elek commented on issue #945: HDDS-1646. Support real persistence in the k8s example files URL: https://github.com/apache/hadoop/pull/945#issuecomment-500825750 I created a new kubernetes cluster definition (`getting-started`). After this patch we will have the following resources: * minikube (for Minkube usage, ephemeral) * getting-started (for real kubernetes cluster, ephemeral) * ozone (for normal use-cases, real persistence) * ozone-dev (for development and performance test, ephemeral by default) * I created rules to add LocalPersistentVolume based PVC * I removed the support of daemonset based datanodes as it's not possible to support PVs * I added pod antiAffinity rules to ensure that the statefulset based pods are scheduled to different nodes * securityContext/fsGroup is used to make sure that we have permission to write the volumes
