Deployment and operations

Prompt template:

I need to generate a Dockerfile for a Next.js 16 app with the following requirements:
1. Use a multi-stage build to optimize image size
2. Use a Node.js 18 Alpine image
3. Install pnpm as the package manager
4. Build the production version
5. Run as a non-root user
6. Expose port 3000
7. Optimize build caching

Please generate:
- A complete Dockerfile
- A .dockerignore file
- Build and run instructions

# Dockerfile
# Build stage
FROM node:18-alpine AS builder

WORKDIR /app

# Install pnpm
RUN npm install -g pnpm

# Copy dependency files
COPY package.json pnpm-lock.yaml ./
RUN pnpm install --frozen-lockfile

# Copy source code and build
COPY . .
RUN pnpm build

# Runtime stage
FROM node:18-alpine AS runner

WORKDIR /app

ENV NODE_ENV=production

# Create non-root user
RUN addgroup --system --gid 1001 nodejs
RUN adduser --system --uid 1001 nextjs

# Copy build artifacts
COPY --from=builder --chown=nextjs:nodejs /app/.next ./.next
COPY --from=builder --chown=nextjs:nodejs /app/node_modules ./node_modules
COPY --from=builder --chown=nextjs:nodejs /app/package.json ./
COPY --from=builder --chown=nextjs:nodejs /app/public ./public

USER nextjs

EXPOSE 3000

CMD ["node_modules/.bin/next", "start"]
