Docker buildx bake - The Sequel

[back-2-95]

• 2 distros: bullseye and alpine 3.17
• Main Dockerfile + distro specific builder dockerfiles
• Bake definition file which can be extended to more PHP versions and distros
• .dockerignore file updated
• Simple buildx bake GHA workflow (no push enabled, just showing) See run: https://github.com/back-2-95/frankenphp/actions/runs/3917789332/jobs/6697797558
• Supersedes WiP: One Dockerfile to rule them all #64

TODO / TBD

• Add Docker Hub log into GHA workflow and enable push
• Builder dockerfiles can be also combines into one multistage dockerfile

Notes

• Uses named build contexts introduced in buildx 0.8.0 - No more ARGS

Testing

Show what is about to go down:

docker buildx bake -f docker-bake.hcl --print

Build all images locally for arm64 arch (with --load and --set "*.platform=linux/arm64" flags):

docker buildx bake -f docker-bake.hcl --pull --load --set "*.platform=linux/arm64"

Same as previous but build only 1 target from docker-bake.hcl:

docker buildx bake -f docker-bake.hcl --pull --load --set "*.platform=linux/arm64" bullseye

Build locally and override image name:

IMAGE_NAME=my/frankenphp docker buildx bake -f docker-bake.hcl --pull --load --set "*.platform=linux/arm64" --progress plain

Build and push all images with override image name (needs you logged in to Docker Hub or some other registry):

IMAGE_NAME=my/frankenphp docker buildx bake -f docker-bake.hcl --pull --push

We need to continue running the tests somewhere in the CI.

[back-2-95]

Yes, this is just that I need help with this one.

[dunglas]

Can you add a comment explaining why it's necessary please?

[back-2-95]

Separate file or what?

[dunglas]

I don't understand what it's doing :D

[dunglas]

@back-2-95 I would really like to get this PR merged! Is there anything I can do to help?

[dunglas]

I rebased your branch and fixed and issue with the Dockerfile versions.
