Add cleanup_repos to revert build_only overrides

2026-08-05T08:13:09+00:00

Repos marked build_only: true are backed up before handle_repos() overwrites them and restored at the end of each image build, so CI mirror URLs are not baked into the final image. The cleanup RUN was injected into every Dockerfile, not just images that called handle_repos() for those repos. Child images with no backup fell through to "rm -f", deleting the inherited repo file (e.g. debian.sources in bifrost-base, breaking cpio install). Fix by adding a {repo}.enabled sentinel that handle_repos creates when it processes a build_only repo, making the cleanup conditional on that sentinel.

kolla-build: fix build-date LABEL invalidating Docker layer cache

2026-06-24T13:00:26+00:00

The build-date label was rendered into a LABEL instruction on line 3 of every Dockerfile template, immediately after FROM. Because Docker invalidates the cache for a changed instruction and all subsequent layers, a date change caused a full rebuild of every image on each new calendar day, even when nothing else had changed. Fix this by removing build-date from the Dockerfile templates and applying it as a --label argument at build time via image.labels. Labels passed on the build command line are not part of the Dockerfile cache key, so the date is still recorded in the image metadata without affecting layer caching.

kolla-build: Add Docker BuildKit support via docker buildx build

2026-06-18T08:54:32+00:00

Add --buildkit flag to use docker buildx build instead of the docker-py SDK. An optional --buildkit-builder selects a named buildx builder instance, enabling docker-container or remote drivers for multi-arch builds. --buildkit and --squash are mutually exclusive and rejected at startup. PushTask is skipped when buildkit is active; push is handled inline. Set buildkit as the new default. Change-Id: Idbf1d1bdc091bb84721f8006c2b916731b999859 Signed-off-by: Michal Nasiadka
