set config on salt minion from salt master

I need to set the saltstack configuration of a salt minion from a salt master. The salt.modules.config only appears to support getting configuration from the minion.

https://docs.saltstack.com/en/latest/ref/modules/all/salt.modules.config.html

salt '*' config.get file_roots

returns the file_roots from each minion, but surprisingly you can't execute

salt '*' config.set file_roots <custom configuration>

The only solution I can think of is to edit the /etc/salt/minion file using the salt.states.file module (https://docs.saltstack.com/en/latest/ref/states/all/salt.states.file.html) and restart the salt-minion service. However, I have a hunch there is a better solution.

You should manage the files in /etc/salt/minion.d/ using Salt states.

An example (there are other ways to manage the restart):

/etc/salt/minion.d/default_env.conf:
  file.serialize:
    - dataset:
        saltenv: base
        pillarenv_from_saltenv: true
    - formatter: yaml

/etc/salt/minion.d/logging.conf:
  file.serialize:
    - dataset:
        log_fmt_console: '[%(levelname)s] %(message)s %(jid)s'
        log_fmt_logfile: '%(asctime)s,%(msecs)03d [%(name)-17s][%(levelname)-8s] %(message)s %(jid)s'
        logstash_udp_handler:
          host: logstash
          port: 10514
          version: 1
          msg_type: saltstack
    - formatter: yaml

salt-minion:
  service.running:
    - enable: true
    - watch:
      - file: /etc/salt/minion.d/*

Stop state.apply to allow minion restart:
  test.fail_without_changes:
    - order: 1
    - failhard: true
    - onchanges:
      - service: salt-minion

Yes, Salt can Salt itself!

We use the salt-formula to salt minions. The master might also be salted using this formula.
