The remaining steps in the tutorial don’t use the helloworld
service, so now
you can delete the service from the swarm.
If you haven’t already, open a terminal and ssh into the machine where you
run your manager node. For example, the tutorial uses a machine named
manager1
.
Run docker service rm helloworld
to remove the helloworld
service.
$ docker service rm helloworld
helloworld
Run docker service inspect <SERVICE-ID>
to verify that the swarm manager
removed the service. The CLI returns a message that the service is not
found:
$ docker service inspect helloworld
[]
Error: no such service: helloworld
Even though the service no longer exists, the task containers take a few
seconds to clean up. You can use docker ps
to verify when they are gone.
$ docker ps

In the next step of the tutorial, you set up a new service and apply a rolling update.
