Currently, we have 1100~ cache images uploaded to GHCR that weigh more than 300 MB each (most of them are layers from the second phase of the Dockerfile that were uploaded by mistake, read below). To avoid problems, I have set up a new job in a new workflow to be run weekly purging all images older than 1 week, but leaving always the 100 most recent ones.
Only the builder images should be uploaded to cache, the actual behaviour not only slows down the time for building the container, but also wastes lots of space by saving large and useless layers to GHCR that will never be used again.
container.yml will run after integration.yml COMPLETES successfully and in master branch.
Style changes, cleanup and improved integration with CI by leveraging the use of
shared cache between all workflows.
* Podman is now supported to build the container images (Docker also received a refactor, merging both build and buildx)
* Container images are being built by Buildah instead of Docker BuildKit.
* Container images are tested before release.
* Splitting "modern" (amd64 & arm64) and "legacy" (armv7) arches on different Dockerfiles allowing future optimizations.
