# Interactive shell (commandline)

Sometimes it's difficult to understand problems within a docker. Like network issues or configurations that need to be adjusted.  
It's quite easy to log into a docker via command line.

1\) open a command line (it can be that you need to activate SSH access) on the hosting system

2\) find the docker image you're interested in

```
docker ps
```

3\) open a shell to the docker using the id from the previous query

```
docker exec -it c05876343 /bin/bash
```

Now you should be inside the docker. To leave the session just type

```
exit
```
