This series was inspired by a recent post from Fabiano to provide container images for migration tests: https://lore.kernel.org/qemu-devel/[email protected]/T/#m353f119dc1a24fa437dde8a96d1891629e64303c
The idea to be able to build and run any QEMU (past) release with containers was in my mind for some time, so I gave it a shot. Finally, it was easier than expected to obtain a single dockerfile (with a few hacks) that works over all our releases. Images have the absolute minimal content possible. It's only qemu binaries, artifacts (roms, keymap, ...), and libraries. There is no shell or any other tool included. As a result, images have a size from 581MB (v3.1.0) to 1.1GB (v11.1.2). This series adds: - a unique dockerfile to build any QEMU release. User has to provide an explicit Ubuntu version when building a given QEMU version. - A script build_release_container.sh which automatically detects which ubuntu version a given release should be buildable on (based on date). It works great, and the heuristic works for all our versions. TLDR: $ ./scripts/build_release_container.sh v3.1.0 $ podman run -it --rm qemu/v3.1.0 qemu-system-arm --version v4 -- - supports build for any version (tag or sha-1) - adds an optional parameter to build_release_container.sh to use an alternative URL for QEMU repo - simplified Dockerfile by supporting any version >= 3.1.0. - removed patch 3 generating wrappers to published docker images v3 -- - extend dockerfile to support ubuntu 12.04, and lower older revision we can build from v1.6.1 to v0.12.0. v2 -- - fix generate_release_links.sh: was missing userns option for podman - dockerfile: cleanup "|| true" and replaced with proper ifs Pierrick Bouvier (2): tests/docker/dockerfiles: add release.docker scripts: add build_release_container.sh scripts/build_release_container.sh | 63 +++++++++++++++++++++++++ tests/docker/dockerfiles/release.docker | 48 +++++++++++++++++++ 2 files changed, 111 insertions(+) create mode 100755 scripts/build_release_container.sh create mode 100644 tests/docker/dockerfiles/release.docker -- 2.43.0
