- 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
