Run ARM Docker images in GitHub Actions runners!	2022-01-17 16:53:00	run-arm-docker-images-in-github-actions-runners	/images/translation.jpg	Want to build ARM-compatible Docker images in GitHub Actions without banging against a wall? Read this post for the fix.	docker containers lxc linux containerization devops github github actions devops ci/cd ci cd

This is so easy to do, I think I can describe it in less than 150 words!

Problem: You want to run Docker images from Docker images that target ARM, or you want to build images for ARM platforms.

Solution: Add this to .github/workflows/main.yml (or whichever YAML file you'd like to enable ARM support for):

jobs:
  your-job-name:
    steps:
      # Add this to the top of your `steps`
      - name: Set up QEMU - arm
        if: ${{ runner.arch == 'X86' || runner.arch == 'X64' }}
        id: qemu-arm64
        uses: docker/setup-qemu-action@v1
        with:
          image: tonistiigi/binfmt:latest
          platforms: arm64

      - name: Set up QEMU - x86
        if: ${{ runner.arch == 'ARM64'  }}
        id: qemu-x86_64
        uses: docker/setup-qemu-action@v1
        with:
          image: tonistiigi/binfmt:latest
          platforms: x86_64

That's it!
