sven-lange-last commented on issue #2662: Add judge condition for invoker deployment URL: https://github.com/apache/incubator-openwhisk/pull/2662#issuecomment-344951611 - Well, this PR just wants to introduce a guard that supports re-running the invoker playbook without affecting a deployed invoker. - At the same time, @markusthoemmes is asking @ningyougang for a re-create behaviour. - I think @ningyougang is right with his assessment that a simple re-creation would drop / impact running user invocations as well as dropping some invocations that have already been received from Kafka. - A reasonable invoker re-create playbook has to include an invoker drain and re-enablement. - @ningyougang - is my understanding correct that you want to improve robustness of the invoker playbook? - @rabbah - I just have a way to run Ansible playbooks such that an already broken invoker can be refreshed without affecting the other invokers: `ansible-playbook -i environments/... -e docker_image_tag=$TAG --limit=$INVOKER_HOST openwhisk.yml -e mode=clean` and `ansible-playbook -i environments/... -e docker_image_tag=$TAG --limit=$INVOKER_HOST openwhisk.yml`.
