I have built a Dockerfile from an official image of Nodered and added some custom nodes. After build I ran a Docker container which runs fine and show the custom nodes I added. Now I pushed the custom image to a private registry and when using it in a kubernetes deployment pods runs fine but the custom nodes are not shown in the Nodered UI.

I have exec into both Docker container and k8s pod to see what was going on and found that the folder 'files' I passed in the Dockerfile to folder /data exists only in the Docker container, it isn´t in the K8s pod.

Here is the folder 'files'in Docker:

docker exec -ti ca55c5823200 bash
bash-5.0# cd /data
bash-5.0# ls
files              flows.json         lib                node_modules       package-lock.json  package.json       settings.js

Now when I exec into the K8s pod:

bash-5.0# cd /data
bash-5.0# ls
config        lib           lost+found    node_modules  package.json  settings.js
bash-5.0# 

I also checked the pod logs but found nothing useful:

k logs nodered-696bc98c7f-c48h7

> node-red-docker@1.3.6 start /usr/src/node-red
> node $NODE_OPTIONS node_modules/node-red/red.js $FLOWS "--userDir" "/data"

---------------------------------------------------------------------
Your flow credentials file is encrypted using a system-generated key.

If the system-generated key is lost for any reason, your credentials
file will not be recoverable, you will have to delete it and re-enter
your credentials.

You should set your own key using the 'credentialSecret' option in
your settings file. Node-RED will then re-encrypt your credentials
file using your chosen key the next time you deploy a change.

This is the Dockerfile:

FROM nodered/node-red:1.3.6-12
USER root
COPY files/settings.js /data/
COPY files/ /data/files
RUN chown -R node-red:root /data
RUN bash /data/files/script.sh 

And this is the Deployment manifest:

apiVersion: apps/v1

  selector:
    matchLabels:
      app: nodered

          persistentVolumeClaim:
            claimName: nodered-pvc
      restartPolicy: Always

Any idea what is going on? Thank you in advanced!

After seeing David's comment below I have removed the PV and PVC from the deployment manifest and now I see these syntax errors in the logs. What I don't get is why it is running fine in Docker:

k logs nodered-6cdd6954f6-pmgmf

/data/settings.js:347
    }
    ^
