public class GroupPlacementStrategy
extends AbstractDockerPlacementStrategy
implements org.apache.brooklyn.util.core.mutex.WithMutexes

A strategy that requires entities with the same parent to use the same host and entities with a different parent but in the same app use different hosts. Can be configured to require exclusive use of the host with the exclusive (docker.constraint.exclusive) option set to true; normally false.

Since:

1.1.0
