@carlallen Is this working for you well? I've ran into https://forum.gitlab.com/t/container-registry-docker-buildx-support/52468/2

I don't do multi-arch builds, I use other expirimental features in buildx

I was referring more to the cache image. Any issues there?

Oh, I feel like making new cache images is weird since something changed, but I haven't done that in a while. I do know that cache images can not be deleted in the registry unless you push a real image over the same tag and then delete it.

Interesting... Thanks for the info!

Thank you very much! For a long time I was puzzled about how to generate an image for ARM64 and AMD64, I ended up getting it this way:

build:
  stage: build
  services:
    - name: docker:dind
      command: ["dockerd", "--host=tcp://0.0.0.0:2375"]
      alias: 'docker'
  image: carlallen/docker:buildx
  before_script:
    - docker buildx create --driver=docker-container --name=buildkit-builder --use
    - docker login -u gitlab-ci-token -p $CI_JOB_TOKEN registry.gitlab.com
  script: |
    docker buildx build \
          --cache-from type=registry,ref=$CI_REGISTRY_IMAGE:cache \
          --cache-to type=registry,ref=$CI_REGISTRY_IMAGE:cache \
          --platform linux/arm64,linux/amd64 \
          --push \
          --tag $CI_REGISTRY_IMAGE:latest \
          .

sadly carlallen/docker:buildx seems to be gone 😞

Yeah, I did a docker cleanup and I haven't been keeping that image up to date. I think this image should work: https://hub.docker.com/r/snickch/buildx

Thank you for the response!

.docker_build_img:
  # The stage must come before the stage in which the step is needed
  stage: build
  image: docker:latest
  services:
    - docker:dind
  before_script:
    - docker version
    - docker info
    - docker buildx create --driver=docker-container --name=buildkit-builder --use
  script:
    - echo -n $CI_JOB_TOKEN | docker login -u gitlab-ci-token --password-stdin $CI_REGISTRY
    - docker pull $IMGNAME:latest || true
    - docker buildx build . --platform linux/arm/v7 -f $DOCKERFILE --cache-from $IMGNAME:latest -t $IMGNAME:$TAG --load
    - docker push $IMGNAME:$TAG

This ended up working for me as well.
