      Before this update, if you redeployed a full Elasticsearch cluster, it got stuck in an unhealthy state, with one non-data node running and all other data nodes shut down. This happened because new certificates prevented the Elasticsearch Operator from scaling down the non-data nodes of the Elasticsearch cluster. With this update, Elasticsearch Operator can scale all the data and non-data nodes down and then back up again, so they load the new certificates. The Elasticsearch Operator can reach the new nodes after they load the new certificates.

    Description

      On Cert expiry the elasticsearch-operator restarts the whole cluster by scaling down all nodes and then scaling them up again. This causes the restarted nodes to read the generated certificates. However, when the Elasticearch CR includes a node specification for non data nodes, the restart is stuck restarting the non-data nodes.

      Expected Behavior:

      • Scale down all ES nodes regardless roles
      • Scale up all the ES nodes loading the new certificates regardless roles.
