4. Check $HOME

I think you're checking it wrong.
You are probably doing docker exec -it CONTAINER_ID bash and then echo $HOME.
This way it will indeed show /home/jovyan.
The reason for this is that the Dockerfile was built with ENV /home/jovyan.
I think there is no way to change during runtime the env variable saved for the image, so it will stay like this.

I checked Jupyter Terminal and Jupyter Lab (notebook) - and $HOME is /home/root in both cases, which is correct.

@anil-resero
If you really need to have $HOME to be /home/root when running docker exec commands, then I suggest you create your own Dockerfile like this:

FROM quay.io/jupyter/datascience-notebook:2024-01-16
ENV HOME=/home/root

Then just build and use this image.

I have tested this and it works:

docker build -t test .
docker run -it --rm --user root -p 8888:8888 -e NB_UID=0 -e NB_GID=0 -e NB_USER=root -e NOTEBOOK_ARGS="--allow-root" test

Then it shows /home/root even in docker exec ...

@anil-resero Did you docker exec -ti happy_sutherland bash into the container?
