[FIXED] Running Raku notebook in Docker

Issue

Running Raku (previously aka Perl 6) kernel in Jupyter notebook would be great for reproducibility and ease of use (personal view).

I wanted to run the Perl 6 notebook in a docker container and access it in my web browser. For this I created this docker image.

The code to create the docker image was:

FROM sumankhanal/rakudo:2019.07.1

RUN apt-get update \
    && apt-get install -y ca-certificates python3-pip && pip3 install jupyter notebook \
    && zef install Jupyter::Kernel --force-test

ENV TINI_VERSION v0.6.0
ADD https://github.com/krallin/tini/releases/download/${TINI_VERSION}/tini /usr/bin/tini
RUN chmod +x /usr/bin/tini
ENTRYPOINT ["/usr/bin/tini", "--"]

EXPOSE 8888
CMD ["jupyter", "notebook", "--port=8888", "--no-browser", "--ip=0.0.0.0"]

I am on Windows 10 64 bit and IP address of my docker is 192.168.99.100.

When I tried to run the container with this code:

docker run -it -p 8888:8888 sumankhanal/raku-notebook in the docker terminal

I get this error:

$ docker run -it -p 8888:8888 sumankhanal/raku-notebook

Any help ?

Solution

You need to add --allow-root in the CMD of your Dockerfile. Also you need to link the kernel with jupyter in your dockerfile

jupyter-kernel.p6 --generate-config

Once you do that you will be able to see the dockerfile. I also noticed that your images size is very huge, you should try and find a better base image for jupyter rather than the one you have.

For more details about installing kernels refer to the below link
