Before using the docker stack rm command to remove a stack, you will probably want to first use the docker stack ls command can be used to list the stacks. This command must be run from the swarm manager. Something like this should be returned.

~]# docker stack ls
NAME  SERVICES  ORCHESTRATOR
foo   3         Swarm
bar   1         Swarm

Let's say you want to remove the "foo" stack. If the removal is successful, something like this should be displayed.

Any container associated with the stack should also be removed.

~]# docker stack rm foo
Removing service foo
Removing network foo
