Nodered docker image in Azure IoT Edge device

I downloaded the github project of docker nodered image (Docker Hub) and modified by adding node red opcua library in package.json and adding few environment variables.

After that I built the image using docker-debian.sh in docker-custom folder and pushed it to azure container registry.

Then I added this image as a Azure IOT edge device module and it shows running and flows are started but cannot access the nodered GUI.

I created a Azure web app using the same image and it is working as expected and can access nodered GUI.

Please confirm whether we can use this docker image as a Azure IoT edge module
