We are not the kind to leave useless services around, so we will remove our stack and stop our Swarm cluster as we prepare for the next chapter:

$ docker stack rm swarm_test
Removing service swarm_test_application-server
Removing service swarm_test_web-server
Removing service swarm_test_local-database
Removing network swarm_test_service_network

$ docker swarm leave --force
Node left the swarm.

We won't need to clean up the network or running containers as they will automatically get removed by Docker once our stack is gone. With this part done, we can now move on to the next chapter about volumes with a clean slate.
