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
TYPE                TOTAL               ACTIVE              SIZE                RECLAIMABLE

* `SHARED SIZE` is the amount of space that an image shares with another one (i.e. their common data)
* `UNIQUE SIZE` is the amount of space that is only used by a given image
* `SIZE` is the virtual size of the image, it is the sum of `SHARED SIZE` and `UNIQUE SIZE`
