: Docker Service update registry \ --constraint-add ' Node.labels.security==high ' 2. Volume Creation Management With service constraints, we can guarantee that our registry service has been on the NODE01 node. But there is another problem, if we delete the registry service. The image of the container we uploaded is also deleted. How do I guarantee that a mirror can be preserved even if the registry service is deleted? Here we can use
