How to dockerize Jupyter lab

Question

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

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

Answer 1

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"]
