What is this?

Run JupyterLab with Docker Compose, with integrated support for other languages: C, Kotlin, Bash, and JavaScript.

Who is it for?

Anyone trying to understand how to install alternative kernels in order ot get support for programming languages other than Python in JupyterLab.

Setup

1. Edit docker-compose.yml and replace:

   • existing-docker-network
   • /path/to/jupyter/notebooks: A directory with your .ipynb notebooks, typically a Git repo. Its root will show up in the sidebar.¹
   • /path/to/jupyter/configuration: Settings and cache. For rootless Docker, change this directory's ownership on the host to 100999:100099 (it's not a typo).¹

2. Run docker compose up -d --build.

3. The default port is 8888.

4. Install additional Python packages by adding them to the # install Python packages section of the Dockerfile, then rebuild.

Make password persistent across server sessions

1. Run docker logs jupyter and copy the token.
2. Fill in the form, including your new password.
3. Follow the instructions in /path/to/jupyter/configuration/jupyter_server_config.py:c.ServerApp.password; ignore DEPRECATED warnings.
