## Docker exec
|
||
|
|
|
||
|
|
`docker exec` allows you to run a command in a running container.
|
||
|
|
By command, any available command (inside of container) is meant,
|
||
|
|
allowing you to start/stop/execute any kind of routine and even some complex actions.
|
||
|
|
Also combined with args `-it` and `bash|sh|csh|zsh` (depending on container) allows you to enter a container, just like ssh-ing it.
|
||
|
|
(It'll throw you into your `WORKDIR`)
|
||
|
|
|
||
|
|
Example:
|
||
|
|
```bash
|
||
|
|
docker exec -it ee49f9048356 bash
|
||
|
|
root@ee49f9048356 \ $
|
||
|
|
```
