Docker Best Practices

Containerization guidelines for Node.js applications.

Multi-stage Build

# Build stage
FROM node:20-alpine AS builder
WORKDIR /app
COPY package*.json ./
RUN npm ci --only=production
COPY . .

# Production stage
FROM node:20-alpine
WORKDIR /app
COPY --from=builder /app/dist ./dist
COPY --from=builder /app/node_modules ./node_modules
EXPOSE 8080
CMD ["node", "dist/server.js"]

Best Practices

• Use Alpine for smaller images
• Multi-stage builds for separation
• Don't run as root
• Use .dockerignore
• Pin base image versions
• Scan for vulnerabilities
