# Docker Manage Docker containers, images, networks, and volumes. ## List containers ```bash docker ps --format "table {{.Names}}\t{{.Image}}\t{{.Status}}\t{{.Ports}}" ``` ```bash docker ps -a --format "table {{.Names}}\t{{.Status}}\t{{.Image}}" | head -20 ``` ## Container logs ```bash docker logs my-container --tail 50 ``` ```bash docker logs my-container --since 1h --follow & ``` ## Start / stop / restart ```bash docker start my-container ``` ```bash docker stop my-container ``` ```bash docker restart my-container ``` ## Run a container ```bash docker run -d --name my-app -p 8080:80 nginx:latest ``` ## Execute command in container ```bash docker exec my-container ls -la /app ``` ```bash docker exec -it my-container sh ``` ## Inspect container ```bash docker inspect my-container | jq '.[0] | {State, NetworkSettings: .NetworkSettings.Networks}' ``` ## List images ```bash docker images --format "table {{.Repository}}\t{{.Tag}}\t{{.Size}}\t{{.CreatedSince}}" | head -20 ``` ## Build image ```bash docker build -t my-app:latest . ``` ## Remove container / image ```bash docker rm my-container ``` ```bash docker rmi my-app:latest ``` ## Docker Compose ```bash docker compose ps ``` ```bash docker compose up -d ``` ```bash docker compose logs --tail 50 ``` ## System info ```bash docker system df ``` ```bash docker system prune --dry-run ``` ## Networks ```bash docker network ls ``` ## Volumes ```bash docker volume ls ``` ## Notes - Docker socket must be mounted for the agent to access the host Docker daemon. - Use `--format` with Go templates for structured output. - Always confirm before removing containers, images, or running `prune`. - Use `docker compose` (v2) instead of `docker-compose` (v1).
