Fix #610 - [x] Native cross-compilation support in Dockerfile. Only `linux/amd64` and `linux/arm64` supported and tested (Tier 1 platform support from Rust) - [x] Cache support for cargo downloads and compilation results in Dockerfile - [x] Open Container's [annotations](https://github.com/opencontainers/image-spec/blob/main/annotations.md) in Dockerfile - [x] GitHub Actions workflow to build the image for both platforms, publishing to ghcr.io on tags and master branch pushes. - [x] Disable use of GitHub Actions cache for tags build, allow manually triggering the workflow with or without cache. - [x] [Attestation artifacts](https://docs.github.com/en/actions/security-for-github-actions/using-artifact-attestations/using-artifact-attestations-to-establish-provenance-for-builds) for builds - [x] Add basic informations about the use of the Docker image in README I also changed the WORKDIR from `/src` to `/work`, because if got me confused with the use of the src folder for the project source in the first stage of the Dockerfile. It doesn't impact anything anyways since you can mount the file where you want and have the program options point to it. **How to test?** _After checking out the branch and making sure you have QEMU installed to build/test_ ```shell # Docker sadly doesn't have yet the way to have locally a tag with multiple platforms # despite being able to pass multiple platforms to the build command, so we have to use two distinct tags. docker build --platform=linux/amd64 --tag test-oxipng-amd:latest --load . docker build --platform=linux/arm64 --tag test-oxipng-arm:latest --load . docker run --rm test-oxipng-amd:latest --version docker run --rm test-oxipng-arm:latest --version # Run on some files docker run --rm -it -v $(pwd):/work test-oxipng-amd:latest -a /work/tests/files/apng_file.png docker run --rm -it -v $(pwd):/work test-oxipng-arm:latest -a /work/tests/files/apng_file.png # Remove the images docker image rm test-oxipng-amd:latest docker image rm test-oxipng-arm:latest ``` For the workflow, see the GitHub Actions logs. If you want to test the ghcr.io publishing you can merge the branch into a fork and see the result. --------- Co-authored-by: Alejandro González <me@alegon.dev>
