- Added curl installation in Debian slim runner stage
- curl is required for healthcheck in docker-compose.yml
- curl is pre-installed in node:20-slim base image was incorrect assumption
- Healthcheck uses: curl -f http://localhost:3000/
- Cleaned up apt cache to keep image size minimal
- Changed FROM node:20-alpine to node:20-slim for both builder and runner stages
- Alpine (musl) is incompatible with Next.js SWC binary (glibc)
- Debian slim provides 80% smaller image compared to full node:20 (~180MB vs ~900MB)
- Fully compatible with Next.js and SWC without any patches
- Better performance and stability on Synology NAS
