An incomplete base Docker image for running JupyterHub

Add your configuration to create a complete derivative Docker image.

Include your configuration settings by starting with one of two options:

Option 1:

FROM jupyterhub/jupyterhub:latest

And put your configuration file jupyterhub_config.py in /srv/jupyterhub/jupyterhub_config.py.

Option 2:

Or you can create your jupyterhub config and database on the host machine, and mount it with:

docker run -v $PWD:/srv/jupyterhub -t jupyterhub/jupyterhub

NOTE

If you base on jupyterhub/jupyterhub-onbuild

your jupyterhub_config.py will be added automatically

from your docker directory.

This Dockerfile uses multi-stage builds with optimisations to build

the JupyterHub wheel on the native architecture only

https://www.docker.com/blog/faster-multi-platform-builds-dockerfile-cross-compilation-guide/

ARG BASE_IMAGE=ubuntu:22.04

######################################################################

The JupyterHub wheel is pure Python so can be built for any platform

on the native architecture (avoiding QEMU emulation)

FROM --platform=${BUILDPLATFORM:-linux/amd64} $BASE_IMAGE AS jupyterhub-builder

ENV DEBIAN_FRONTEND=noninteractive

Don't clear apt cache, and don't combine RUN commands, so that cached layers can

be reused in other stages

RUN apt-get update -qq
&& apt-get install -yqq --no-install-recommends
build-essential
ca-certificates
curl
locales
python3-dev
python3-pip
python3-pycurl
python3-venv
&& python3 -m pip install --no-cache-dir --upgrade setuptools pip build wheel

Ubuntu 22.04 comes with Nodejs 12 which is too old for building JupyterHub JS

It's fine at runtime though (used only by configurable-http-proxy)

RUN curl -fsSL https://deb.nodesource.com/setup_18.x | bash -
&& apt-get install -yqq --no-install-recommends
nodejs
&& npm install --global yarn

WORKDIR /src/jupyterhub

copy everything except whats in .dockerignore, its a

compromise between needing to rebuild and maintaining

what needs to be part of the build

COPY . .

ARG PIP_CACHE_DIR=/tmp/pip-cache RUN --mount=type=cache,target=${PIP_CACHE_DIR}
python3 -m build --wheel

######################################################################

All other wheels required by JupyterHub, some are platform specific

FROM $BASE_IMAGE AS wheel-builder

ENV DEBIAN_FRONTEND=noninteractive

WORKDIR /src/jupyterhub

COPY --from=jupyterhub-builder /src/jupyterhub/dist/.whl /src/jupyterhub/dist/ ARG PIP_CACHE_DIR=/tmp/pip-cache RUN --mount=type=cache,target=${PIP_CACHE_DIR}
python3 -m pip wheel --wheel-dir wheelhouse dist/.whl
