# docker
Manage [containers](Containers) (shared kernel, separate userland)

# Monitoring
`docker ps -a`
- list all (stopped) containers

`docker stats`
- live mem, cpu, net/block IO, pids

`docker logs -n 100 --follow CONTAINER`
- `tail -f` for containers

`docker top CONTAINER`
- see procs inside a container

# Cleanup
`docker image prune -a`
- removes images not used by any container
- most of the time all you really need
