Docker Containers
Run, list, stop, and clean up containers in daily work.
Commands
| Command | What it does |
|---|---|
docker ps | List running containers |
docker ps -a | Include stopped containers |
docker run -d --name web -p 8080:80 nginx:1.27 | Start detached with port mapping |
docker stop <name> && docker rm <name> | Stop then remove |
docker container prune | Remove all stopped containers |
Example
docker run -d --name web -p 8080:80 nginx:1.27
docker ps
docker stop web && docker rm webFAQ
Why did my container exit immediately?
The main process ended (e.g. bash without -it). Check docker ps -a plus docker logs to see why.
How do I auto-restart containers?
Add --restart unless-stopped (or an orchestrator); plain docker run never restarts on its own.
