[FEAT] Run on Kubernetes with config map for ddclient.conf file

[marleixo]

Is this a new feature request?

• I have searched the existing issues

Wanted change

I'm moving my stuff to Kubernetes and while moving this I don't want to have to create a volume for it but only creating a configmap, it's a configuration file and it makes sense to be a configmap instead of giving it a volume only for a config file.

Reason for change

it's a configuration file and it makes sense to be a configmap instead of giving it a volume only for a config file.
I tried doing it, but it's trying to change the owner of the file some some reason

chown: changing ownership of '/config/ddclient.conf': Read-only file system
**** Permissions could not be set. This is probably because your volume mounts are remote or read-only. ****
**** The app may not work properly and we will not provide support for it. ****
chmod: changing permissions of '/config/ddclient.conf': Read-only file system
s6-rc: warning: unable to start service init-ddclient-config: command exited 1

This is what I did as a workaround. Note that this will not capture upstream changes on the run shell script so you will want to pin the version of the container and review any upstream changes if you update it. This will allow you to not have to build your own Docker image.

    spec:
      volumes:
        - name: ddclient-config-file
          secret:
            secretName: ddclient-secret
        - name: run
          emptyDir: {}
      containers:
        - name: ddclient
          image: linuxserver/ddclient:4.0.0
          imagePullPolicy: Always
          command: ["/bin/bash"]
          args: ["-c", "echo -e \"#!/usr/bin/with-contenv bash\nmkdir -p /run/ddclient-cache /run/ddclient && chmod 700 /config /run/ddclient-cache;\" > /etc/s6-overlay/s6-rc.d/init-ddclient-config/run && /init"]
          env:
            - name: LSIO_NON_ROOT_USER
              value: "true"
          volumeMounts:
            - mountPath: /config/ddclient.conf
              subPath: ddclient.conf
              name: ddclient-config-file
            - mountPath: /run
              name: run

I really would love this to happen but my last attempt was shot down by the maintainers sadly if memory serves correctly...
