Dockerfile

# =============================================================================
# WaveKit Multi-Stage Dockerfile
#
# Architecture: Production-ready SDR stream processing framework with s6-overlay
# Process Management: Full process supervision with auto-restart & dependency handling
# Optimization: BuildKit-compatible, multi-platform (amd64/arm64), layer caching
#
# Deployment modes:
#   - full:   Everything (SDR++, WaveKit API, all decoders) - for single-host setups
#   - core:   Just API + decoders (SDR++ externalized) - for distributed setups  
#   - sdrpp:  Just SDR++ server (IQ/audio provider) - for dedicated SDR host
#
# Usage:
#   docker build -t wavekit:latest -f Dockerfile .
#   docker run --rm -it wavekit:latest
# =============================================================================

# ============================================================================
# Stage: base-deps
# Purpose: Common system dependencies for all build stages
# Size: ~150MB (reduced with only-production install)
