• How do I kill salt in a task that is being performed?

Document Https://docs.saltstack.com/en/latest/ref/modules/all/salt.modules.saltutil.html#module-salt.modules.saltutil

Salt ' * ' saltutil.running # view running tasks, find Jid

Salt ' * ' Saltutil.kill_job Jid # Kill task According to Jid

Salt ' * ' Saltutil.clear_cache # Clear Minion Cache

Note:

1) The salt task being performed, the job ID will exist in the/var/cache/salt/minion/proc directory on the Minion side

2) The salt task being performed, based on the configuration of the master cache above, the job path/var/cache/salt/master/jobs directory

Salt Runners

Official Document Https://docs.saltstack.com/en/latest/ref/runners/index.html

Command: Salt-run

Example:

Salt-run jobs.list_jobs  # Lists the historical execution tasks currently saved in the job cache Salt-run Jobs.lookup_jid Jid  # View history Jid Execution Results

remark: when we execute at the beginning of the Salt command, all the command master is distributed to the Minion side, executed by the Minion side, and if a module exists in master and does not exist on the Minion side, execution failure occurs. To solve this problem, provide the Salt runners module, which is to execute all the commands on the master side.

Salt-run Manage.status # View the status of Minion

Salt-run Manage.downsalt-run Manage.up

Salt-run manage.versions # View version of Minion
