JupyterHub, the multi-user server that gives each user their own Jupyter notebook server, here as the hub with KubeSpawner (notebooks as pods) and OAuthenticator (GitHub, GitLab, Google, generic OIDC). Packaged from PyPI on Wolfi python-3.13; pairs with configurable-http-proxy.

Version

0.0.11 · latest0.0.100.0.9

The latest line lives at the base page; older lines have their own page so you can pin and verify exactly that version. Only the most recent releases are listed — an older chart pins an older image digest.

Transparency

The chart publishes its attestations on GitHub and the image it deploys carries its own on the same digest, publicly verifiable with the commands above. Both log to the Sigstore transparency log (Rekor), which cosign verify checks for you.
