    18  ## Description
    19  
    20  Remove all unused containers, networks, images (both dangling and unused),
    21  and optionally, volumes.
    22  
    23  ## Examples
    24  
    25  ```console
    26  $ docker system prune
    27  
    28  WARNING! This will remove:
    29          - all stopped containers
    30          - all networks not used by at least one container
    31          - all dangling images
    32          - unused build cache
    33  Are you sure you want to continue? [y/N] y

    50  
    51  By default, volumes aren't removed to prevent important data from being
    52  deleted if there is currently no container using the volume. Use the `--volumes`
    53  flag when running the command to prune anonymous volumes as well:
    54  
    55  ```console
    56  $ docker system prune -a --volumes
    57  
    58  WARNING! This will remove:
    59          - all stopped containers
    60          - all networks not used by at least one container
    61          - all anonymous volumes not used by at least one container
    62          - all images without at least one container associated to them
    63          - all build cache
    64  Are you sure you want to continue? [y/N] y

    96  ### <a name="filter"></a> Filtering (--filter)
    97  
    98  The filtering flag (`--filter`) format is of "key=value". If there is more
    99  than one filter, then pass multiple flags (e.g., `--filter "foo=bar" --filter "bif=baz"`)
   100  
   101  The currently supported filters are:
   102  
   103  * until (`<timestamp>`) - only remove containers, images, and networks created before given timestamp
   104  * 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.
   105  
   106  The `until` filter can be Unix timestamps, date formatted
   107  timestamps, or Go duration strings (e.g. `10m`, `1h30m`) computed
   108  relative to the daemon machine’s time. Supported formats for date
   109  formatted time stamps include RFC3339Nano, RFC3339, `2006-01-02T15:04:05`,
   110  `2006-01-02T15:04:05.999999999`, `2006-01-02Z07:00`, and `2006-01-02`. The local
   111  timezone on the daemon will be used if you do not provide either a `Z` or a
   112  `+-00:00` timezone offset at the end of the timestamp. When providing Unix
   113  timestamps enter seconds[.nanoseconds], where seconds is the number of seconds
   114  that have elapsed since January 1, 1970 (midnight UTC/GMT), not counting leap
   115  seconds (aka Unix epoch or Unix time), and the optional .nanoseconds field is a
   116  fraction of a second no more than nine digits long.
   117  
   118  The `label` filter accepts two formats. One is the `label=...` (`label=<key>` or `label=<key>=<value>`),
   119  which removes containers, images, networks, and volumes with the specified labels. The other
   120  format is the `label!=...` (`label!=<key>` or `label!=<key>=<value>`), which removes
   121  containers, images, networks, and volumes without the specified labels.
