Docker Build Optimization
도커 이미지 크기 최적화(526MB 에서 346MB 로 약 34% 감소) 및 레이어 효율성 99% 달성
Initial Problems
- Image size: 526MB
- Poor layer caching
- Yarn Berry PnP compatibility issues
- Long build times
Optimization Strategy
- Multi-stage build (base → deps → builder → runner)
- Cache mount for dependencies
- Proper .dockerignore configuration
- Fresh base strategy vs copying node_modules
Results
- Final image: 346MB (34% reduction)
- Layer efficiency: 99%
- Improved build cache hit rate
Key Decisions
- Used Alpine Linux base
- Separated dependency installation from build
- Production-only dependencies in final image
- Leveraged BuildKit features
