Add native ARM64 GitHub Actions runner support by Copilot · Pull Request #1923 · hackmdio/codimd
This PR implements native ARM64 GitHub Actions runners to replace QEMU emulation for better performance and reliability.
Changes Made
🚀 Docker Image Builds (push-image.yml)
- Before: All builds ran on
ubuntu-latestwith QEMU emulation for ARM64 - After: Native builds using appropriate runners:
- AMD64 builds:
ubuntu-latest - ARM64 builds:
ubuntu-24.04-arm64
- AMD64 builds:
- Removed: QEMU setup step (no longer needed for native builds)
- Result: Faster, more reliable ARM64 Docker image builds
🧪 Testing & Validation (build.yml)
- Before: Tests only ran on
ubuntu-latest(AMD64) - After: Matrix testing on both architectures:
ubuntu-latest(AMD64)ubuntu-24.04-arm64(ARM64)
- Result: Comprehensive cross-platform testing ensures code compatibility
Key Benefits
- 🏃♂️ Performance: Native ARM64 execution vs emulated builds
- 🔍 Coverage: Testing on both AMD64 and ARM64 platforms
- 🛠️ Maintenance: Cleaner workflows without QEMU complexity
- 🔮 Future-ready: Uses latest GitHub Actions ARM64 runners
Technical Details
The changes use GitHub's native ARM64 runners (ubuntu-24.04-arm) which provide:
- Better performance than QEMU emulation
- Native ARM64 instruction execution
- More reliable builds for ARM64 Docker images
Impact: Minimal changes (8 additions, 8 deletions) with no breaking changes to existing functionality.
Fixes #1922.
