** Description changed: [Impact] Currently the ubuntu-base livecd-rootfs project is used to build tarballs that are the base for building docker/OCI images. The tarballs produced with the ubuntu-base project are modified externally (see https://github.com/tianon/docker-brew-ubuntu-core/blob/master/update.sh ) to create the "official" ubuntu images on dockerhub. When including the ubuntu-oci project into livecd-rootfs, we can build tarballs that already contain the changes that are currently done externally. This has multiple advantages: 1) a Dockerfile using that tarball would no longer have to modify anything (means less layers) 2) publishing new OCI images no longer depends on the external dockerhub image creation. Currently eg. the AWS ECR ubuntu containers depend on the containers from dockerhub. That would be no longer the case with this change 3) Possible faster reaction on CVEs. no longer depending on external processes. [Test Plan] 1) build ubuntu-oci project a) Build a test ubuntu-oci tarball with ubuntu-old-fashioned: ./scripts/ubuntu-bartender/ubuntu-bartender --no-cleanup -- --series impish --image-format plain --project ubuntu-oci --subproject minimized b) create a Dockerfile using the tarball created in step 1): cat << EOF > Dockerfile FROM scratch ADD ubuntu-impish-oci-cloudimg-amd64-root.tar.gz / CMD ["/bin/bash"] EOF c) build the container docker build . d) run something in the container: docker run -it $container-id uname -a e) check the size of the docker image and compare with the image for the same series available on dockerhub 2) build another project (ubuntu-base minimized) - TODO: describe test steps + a) Build a test ubuntu-base minimized project with ubuntu-old-fashioned + b) Start the build [Where problems could occur] This change could break other livecd-rootfs projects which might lead to failed builds. But beside that, there is nothing I can think of that would be affected by this change.
