Salt Release Notes - Codename Sodium

Salt mine updates

Syntax update

The syntax for defining salt functions in config or pillar files has changed to also support the syntax used in module.run <salt.states.module.run>. The old syntax for the mine_function - as a dict, or as a list with dicts that contain more than exactly one key - is still supported but discouraged in favor of the more uniform syntax of module.run.

Salt-SSH updates

A new Salt-SSH roster option ssh_pre_flight has been added. This enables you to run a script before Salt-SSH tries to run any commands. You can set this option in the roster for a specific minion or use the roster_defaults to set it for all minions.

Example for setting ssh_pre_flight for specific host in roster file

minion1:
  host: localhost
  user: root
  passwd: P@ssword
  ssh_pre_flight: /srv/salt/pre_flight.sh

Example for setting ssh_pre_flight using roster_defaults, so all minions run this script.

roster_defaults:
  ssh_pre_flight: /srv/salt/pre_flight.sh

The ssh_pre_flight script will only run if the thin dir is not currently on the minion. If you want to force the script to run you have the following options: - Wipe the thin dir on the targeted minion using the -w arg. - Set ssh_run_pre_flight to True in the config. - Run salt-ssh with the --pre-flight arg.
