Usage Guide
Docker command cheatsheet: images, containers, networks, volumes, Compose — organized by scenario. Local static page, no network lookup needed. Built for Docker beginners getting started fast, or veterans checking a flag.
1. How to use
- Browse by category (images / containers / networks / volumes / Compose).
- Find the command for your scenario, copy and run.
- Pair with the docker-run-to-compose tool to convert commands into config files.
2. Frequent scenarios
- Free up space: docker system prune -a (careful — deletes unused images).
- View logs: docker logs -f container-name, first step in debugging.
- Enter container: docker exec -it container-name /bin/bash.
3. A common beginner mistake
docker run creates a NEW container every time — it is not "restart". To restart, use docker start. Data loss happens when you skip volume mounts (-v); container deletion wipes internal data. Critical data must mount to host directories or named volumes — the only correct way to persist Docker data.

Migrate docker run commands to docker-compose.yml: five advantages of compose over raw run, a flag-by-flag mapping table (ports, volumes, env, restart, networks), the classic pitfalls (bare -e passthrough, anonymous volumes, --rm semantics), and an online converter that runs locally in your browser.
Container Name Is Already in Use: Resolving the Conflict Error
docker run fails with Conflict. The container name /xxx/ is already in use? An old container with the same name still exists — stopped containers keep their names too. Covers finding the squatter with docker ps -a, rm -f to free it, compose down for project leftovers, --rm for one-shot runs, and restart-policy resurrections.
