Since September 2022 this repository is no longer used.
Ubuntu OCI rootfs tarballs are now stored in the Launchpad Git repository https://git.launchpad.net/cloud-images/+oci/ubuntu-base, and PRs to the docker-library/official-images are submitted from the Ubuntu Cloud Images CI/CD.
For information about Ubuntu OCI base images see https://hub.docker.com/_/ubuntu.
Please do not open pull requests to update images. We're super happy to get PRs for anything else other than updating the packages in an image though!
The process for updating the images goes like this:
-
Tarballs are published at https://partner-images.canonical.com/oci/ by Canonical
-
Someone with appropriate permissions runs the https://github.com/tianon/docker-brew-ubuntu-core/actions/workflows/update-branches.yml workflow.
-
This updates each
arch-*branch of https://github.com/tianon/docker-brew-ubuntu-core/ to be one commit ahead of master, that commit adding tarballs/Dockerfiles/manifests/checksums for each supported release of Ubuntu (this is why you pass--single-branchto clone to get this repo, you don't want to be downloading all these tarballs) -
generate-stackbrew-library.shfrom this repo is run on a developer machine to produce a replacement for https://github.com/docker-library/official-images/blob/master/library/ubuntu -
This replacement is proposed as a PR to https://github.com/docker-library/official-images
-
The PR is reviewed, approved and submitted by the official image maintainers (https://github.com/docker-library/official-images/blob/master/MAINTAINERS)
-
Some Jenkins happens
-
The new images are published on https://hub.docker.com
Please feel free to open issues and discuss these images. You can submit pull
requests to update the scripts and image metadata, but submitting pull requests
to the arch-* branches to update the images does not work and only upsets the
pig, or something like that.
