   Looks to me like you have most likely some kind of networking problem.  The kafka pod's init_container doesn't think zookeeper is ready.
   ````
   Init Containers:
     wait-for-zookeeper:
       Container ID:  docker://4b9db4e302ddf91200721d537b150c4b28b5942c4a4a71ea9adfe5eba2162881
       Image:         busybox
       Image ID:      docker-pullable://busybox@sha256:6915be4043561d64e0ab0f8f098dc2ac48e077fe23f488ac24b665166898115a
       Port:          <none>
       Host Port:     <none>
       Command:
         sh
         -c
         result=1; until [ $result -eq 0 ]; do OK=$(echo ruok | nc -w 1 owdev-zookeeper-0.owdev-zookeeper.openwhisk.svc.kubernetes.default.svc.cluster.local 2181); if [ "$OK" == "imok" ]; then result=0; echo "zookeeper returned imok!"; else echo waiting for zookeeper to be ready; sleep 1; fi; done; echo "Success: zookeeper is up"
       State:          Running
         Started:      Fri, 24 Jan 2020 10:59:56 +0000
       Ready:          False
       Restart Count:  0
       Environment:    <none>
       Mounts:
         /var/run/secrets/kubernetes.io/serviceaccount from default-token-bjt6q (ro)
   ```
   Either zookeeper really isn't ready (in which case debug why zookeeper isn't starting correctly) or the probe in the can't reach zookeeper to get the expected `imok` response (so debug why the network connectivity isn't as expected).
