OK, I will do that, thanks!

I had the same issue on Kubernetes using StatefulSet. The fix which worked and still works for me, looks like:

```
# Source: elk/templates/02-elasticsearch-configmap.yaml
apiVersion: v1
kind: ConfigMap
metadata:
  name: elasticsearch-config
  namespace: transactions-api
data:
  elasticsearch.yml: |2+
    cluster.name: "po"
    cluster.initial_master_nodes:
    - elasticsearch-po-0
    - elasticsearch-po-1
    - elasticsearch-po-2
    - elasticsearch-po-3
    - elasticsearch-po-4
    - elasticsearch-po-5
    node.name: ${HOSTNAME}
    # 512Mb per shard being indexed. 2xprimary,2xreplica = 2048Mb
    # https://www.elastic.co/guide/en/elasticsearch/reference/current/indexing-buffer.html
    indices.memory.index_buffer_size: 25%
    indices.memory.min_index_buffer_size: 96mb
    indices.memory.max_index_buffer_size: 2048mb
    thread_pool.write.queue_size: 400

    cluster.routing.allocation.awareness.attributes: rack_id
    cluster.routing.allocation.awareness.force.rack_id.values: 1,2

    xpack.monitoring.collection.enabled: true
    # Disabling unused x-pack components (some are disabled by default)
    xpack.security.enabled: false
    xpack.security.audit.enabled: false
    # ML stuff enabled by default
    xpack.ml.enabled: false
    node.ml: false

    network.host: _site_,_lo_
    # TODO: dynamic configuration needed
    discovery.zen.ping.unicast.hosts:
    - elasticsearch-po-0.elasticsearch-po
    - elasticsearch-po-1.elasticsearch-po
    - elasticsearch-po-2.elasticsearch-po
    - elasticsearch-po-3.elasticsearch-po
    - elasticsearch-po-4.elasticsearch-po
    - elasticsearch-po-5.elasticsearch-po

```

The issue was that ES can't resolve the hostnames like `elasticsearch-po-5`, it can only resolve these: `elasticsearch-po-5.elasticsearch-po`. And since `node.name` is `elasticsearch-po-5` it didn't work. And I was getting the similar name mismatch error. I guess it could be set up more clean than in my case.

If needed I can attach my helm template file as well.

I deployed it in Docker Swarm, to fix this issue, I separated ES into 3 coordination nodes, 3 master nodes, 3 data nodes. and then deploy 3 master nodes in 'replicated' mode instead of "global", then set "initial\_master\_nodes" with master service name. now it works fine.
