+# 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
+```bash
+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
+```bash
+# 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
