Docker volumes shared with the Jupyter "lock" the folder - docker

Question

I'm testing Docker Desktop 4.10 on Ubuntu 22.04.
Let's say that I want to run a Jupyter Notebook:
docker run -it \
-v "${PWD}":/home/jovyan/work \
-p 8888:8888 \
jupyter/base-notebook
By doing so, I experience the "Permission denied" error while attempting to create a new notebook in the "work" directory.
Starting the notebook with chown options allows me to solve the problem:
docker run -it \
-v "${PWD}":/home/jovyan/work \
-p 8888:8888 \
--user root \
-e CHOWN_HOME="yes" \
-e CHOWN_HOME_OPTS="-R" \
jupyter/base-notebook
This solution has the drawback of changing the permissions of the folder: I see a padlock on the folder and cannot delete the contents, even after removing the container. In particular, Owner is now "user #100999" and Group "100099".
Looking for alternative solutions with no impact on os-permissions. Thanks

Answer 1

You can tell Docker to use the same owner and group as the directory being mounted.
docker run -it \
-v "${PWD}":/home/jovyan/work \
-p 8888:8888 \
--user "$(stat -c '%u:%g' $PWD)" \
--group-add users \
jupyter/base-notebook
The stat command is used to retrieve the user ID and group ID for the current directory's owner.
