Useful Dockerfile patterns

Python multi-stage (FastAPI)

FROM python:3.12-slim AS base
WORKDIR /app
RUN adduser --disabled-password --gecos '' appuser

FROM base AS deps
COPY pyproject.toml .
RUN pip install --no-cache-dir -e .

FROM base AS production
COPY --from=deps /usr/local/lib/python3.12/site-packages /usr/local/lib/python3.12/site-packages
COPY --from=deps /usr/local/bin /usr/local/bin
COPY src/ src/
USER appuser
CMD ["uvicorn", "src.main:app", "--host", "0.0.0.0", "--port", "8000"]

Node.js standalone (Next.js)

FROM node:22-alpine AS base
FROM base AS deps
WORKDIR /app
COPY package.json pnpm-lock.yaml ./
RUN corepack enable && pnpm install --frozen-lockfile

FROM base AS builder
WORKDIR /app
COPY --from=deps /app/node_modules ./node_modules
COPY . .
RUN pnpm build

FROM base AS runner
WORKDIR /app
ENV NODE_ENV=production
COPY --from=builder /app/.next/standalone ./
COPY --from=builder /app/.next/static ./.next/static
COPY --from=builder /app/public ./public
EXPOSE 3000
CMD ["node", "server.js"]
