Docker and Docker Compose reference for containerized application deployment and management.

Quick Reference

# Container operations
docker ps                         # List running containers
docker ps -a                      # List all containers
docker logs <container>           # View logs
docker logs -f <container>        # Follow logs
docker exec -it <container> sh    # Shell into container
docker inspect <container>        # Full container details

# Compose operations
docker compose up -d              # Start services (detached)
docker compose down               # Stop and remove
docker compose ps                 # List compose services
docker compose logs -f            # Follow all logs
docker compose pull               # Pull latest images
docker compose restart            # Restart services

# Troubleshooting
docker stats                      # Resource usage
docker network ls                 # List networks
docker network inspect <net>      # Network details
docker volume ls                  # List volumes
docker system df                  # Disk usage
docker system prune               # Clean up unused resources

Validation Checklist

Before deploying containers:

• Services defined with specific image tags (not :latest)
• Port mappings without conflicts
• Volumes for persistent data
• Networks configured appropriately
• Resource limits set (memory, CPU)
• Health checks for critical services
• Restart policy appropriate
• Secrets not in images or compose file
• .env file for environment variables
