How to dockerize Jupyter lab

I'm trying to dockerize the Jupyter Lab and so I tried to create a Dockerfile as below,

FROM python:3.6

WORKDIR /jup

RUN pip install jupyter -U && pip install jupyterlab

EXPOSE 8888

ENTRYPOINT ["jupyter", "lab"]


and run the commands, docker build . -t jupyter then docker run jupyter. But unfortunately I got some error as below

[I 07:56:34.123 LabApp] Writing notebook server cookie secret to /root/.local/share/jupyter/runtime/notebook_cookie_secret

    sock.bind(sockaddr)

How can I dockerize jupyter lab ? [ by solving this error ]

You really don't have to roll your own. The Jupyter Docker Stack provides ready-made JupyterLab images that work together with a JupyterHub docker image. The Hub can "spawn" a separate container for each user running a given JupyterLab (search for the DockerSpawner class that's responsible for the magic).

The reason I am adding this as a separate answer is the CAVEAT: while useful links are available on the Internet, they are often outdated and there are inconsistencies between the documentation and reality that make the "productive Dockerisation of Jupyter" rather painful. Just to name a few that I encountered:

  1. If you don't have root privileges on the Docker host, then it'll be rather complicated to add temporary users to the Hub container. I needed this because I am teaching courses where the participants must get temporary accounts which are deleted after the course, and I was not allowed to pollute the Docker host with these accounts.
  2. There is a lot of confusion about the identity of the user logging in to the JupyterHub vs the identity of the user actually running in the JupyterLab container: the latter is always jovyan, UID=1000. This can lead to unexpected surprises regarding file ownerships and permissions.
  3. If the example scripts and datasets shall be "added" to the Lab containers so that every course participant gets a standardised set of files to start working with, then you'll need startup hooks for the copy operation with some interesting requirements. E.g. the copy script must not have the .sh extension because then it's meant to do something different...

YMMV, of course. And despite all this, when it works then it's a rather elegant setup. I am going to try it out for real on some unlucky students soon :-)

As an alternative to building your own Docker image with JupyterLab, you can also use the ML Workspace image. The ML Workspace is an open-source web IDE that combines Jupyter, JupyterLab, VS Code, and many other tools & libraries into one convenient Docker image. Deploying a single workspace instance is as simple as:

docker run -p 8080:8080 mltooling/ml-workspace:latest

All tools are accessible from the same port and integrated into the Jupyter UI. You can find further information on how to access JupyterLab here.

Whilst searching around I came across this question, before going on to discover a reference to Jupyter Labs in the 'Read The Docs' pages for Jupyter Docker Stacks (see here). The documentation says:

JupyterLab is preinstalled as a notebook extension starting in tag c33a7dc0eece.

and they suggest using a command like:

docker run -it --rm -p 8888:8888 jupyter/datascience-notebook start.sh jupyter lab

I thought I might as well add the reference here in case it's useful for others. (It's not immediately obvious on Docker Hub for example, that there is support for Jupyter Labs.)

When you start jupyter lab you should define --ip parameter. For example, --ip=0.0.0.0.

After this you will have another error:

[C 08:14:56.973 LabApp] Running as root is not recommended. Use --allow-root to bypass.

So, if you want to proceed you need to add --allow-root as well.

The final Dockerfile is:

FROM python:3.6

WORKDIR /jup

RUN pip install jupyter -U && pip install jupyterlab

EXPOSE 8888

ENTRYPOINT ["jupyter", "lab","--ip=0.0.0.0","--allow-root"]
