I need to edit the log4j configuration in log4j.properties, the file is editible if I exec into it but the changes dont persist accross pod restarts. Is there a way to configure this through the operator or a yaml file?

The `log4j2.properties` configuration file is part of the container and is ephemeral as any file that is not mounted in a volume.

If you want to change the logging levels I would suggest to first try to use the command-line options or use the cluster settings as described in the [Elasticsearch documentation](https://www.elastic.co/guide/en/elasticsearch/reference/master/logging.html#configuring-logging-levels).

If you really know what you are doing you can override the log4j2 configuration using a configMap with something like:

```auto
$ kubectl create configmap log4j --from-file=log4j2.properties=/path/to/my/log4j2.properties

```

Then mount the configmap:

```auto
    podTemplate:
      spec:
        containers:
        - name: elasticsearch
          volumeMounts:
          - mountPath: /usr/share/elasticsearch/config/log4j2.properties
            subPath: log4j2.properties
            name: log4j
        volumes:
        - name: log4j
          configMap:
            name: log4j

```
