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

||
|
|
Local Volumes 2 1 36 B 0 B (0%)
|
||
|
|
```
|
||
|
|
|
||
|
|

|
||
|
|
```bash
|
