Mar 26, 2020  Next, we will accept the salt-key for the minion on the salt master server. Root@host:# salt-key -A The following keys are going to be accepted: Unaccepted Keys: ubuntu-minion01 Proceed? n/Y y Key for minion ubuntu-minion01 accepted. Sharing knowledge helps me generate new ideas and stay motivated. View all posts by Ellen. On master, delete current key: sudo salt-key -d minionname. On minion, restart the service: sudo systemctl restart salt-minion (or sudo service salt-minion restart on an older, non-systemd OS) Back to master, accept the new key: sudo salt-key -a minionname. Salt authenticates minions using public-key encryption and authentication. For a minion to start accepting commands from the master, the minion keys need to be accepted by the master. The salt-key command is used to manage all of the keys on the master. Preseed Minion with Accepted Key¶ In some situations, it is not convenient to wait for a minion to start before accepting its key on the master. For instance, you may want the minion to bootstrap itself as soon as it comes online. You may also want to let your developers provision new development machines on the fly.

SaltStack is a powerful configuration management tool. The following is a quick-reference guide for Salt’s command line interface (CLI).

salt

Used to issue commands to minions in parallel. salt allows you to both control and query minions.

OptionDescriptionExample
--versionGet the current version of Salt.salt --version
-h, --helpDisplay Salt commands and help text.salt -h
-c, --config-dirChange the Salt configuration directory. The default is /etc/salt.salt -c /home/salt/conf test.ping
-s, --staticOnly return data after all minions have returned.salt --static
--asyncInstead of waiting for a job on a minion or minions, print the job ID and the job completion.salt '*' pkg.install apache2 --async
--subsetExecute commands on a random subset of minions.salt '*' telegram.post_message message='Hello random 3!' --subset 3
-v, --verbosePrint extra data, such as the job ID.salt 'minion1' user.add steve --verbose
--hide-timeoutOnly print minions that can be reached.salt '*' test.ping --hide-timeout
-b, --batch-sizeExecute on a batch or percentage of minions.salt '*' test.ping --batch-size 25%
-a, --authUse an external authentication medium. You will be prompted for credentials. Options are auto, keystone, ldap, and pam. Can be used with -T.salt -a pam '*' status.meminfo
-T, --make-tokenUsed with -a. Creates an authentication token in the active user’s home directory that has a default 12 hour expiration time. Token expiration time is set in the Salt master config file.salt -T -a pam '*' status.cpuinfo
--returnUsed to select an alternative returner. 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.salt '*' status.all_status --return mongo
