This seems like we're just asking the docker module to guarantee that the service is running. Not to restart the service. I think we need to be explicit here that we aren't just saying "ensure service is running" but are actually saying "restart the service, picking up a new version if that's deployed". -Toshio -- You received this message because you are subscribed to the Google Groups "Ansible Project" group.
