ubuntu is @SGSGermany's base image for containers based on Ubuntu. This image is built daily at 21:20 UTC on top of the official Docker image using GitHub Actions.
Rebuilds are triggered only if Ubuntu builds a new image, or if one of the ubuntu-oci base packages were updated. Currently we create images for both Ubuntu 24.04 "Noble Numbat" and Ubuntu 22.04 "Jammy Jellyfish". Please note that we might add or drop branches at any time, but usually around upstream's release resp. end-of-life dates.
All images are tagged with their Ubuntu version string, build date and build job number (e.g. v22.04-20190618.1658821493.1), as well as with the release branch's short codename (e.g. jammy-20190618.1658821493.1). The latest build of an Ubuntu release is additionally tagged without the build information (e.g. v22.04 and jammy). The latest build of the latest Ubuntu LTS release is furthermore tagged with latest.
