Using conditional to execute a command in salt

0 votes

I am trying to run this command in a salt state:

mysql_install_db --user=mysql --basedir=/usr/ --ldata=/data/mysql/

But I want this to run only if the /data/mysql directory is empty i.e. there are no databases in it. Is there any conditional I can use here?

You can use unless inside your state file to verify the existence of path:

mysql_install_db:
  cmd.run: 
    - name: mysql_install_db --user=mysql --basedir=/usr/ --ldata=/data/mysql/
    - unless: file.path_exists_glob('/data/mysql/*')
