Using a custom docker image to add new packages
In case you are missing some packages from the default application image, you can add those packages yourself.

Typically, the dockerfile looks similar to the following
# The image to use as a base image FROM quay.io/uninett/example-docker-image:20180102-xxxxxxx # Install system packages USER root RUN apt update && apt install -y vim # Install other packages USER notebook RUN pip install scikit-learn
You need to have this image pushed to a public repository e.g. Docker hub or Quay Registry.
Once pushed, you can use the docker image by specifying the

After specifying your custom image and applying those changes, your image will be used in the given instance of application and have all the newly added packages.
