menew commented on issue #105: invoker-0 stuck in CrashLoopBackOff loop probably due to issues creating a kafka topic URL: https://github.com/apache/incubator-openwhisk-deploy-kube/issues/105#issuecomment-349925831 Hi, I've experienced almost same issue on controller deployment. Controller pods seem to be started, but suddenly shutdown with error message `ensureTopic for completed0 failed` after 120 seconds of silence (I removed `livenessProve` key to debug the pod). After investigating, I found that this failure is caused by misconfiguration of Kafka pod. I simply deployed Kafka by `kafka.yml` from this repository, then it looked booted up correctly and port 9092 was reachable from other pods on TCP layer. But, without kube-dns, it seems that consumers/producers cannot reach the Kafka pod on application layer because name `kafka.openwhisk` set in `KAFKA_ADVERTISED_HOSTNAME` is not resolvable. So, I replaced value `kafka.openwhisk` by `$(KAFKA_SERVICE_HOST)` in deployment YAML file, then controller pods started correctly. They responded to `curl` on `/ping` and some `wsk` commands. Of course my issue can be different from this one, but sanity check on your Kafka deployment might help (for example, I followed "Usage Quick Start" steps in https://github.com/ches/docker-kafka README with `docker run -it --net host --rm ches/kafka bash` container).
