# Docker Build Commands

## Setup buildx builder (one-time setup)

# Create and use the multiplatform builder
docker buildx create --name multiplatform --driver docker-container --use
docker buildx inspect --bootstrap

# Or if builder exists, just switch to it
docker buildx use multiplatform

## Build and push multi-platform image (AMD64 + ARM64)

docker buildx build --platform linux/amd64,linux/arm64 -t ghcr.io/sethwv/ws4kp-to-hls:latest --push .

## Build without pushing (for testing)

docker buildx build --platform linux/amd64,linux/arm64 -t ghcr.io/sethwv/ws4kp-to-hls:latest .

## Build single platform for quick testing (AMD64 only)

docker buildx build --platform linux/amd64 -t ghcr.io/sethwv/ws4kp-to-hls:test --push .

## Notes

- Build includes high-quality audio processing (VBR q6, ~192kbps avg)
- Music files are normalized during build (EBU R128 standard)
- Initial build takes ~90s for music download + processing
- Subsequent builds are faster (Docker layer caching)
