One-line summary

Build MultiArch docker images for ghcr.io and zalando internal repository, mimicking what is done on the skipper repository.

Description

  1. .github/workflows/docker-multiarch.yaml - Complete workflow that:
  • Builds for linux/amd64 and linux/arm64 architectures
  • Replaces alpine as base image for a static image approach
  • Pushes to ghcr.io
  • Includes vulnerability scanning with Trivy
  • Supports multiple triggers (pushes, tags, PRs, manual dispatch)
  • Uses proper authentication with GITHUB_TOKEN

  1. Dockerfile.multiarch - Architecture-aware Dockerfile that copies the correct binary based on target platform

  2. docs/MULTIARCH_BUILD.md - Comprehensive documentation explaining the setup, usage, and troubleshooting

Makefile Updates:

Added new targets for multiarch builds:

  • make build.multiarch - Build binaries for both architectures
  • make build.docker.multiarch - Build multiarch Docker image locally
  • make build.push.multiarch - Build and push multiarch image

Types of Changes

  • New feature (non-breaking change which adds functionality)
