+Lists all the volumes Docker knows about. You can filter using the **-f** or

+more than one filter,  pass multiple flags (for example,
+**--filter "foo=bar" --filter "bif=baz"**)
+
+The currently supported filters are:
+
+* **dangling** (boolean - **true** or **false**, **1** or **0**)
+* **driver** (a volume driver's name)
+* **label** (**label=<key>** or **label=<key>=<value>**)
+* **name** (a volume's name)
