    55  By default, volumes are not removed to prevent important data from being
    56  deleted if there is currently no container using the volume. Use the `--volumes`
    57  flag when running the command to prune volumes as well:
    58  
    59  ```bash
    60  $ docker system prune -a --volumes
    61  
    62  WARNING! This will remove:
    63          - all stopped containers
    64          - all networks not used by at least one container
    65          - all volumes not used by at least one container
    66          - all images without at least one container associated to them
    67          - all build cache

   100  ### Filtering
   101  
   102  The filtering flag (`--filter`) format is of "key=value". If there is more
   103  than one filter, then pass multiple flags (e.g., `--filter "foo=bar" --filter "bif=baz"`)
   104  
   105  The currently supported filters are:
   106  
   107  * until (`<timestamp>`) - only remove containers, images, and networks created before given timestamp
   108  * label (`label=<key>`, `label=<key>=<value>`, `label!=<key>`, or `label!=<key>=<value>`) - only remove containers, images, networks, and volumes with (or without, in case `label!=...` is used) the specified labels.
   109  
   110  The `until` filter can be Unix timestamps, date formatted
   111  timestamps, or Go duration strings (e.g. `10m`, `1h30m`) computed
   112  relative to the daemon machine’s time. Supported formats for date
   113  formatted time stamps include RFC3339Nano, RFC3339, `2006-01-02T15:04:05`,
   114  `2006-01-02T15:04:05.999999999`, `2006-01-02Z07:00`, and `2006-01-02`. The local
   115  timezone on the daemon will be used if you do not provide either a `Z` or a
   116  `+-00:00` timezone offset at the end of the timestamp.  When providing Unix
   117  timestamps enter seconds[.nanoseconds], where seconds is the number of seconds
   118  that have elapsed since January 1, 1970 (midnight UTC/GMT), not counting leap
   119  seconds (aka Unix epoch or Unix time), and the optional .nanoseconds field is a
   120  fraction of a second no more than nine digits long.
   121  
   122  The `label` filter accepts two formats. One is the `label=...` (`label=<key>` or `label=<key>=<value>`),
   123  which removes containers, images, networks, and volumes with the specified labels. The other
   124  format is the `label!=...` (`label!=<key>` or `label!=<key>=<value>`), which removes
   125  containers, images, networks, and volumes without the specified labels.
