Pro Tips

Use '--cache-from' and '--cache-to' with registry caches to speed up CI/CD builds significantly.

Build for multiple platforms with: 'docker buildx build --platform linux/amd64,linux/arm64 --push .'

Use 'docker buildx create --use' to create a builder with multi-platform support enabled.

Common Mistakes

Multi-platform builds are slower as they may use emulation. Build natively when possible for speed.

Some packages aren't available for all architectures. Test on each target platform.
