How can I remove shutdown Docker Service tasks after a rolling update?

I did

docker swarm update --task-history-limit 2

docker-machine stop manager1

docker-machine start manager1

and

PS C:\> docker service ps web | Select-String "manager1"

Thank you, Geige V

The containers for those services are removed after a rolling update; you are simply left with a log of those that were shutdown.

You can limit the number you see using

docker swarm update --task-history-limit 5
