## Docker ps
|
||
|
|
|
||
|
|
`docker ps` list containers on your system.
|
||
|
|
A simple `docker ps` will only list all *running* containers, whereas for example a `docker ps -a` will list you all containers (including exited).
|
||
|
|
It will provide you with crucial informations regarding your containers like the `CONTAINER ID`, which is especially useful for accessing your container(s).
|
||
|
|
|
||
|
|
```bash
|
||
|
|
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
|
||
|
|
ee49f9048356 container1 "/bin/bash" 7 weeks ago Up 7 weeks spooky_ghost
|
||
|
|
5999014fd133 container2 "/bin/sh -c 'python3…" 7 weeks ago Up 7 weeks ghastly_cats
