SIZE
Batch size to use for batch jobs created by --batch-safe-limit.
- -a EAUTH, --auth=EAUTH
Pass in an external authentication medium to validate against. The credentials will be prompted for. The options are auto, keystone, ldap, and pam. Can be used with the -T option.
- -T, --make-token
Used in conjunction with the -a option. This creates a token that allows for the authenticated user to send commands without needing to re-authenticate.
- --return=RETURNER
Choose an alternative returner to call on the minion, if an alternative returner is used then the return will not come back to the command line but will be sent to the specified return system. The options are carbon, cassandra, couchbase, couchdb, elasticsearch, etcd, hipchat, local, local_cache, memcache, mongo, mysql, odbc, postgres, redis, sentry, slack, sms, smtp, sqlite3, syslog, and xmpp.
- -d, --doc, --documentation
Return the documentation for the module functions available on the minions
- --args-separator=ARGS_SEPARATOR
Set the special argument used as a delimiter between command arguments of compound commands. This is useful when one wants to pass commas as arguments to some of the commands in a compound command.
Logging Options
Logging options which override any settings defined on the configuration files.
- -l LOG_LEVEL, --log-level=LOG_LEVEL
Console logging log level. One of all, garbage, trace, debug, info, warning, error, quiet. Default: warning.
- --log-file=LOG_FILE
Log file path. Default: /var/log/salt/master.
- --log-file-level=LOG_LEVEL_LOGFILE
Logfile logging log level. One of all, garbage, trace, debug, info, warning, error, quiet. Default: warning.
Target Selection
The default matching that Salt utilizes is shell-style globbing around the minion id. See https://docs.python.org/3/library/fnmatch.html#module-fnmatch.
- -E, --pcre
The target expression will be interpreted as a PCRE regular expression rather than a shell glob.
- -L, --list
The target expression will be interpreted as a comma-delimited list; example: server1.foo.bar,server2.foo.bar,example7.quo.qux
- -G, --grain
The target expression matches values returned by the Salt grains system on the minions. The target expression is in the format of '<grain value>:<glob expression>'; example: 'os:Arch*'
This was changed in version 0.9.8 to accept glob expressions instead of regular expression. To use regular expression matching with grains, use the --grain-pcre option.
- --grain-pcre
The target expression matches values returned by the Salt grains system on the minions. The target expression is in the format of '<grain value>:< regular expression>'; example: 'os:Arch.*'
- -N, --nodegroup
Use a predefined compound target defined in the Salt master configuration file.
- -R, --range
Instead of using shell globs to evaluate the target, use a range expression to identify targets. Range expressions look like %cluster.
Using the Range option requires that a range server is set up and the location of the range server is referenced in the master configuration file.
- -C, --compound
Utilize many target definitions to make the call very granular. This option takes a group of targets separated by and or or. The default matcher is a glob as usual. If something other than a glob is used, preface it with the letter denoting the type; example: 'webserv* and G@os:Debian or E@db*' Make sure that the compound target is encapsulated in quotes.
- -I, --pillar
Instead of using shell globs to evaluate the target, use a pillar value to identify targets. The syntax for the target is the pillar key followed by a glob expression: "role:production*"
- -S, --ipcidr
Match based on Subnet (CIDR notation) or IPv4 address.
Output Options
- --out
Pass in an alternative outputter to display the return of data. This outputter can be any of the available outputters:
highstate, json, key, overstatestage, pprint, raw, txt, yaml, and many others.
Some outputters are formatted only for data returned from specific functions. If an outputter is used that does not support the data passed into it, then Salt will fall back on the pprint outputter and display the return data using the Python pprint standard library module.
- --out-indent OUTPUT_INDENT, --output-indent OUTPUT_INDENT
Print the output indented by the provided value in spaces. Negative values disable indentation. Only applicable in outputters that support indentation.
- --out-file=OUTPUT_FILE, --output-file=OUTPUT_FILE
Write the output to the specified file.
- --out-file-append, --output-file-append
Append the output to the specified file.
- --no-color
Disable all colored output
- --force-color
Force colored output
NOTE:
When using colored output the color codes are as follows:
green denotes success, red denotes failure, blue denotes changes and success and yellow denotes a expected future change in configuration.
- --state-output=STATE_OUTPUT, --state_output=STATE_OUTPUT
Override the configured state_output value for minion output. One of 'full', 'terse', 'mixed', 'changes' or 'filter'. Default: 'none'.
- --state-verbose=STATE_VERBOSE, --state_verbose=STATE_VERBOSE
Override the configured state_verbose value for minion output. Set to True or False. Default: none.
- NOTE:
If using --out=json, you will probably want --static as well. Without the static option, you will get a separate JSON string per minion which makes JSON output invalid as a whole. This is due to using an iterative outputter. So if you want to feed it to a JSON parser, use --static as well.
