I am trying to mount elasticsearch.yml from my kubernetes configmap as follows but the `elastic-internal-init-filesystem` init container is throwing error.  
Error

```auto

          subPath: log4j2.properties
      volumes:
      - configMap:
          name: elasticsearch-config
        name: config
      

```

It seems that internally elasticsearch.yml is getting mounted. How can I update the yml since it is a big file.

Hi Aman,

I also replied to you Slack DM.

You shouldn't mount `elasticsearch.yml` when using ECK.

You are supposed to make these changes in the deployment as following:  
[https://www.elastic.co/guide/en/cloud-on-k8s/current/k8s-node-configuration.html](https://www.elastic.co/guide/en/cloud-on-k8s/current/k8s-node-configuration.html)

Hope it makes sense

Thanks
