    Docker Multi-Stage Builds

    Node.js (Next.js)

    Prerequisites: set output: 'standalone' in next.config.js. Serve public and .next/static from a CDN, or copy them into the runtime image's public and .next/static directories; standalone output does not include them automatically.

    FROM node:22-alpine AS builder
WORKDIR /app
COPY . .
RUN npm ci && npm run build

FROM node:22-alpine
COPY --from=builder /app/.next/standalone ./
USER 1001
CMD ["node", "server.js"]

    Python (FastAPI) — ~120MB

    Go — ~15MB

    Rust — ~10MB

    All use non-root users and multi-stage for minimal attack surface.
