Dockerfile Best Practices
Multi-Stage Build
# Build stage
FROM node:20-alpine AS builder
WORKDIR /app
COPY package*.json ./
RUN npm ci --only=production
COPY . .
RUN npm run build
# Production stage
FROM node:20-alpine AS production
WORKDIR /app
RUN addgroup -g 1001 -S nodejs && \
adduser -S nodejs -u 1001
COPY --from=builder --chown=nodejs:nodejs /app/dist ./dist
COPY --from=builder --chown=nodejs:nodejs /app/node_modules ./node_modules
USER nodejs
EXPOSE 3000
CMD ["node", "dist/index.js"]Layer Optimization
FROM python:3.12-slim
# Install dependencies first (cached unless requirements change)
COPY requirements.txt .
RUN pip install --no-cache-dir -r requirements.txt
# Copy application code (changes frequently)
COPY . .
CMD ["python", "app.py"]Security Hardening
FROM node:20-alpine
# Create non-root user
RUN addgroup -g 1001 appgroup && \
adduser -u 1001 -G appgroup -D appuser
WORKDIR /app
# Copy with proper ownership
COPY --chown=appuser:appgroup . .
# Drop privileges
USER appuser
# Use exec form for proper signal handling
CMD ["node", "server.js"]Building Images
Basic Build
# Build with tag
docker build -t myapp:1.0 .
# Build with build args
docker build --build-arg NODE_ENV=production -t myapp:prod .
# Build for specific platform
docker build --platform linux/amd64 -t myapp:amd64 .
# Build with no cache
docker build --no-cache -t myapp:fresh .Multi-Platform Builds
# Create builder
docker buildx create --name multiplatform --use
# Build for multiple architectures
docker buildx build \
--platform linux/amd64,linux/arm64 \
-t myregistry/myapp:latest \
--push .Running Containers
Basic Operations
# Run container
docker run -d --name myapp -p 8080:3000 myapp:latest
# Run with environment variables
docker run -d \
-e DATABASE_URL=postgres://localhost/db \
-e NODE_ENV=production \
myapp:latest
# Run with resource limits
docker run -d \
--memory="512m" \
--cpus="1.0" \
myapp:latest
# Run with restart policy
docker run -d --restart=unless-stopped myapp:latestVolume Management
# Named volume
docker volume create mydata
docker run -v mydata:/app/data myapp:latest
# Bind mount
docker run -v $(pwd)/config:/app/config:ro myapp:latest
# tmpfs mount (memory)
docker run --tmpfs /tmp:rw,noexec,nosuid myapp:latestNetworking
# Create network
docker network create mynetwork
# Run on network
docker run -d --network mynetwork --name api myapp:latest
# Connect existing container
docker network connect mynetwork existing-container
# Expose specific ports
docker run -d -p 127.0.0.1:8080:3000 myapp:latestContainer Lifecycle
Management Commands
# List containers
docker ps -a
# Stop container
docker stop myapp
# Remove container
docker rm myapp
# Force remove running container
docker rm -f myapp
# Prune stopped containers
docker container prune -fLogs and Monitoring
# View logs
docker logs myapp
# Follow logs
docker logs -f --tail 100 myapp
# View resource usage
docker stats myapp
# Inspect container
docker inspect myappDebugging Containers
Interactive Access
# Execute command in running container
docker exec -it myapp /bin/sh
# Run container with shell
docker run -it --rm myapp:latest /bin/sh
# Debug failed container
docker run -it --entrypoint /bin/sh myap🎯 Best For
