Create base image for JHubs #4

eeholmes · 2024-01-17T16:33:24Z

Goal: I am creating a base image for various hubs I will be setting up. Set-up needs to match other likely hub images that users might use (so common default JupyterHub images) and images should also work fine for other ways of using them (like binder but my image is kind of big so not really for binder). Some features of images I am trying to replicate

base image will have JLab, RStudio, VSCode but not be customized for geospatial
base image will have the basic apt packages that one expects
conda environment and the jupyter packages are in the "notebook" conda environment.
standard set of jupyterlab packages (extensions) that are found in the Openscapes image
base images uses rocker scripts

Where I am at

A simple Dockerfile with RStudio and jovyan as the user.
create a draft install_mamba.sh or install_conda.sh script. This would both install conda but also include the code needed to make RStudio recognize the activated conda environment.
update the base image to include conda notebook environment for jupyterlab as is standard/common for images designed for jupyterhubs.
