You can filter using the **-f** or **--filter** flag. The filtering format is a **key=value** pair. To specify 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=** or **label==**) * **name** (a volume's name) `
