The `docker system df` command displays information regarding the
|
|
|
|
|
amount of disk space used by the docker daemon.
|
|
|
|
|
|
|
|
|
|
By default the command will just show a summary of the data used:
|
|
|
|
|
```bash
|
|
|
|
|
$ docker system df
|
|
|
|
|

|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
