Features: - Enable Docker Buildx with advanced caching - Add BuildKit cache mount for Maven dependencies - Use Aliyun Maven mirror for faster dependency downloads - Optimize Docker layer caching strategy - Add automatic cache cleanup to prevent disk overflow - Increase build timeout to 30 minutes - Add buildx builder instance management Performance improvements: - Parallel builds with Buildx - Persistent Maven cache with RUN --mount=type=cache - Layer-optimized Dockerfile structure - Automatic cache rotation This should significantly reduce Docker build time and improve reliability.
