Example code:

@when('actions.stop')
def stop_vnf():
    err = ''
    try:
        """
        Run the command(s) necessary to perform a safe stop of your VNF
        This could be a single command that encapsulates your stop process...
        Or a series of commands for each step, such as:
         - stop accepting live traffic
         - perform cool-down operations
         - stop your vnf
        """
        result, err = charms.sshproxy._run("/srv/myvnf/stop.sh")
    except:
        action_fail('Stop failed:' + err)
    else:
        action_set({'outout': result})
    finally:
        clear_flag('actions.stop')
