Lab7 - Cleaning Up

Execute the docker service rm sleep-app command on manager1 to remove the service called sleep-app.

$ docker service rm sleep-app
sleep-app
[manager1] (local) root@192.168.0.9 ~/dockerlabs/intermediate/swarm
$ docker service ls
ID                  NAME                MODE                REPLICAS            IMAGE     PORTS

Execute the docker ps command on node1 to get a list of running containers.

docker ps
CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS               NAMES
044bea1c2277        ubuntu              "sleep infinity"    17 minutes ago      17 minutes ag                           distracted_mayer

You can use the docker kill command on node1 to kill the sleep container we started at the beginning.

docker kill yourcontainerid

Finally, let’s remove node1, node2, and node3 from the Swarm. We can use the docker swarm leave --force command to do that.

Lets run docker swarm leave --force on all the nodes to leave swarm cluster.

docker swarm leave --force

Congratulations! You’ve completed this lab. You now know how to build a swarm, deploy applications as collections of services, and scale individual services up and down.
