Let's add Fedora multiarch containers to your CI

Sign up or log in to save this to your schedule, view media, leave feedback and see who's attending!

An introduction about multiarch project [1] to enable users to build, run and test Fedora multi arch (aarch64, 390x and etc) containers on your host architecture x86_64 easily.

Multiarch project is a collection of tools to emulate different architecture containers by QEMU and binfmt_misc and the compatible container images.

I also compare it with similar technologies docker buildx and podman buildx being developed by buildash and podman team.
