I built an image in this directory: docker build -t custom-notebook-server . Then I tried to run it: docker run --rm -it custom-notebook-server

But it gives me an error:

Is it normal behaviour? Because I can't configure jupyterhub to start a custom container for users and probably problem in this Dockerfile.

I have this error when I try to launch a custom-notebook-image from examples folder.

[W 2019-12-23 19:14:00.701 JupyterHub web:1667] 500 GET /hub/user/kenenbek/ (::ffff:92.242.58.11): Spawner failed to start [status=ExitCode=1, Error='', FinishedAt=2019-12-23T19:13:51.834730009Z]. The logs for kenenbek may contain details.

The default image is working but the error happens when I change the environmental variable DOCKER_NOTEBOOK_IMAGE and .env file to the custom one.

your custom image needs to play nice with what's expected. meaning, you need to have the exact right jupyterhub version installed, notebook, lab (optional?), etc. the dockerfiles in the jupyter/docker-stacks repo are of help. When I base builds FROM one of those, things generally work pretty well (notwithstanding hub version mismatches)

Hi :wave: This is an old issue and the repository has been updated. If you have more questions please use the Jupyter community forum https://discourse.jupyter.org/.
