A few “one off” commands using salt stack listed by their potential use.

Maintenance should be done through the state system. But sometimes we still need “one off” commands on servers themselves and it would be creating cruft to have them in the state scripts.

Using salt from the salt master

Since everything should be managed through salt, but we are in a situation where we might not want to change the states, we can do the following commands.

Remove a file

 salt \* file.remove /etc/monit/conf.d/exim4.conf

Remove a user

 salt \* user.delete foobar remove=True force=True

Replace a line in a config file

 salt app\* file.replace /etc/php5/apache2/php.ini pattern='expose_php = On' repl='expose_php = Off'

Reload a service

 salt app\* service.reload apache2
