Docker & DevOps Skill

System Configuration

• Docker 29.2.1 installed
• Docker Compose plugin available
• User 'ren' added to docker group
• AMD GPU (RX 6800 XT) with ROCm support for GPU containers

Common Commands

Docker Basics

docker ps                          # List running containers
docker ps -a                       # List all containers
docker images                      # List images
docker-compose up                  # Start services
docker-compose up -d               # Start in background
docker-compose down                # Stop services
docker-compose build               # Build images
docker logs <container>            # View logs
docker exec -it <container> bash   # Enter container

ROCm GPU Support

# Run with AMD GPU support
docker run --device=/dev/kfd --device=/dev/dri --group-add video -it rocm/rocm-terminal

# Docker Compose with GPU
services:
  app:
    devices:
      - /dev/kfd
      - /dev/dri
    group_add:
      - video
    environment:
      - HSA_OVERRIDE_GFX_VERSION=10.3.0

Best Practices

• Use multi-stage builds for smaller images
• Always specify versions in FROM statements
• Use .dockerignore to exclude unnecessary files
• Mount volumes for persistent data
• Use docker-compose for multi-container apps

Common Issues

• If permission denied: user is in docker group but may need re-login
• GPU not visible: check ROCm installation with rocminfo
• Port conflicts: use docker ps to check used ports
