Multi-Arch container (to run on RaspberryPi)

[odin568]

Hi @JasperE84 ,
stumbled over this project and is exactly what i need :-)

Anyhow, I run my containers on a RaspberryPi being arm64 architecture. I would like to support in extending github action but I don't see how you so far pushed the containers to dockerhub.

From what I see, this should be quite easily achievable with classical multi stage build like this

name: Docker Image CI

on:
  push:
    branches: [ "main" ]
  pull_request:
    branches: [ "main" ]

jobs:
  build:
    runs-on: ubuntu-latest

    steps:
    - uses: actions/checkout@v4

    - name: Set up QEMU
      uses: docker/setup-qemu-action@v3

    - name: Set up Docker Buildx
      uses: docker/setup-buildx-action@v3

    - name: Login to Docker Hub
      uses: docker/login-action@v3
      with:
        username: ${{ secrets.DOCKERHUB_USERNAME }}
        password: ${{ secrets.DOCKERHUB_TOKEN }}

    - name: Build and push multi-arch image
      uses: docker/build-push-action@v6
      with:
        context: .
        file: ./Dockerfile
        platforms: linux/amd64,linux/arm64
        push: true
        tags: |
          docker.io/${{ secrets.DOCKERHUB_USERNAME }}/pyfusionsolardatarelay:latest
          docker.io/${{ secrets.DOCKERHUB_USERNAME }}/pyfusionsolardatarelay:${{ github.sha }} # example

Thanks for feedback :-)

You may look into my fork so far. Pushed it for myself for now
