S2I Minimal Notebook

Minimal Thoth S2I notebook builder

This repository is a Fork of Graham Dumpleton: jupyter-on-openshift/jupyter-notebooks.

This repository contains Source-to-Image (S2I) build process to create a Minimal Jupyter Notebooks on OpenShift. The image can be built in OpenShift, separately using the s2i tool, or using a docker build. The same image, can also be used as an S2I builder to create customised Jupyter notebook images with additional Python packages installed, or notebook files preloaded.

Note: When using Minimal Thoth S2I notebook build process, it is required to use .thoth.yaml file even if all the Thoth features are turned off. A simple .thoth.yaml file as generated by thamos config should work in most cases (see thamos repository for more info).

Importing the Minimal Notebook

A pre-built version of the minimal notebook which is based on Thoth Ubi8 Images, can be found at on quay.io at:

Image Status
ubi8-py3.6 Docker Repository on Quay
ubi8-py3.8 Docker Repository on Quay
ubi8-py3.9 Docker Repository on Quay
ubi9-py3.9 Docker Repository on Quay
f34-py3.9 Docker Repository on Quay
f35-py3.10 Docker Repository on Quay

This image could be imported into an OpenShift cluster using OpenShift ImageStream:

apiVersion: image.openshift.io/v1
kind: ImageStream
metadata:
  # (Below label is needed for Opendatahub.io/JupyterHub)
  # labels:
  #   opendatahub.io/notebook-image: "true"
  name: s2i-minimal-notebook
spec:
  lookupPolicy:
    local: true
  tags:

    from:
      kind: DockerImage
      name: quay.io/thoth-station/s2i-minimal-notebook:latest

Building the Minimal Notebook

Instead of using the pre-built version of the minimal notebook, you can build the minimal notebook from source code. we follow overlay based method in s2i-minimal-notebook build. A tool Thamos is used for the installation of python stacks.Details about the tool can be found at Thamos Documentation

  • Build python36 from the overlay/python36 by setting the environment variable THAMOS_RUNTIME_ENVIRONMENT=python36

    s2i build . quay.io/thoth-station/s2i-thoth-ubi8-py36:latest \
    --env ENABLE_PIPENV=1 \
    --env THAMOS_RUNTIME_ENVIRONMENT=python36 \
    --env THOTH_ADVISE=0 \
    --env THOTH_ERROR_FALLBACK=1 \
    --env THOTH_DRY_RUN=1 \
    --env THOTH_PROVENANCE_CHECK=0 \
    s2i-minimal-notebook

    Thoth advise provides recommendation for python stack directly during the build time.
    It can be used by setting the environment variable THOTH_ADVISE=1

    s2i build . quay.io/thoth-station/s2i-thoth-ubi8-py36:latest \
    --env ENABLE_PIPENV=1 \
    --env THAMOS_RUNTIME_ENVIRONMENT=python36 \
    --env THOTH_ADVISE=1 \
    --env THOTH_DRY_RUN=0 \
    --env THOTH_PROVENANCE_CHECK=1 \
    s2i-minimal-notebook
  • Build python38: From the overlay/python38 by setting the environment variable THAMOS_RUNTIME_ENVIRONMENT="python38" in the Dockerfile

    podman build -t s2i-minimal-py38-notebook -f overlays/python38/Dockerfile .
