I’ve built an image in which there is a local user foo (uid 1000, gid 1000) running a program.
This piece of code saves data in the directory /home/foo/data of the container.
When mounting the container, I want to persist the data on the machine on which I’m running docker, therefore I’ve used this approach in docker-compose.yml
version: "3.3" services: jupyterlab: image: "my:customimage" container_name: "foo-container" volumes: - "$PWD/data:/home/foo/data"
Two issues occur when running this:
- The container cannot save files in the $PWD/data folder, because it is created at startup by Docker with root ownership
- If I manually change $PWD/data ownership to my user’s (which I would like not to do) foo is still not able to write in there because it has a different uid
Is there a possible approach to accomplish what I’m trying to do?
