Hi,

Thanks a lot for creating the slim alpine images for Docker. Would it be possible for you to add support for Arm64/v8 arch? I've an Apple Silicon M1 macbook and other images don't work on it.

I tried forking this repo, but didn't go far as there are a lot of changes required with credentials etc.

We could leverage the platforms argument of the Docker buildx action?

 - name: Build Android Base JDK${{ matrix.jdk }}
   uses: docker/build-push-action@v2
   with:
     context: ./docker
     file: ./docker/base.Dockerfile
     push: true
     tags: ${{ steps.docker_meta.outputs.tags }}
     build-args: |
       JDK_VERSION=${{ matrix.jdk }}
     # Limit to platforms supported by base image
     platforms: |
       linux/arm64/v8

Here is a PR the has the relevant build .yml file that builds for arm64/v8 arch:
