问题
On the local host, I can remove an image using either docker image rm or docker rmi.
What if my current host is a manager node in a Docker swarm and I wish to cascade this operation throughout the swarm?
When I first created the Docker service, the image was pulled down on each node in the swarm. Removing the service did not remove the image and all nodes retain a copy of the image.
It feels natural that if there's a way to "push" an image out to all the nodes then there should be an equally natural way to remove them too without having to SSH into every single machine :'( Plus, this is a real problem. Sooner or later the nodes are bound to have no more disk space!

AFAIK there is no such option as of now. Each node is responsible of its own cleanup. There is a command docker system prune -f that you can use to clear container data.
But tagged images can be deleted using docker rmi only. See below issues
