Directory structure
There are two essential locations for salt related files (excluding service files):
/etc/salt
/srv/salt
/etc/salt holds configuration files for the master and minion, as well as the keys for known minions.
/srv/salt has the state, pillar and reactor files.

Add new salt state
Salt states are the equivalent to a cookbook in Chef or a module in Puppet. To create a new one, do the following:
- Login to the salt master
mkdir /srv/salt/<name of state>- Add your logic to
/srv/salt/<name of state>/init.sls

Run state on all minions
salt '*' state.apply
Alternatively, you can specify one from the command line:
salt '*' state.apply <name of state>
Run state on single minion
salt '<minion name>' state.apply
Alternatively, you can specify one from the command line:
salt '<minion name>' state.apply <name of state>
Commands to run on minion
Test connection to master
salt-call -l debug test.ping
