The Commands

docker stack deploy is the command for deploying and updating stacks of services defined in a stack file (usually called docker-stack.yml).

docker stack ls lists all stacks on the Swarm, including how many services they have.

docker stack ps gives detailed information about a deployed stack. It accepts the name of the stack as its main argument, lists which node each replica is running on, and shows desired state and current state.

docker stack rm deletes a stack from the Swarm. It does not ask for confirmation before deleting the stack.
