CentOS systemd Jupyter Notebook

Notebook for running bash in JupyterHub with a CentOS 7 System image.

This is based on https://github.com/jupyter/docker-stacks/tree/ede5987507cfb52a70e0909f321baf4b059c2add/base-notebook

Includes an example of installing OMERO with Ansible.

Usage

Generate a secure access token. Run the container:

JUPYTER_TOKEN=$(env LANG=C tr -dc A-Za-z0-9 < /dev/urandom | head -c 32)
docker run -d --name jupyter-notebook \
    -p 8888:8888 -p 8080:80 -p 4064:4064 \
    -e JUPYTER_TOKEN=$JUPYTER_TOKEN centos-systemd-jupyter-notebook

Open the notebook server in your browser:

echo http://localhost:8888/?token=$JUPYTER_TOKEN

Open omero-server-bash.ipynb in the notebooks directory.

Shell kernel

The Bash kernel is installed. The default jovyan user has password-less sudo rights.

Technical notes

systemd normally requires elevated privileges to run inside Docker. This image uses a a substitute systemctl script so it can be run as a normal container. This means the behaviour is not identical to the original systemd/systemctl commands, but it should be adequate for testing with Docker.

WARNING If you subsequently upgrade systemd it will overwrite the substitute script. If you see an error like Failed to get D-Bus connection: Operation not permitted this is probably the cause. Rebuild the container (with --no-cache if necessary) so that systemd will be updated before systemctl is modified.
