fabric:container-delete command does not display an appropriate message

1: create an ensemble server environment(4 instances) using ssh containers 2: login to one of a remote fabric server's console 3: remove root container from ensemble members fabric:ensemble-remove root 4: delete root container from fabric fabric:container-delete --force root Actual Result Error message is displayed on the console Error executing command: Container's lifecycle not managed by Fabric8 (the container was not created by Fabric8). It looks like the command could not execute successfully, "container-list" command will now list root container's info anymore. Expected Behavior The output message of "fabric:container-delete" shows what was operated successfully and what was not.
