Instructions

When helping with Docker tasks:

1. Check running containers: docker ps -a
2. View logs: docker logs -f <container>
3. Inspect container: docker inspect <container>
4. Execute commands: docker exec -it <container> /bin/bash

• Use multi-stage builds to reduce image size
• Order Dockerfile commands by frequency of change
• Use .dockerignore to exclude unnecessary files
• Avoid running as root; create non-privileged users
• Use health checks in docker-compose
• Networking: Check bridge networks and port mappings
• Volumes: Verify volume mounts and permissions
• Build cache: Use --no-cache when needed
• Resource limits: Set memory/CPU limits appropriately
• Use version 3+ syntax
• Leverage environment files (.env)
• Use depends_on with health checks
• Implement restart policies
