  Kafka cluster as Kubernetes StatefulSet, plain manifests and config

  

We are using a Apache-Kafka deployment on Kubernetes which is based on the ability to label pods after they have been created (see https://github.com/Yolean/kubernetes-kafka). The init container of the broker pods takes advantage of this feature to set a label on itself with its own numeric index (e.g. "0", "1", etc) as value. The label is used in the service descriptors to select exactly one pod.

This approach works fine on our DIND-Kubernetes environment. However, when tried to port the deployment onto a Docker-EE Kubernetes environment we ran into trouble because the command kubectl label pod generates a run time error which is completely misleading (also see https://github.com/fabric8io/kubernetes-client/issues/853).
