Cleanup Sequence

1. Check current usage:

   check_resource_thresholds
   docker_state host="<host>"
   

2. Preview cleanup (dry-run):

   ssh_exec "docker system df" host="<host>"
   

3. Execute cleanup:

   ssh_exec "docker system prune -f" host="<host>"
   ssh_exec "docker image prune -a --filter 'until=168h' -f" host="<host>"
   

4. Verify results:

   check_resource_thresholds
