HiveMQ Commercial Offerings HiveMQ k8s Operator

I have tried to add below parameters in deployment manifest but getting “Read-only file system” error in pods logs.

    volumeMounts:
    - name: hivemq-volume-2
      mountPath: /opt/hivemq/conf/config.xml
      subPath: config.xml
  volumes:
  - name: hivemq-volume-2
    configMap:
      name: hivemq-config

Getting below error in hivemq pod logs after deployment.

Getting bind address from container hostname
set bind address from container hostname to 10.47.0.1
chown: changing ownership of ‘/opt/hivemq/conf/config.xml’: Read-only file system
