</pre></div> <h3 id="filtering">Filtering</h3> <p>The filtering flag (<code class="language-plaintext highlighter-rouge">--filter</code>) format is of “key=value”. If there is more than one filter, then pass multiple flags (e.g., <code class="language-plaintext highlighter-rouge">--filter "foo=bar" --filter "bif=baz"</code>)</p> <p>The currently supported filters are:</p> <ul> <li>until (<code class="language-plaintext highlighter-rouge"><timestamp></code>) - only remove containers, images, and networks created before given timestamp</li> <li>label (<code class="language-plaintext highlighter-rouge">label=<key></code>, <code class="language-plaintext highlighter-rouge">label=<key>=<value></code>, <code class="language-plaintext highlighter-rouge">label!=<key></code>, or <code class="language-plaintext highlighter-rouge">label!=<key>=<value></code>) - only remove containers, images, networks, and volumes with (or without, in case <code class="language-plaintext highlighter-rouge">label!=...</code> is used) the specified labels.</li> </ul> <p>The <code class="language-plaintext highlighter-rouge">until</code> filter can be Unix timestamps, date formatted timestamps, or Go duration strings (e.g. <code class="language-plaintext highlighter-rouge">10m</code>, <code class="language-plaintext highlighter-rouge">1h30m</code>) computed relative to the daemon machine’s time. Supported formats for date formatted time stamps include RFC3339Nano, RFC3339, <code class="language-plaintext highlighter-rouge">2006-01-02T15:04:05</code>, <code class="language-plaintext highlighter-rouge">2006-01-02T15:04:05.999999999</code>, <code class="language-plaintext highlighter-rouge">2006-01-02Z07:00</code>, and <code class="language-plaintext highlighter-rouge">2006-01-02</code>. The local timezone on the daemon will be used if you do not provide either a <code class="language-plaintext highlighter-rouge">Z</code> or a <code class="language-plaintext highlighter-rouge">+-00:00</code> timezone offset at the end of the timestamp. When providing Unix timestamps enter seconds[.nanoseconds], where seconds is the number of seconds that have elapsed since January 1, 1970 (midnight UTC/GMT), not counting leap seconds (aka Unix epoch or Unix time), and the optional .nanoseconds field is a fraction of a second no more than nine digits long.</p> <p>The <code class="language-plaintext highlighter-rouge">label</code> filter accepts two formats. One is the <code class="language-plaintext highlighter-rouge">label=...</code> (<code class="language-plaintext highlighter-rouge">label=<key></code> or <code class="language-plaintext highlighter-rouge">label=<key>=<value></code>), which removes containers, images, networks, and volumes with the specified labels. The other format is the <code class="language-plaintext highlighter-rouge">label!=...</code> (<code class="language-plaintext highlighter-rouge">label!=<key></code> or <code class="language-plaintext highlighter-rouge">label!=<key>=<value></code>), which removes containers, images, networks, and volumes without the specified labels.</p> <h2 id="parent-command">Parent command</h2> <table> <thead> <tr> <th style="text-align: left">Command</th> <th style="text-align: left">Description</th> </tr> </thead> <tbody> <tr> <td style="text-align: left"><a href="../system/index">docker system</a></td> <td style="text-align: left">Manage Docker</td> </tr> </tbody> </table> <h2 id="related-commands">Related commands</h2> <table> <thead> <tr> <td>Command</td> <td>Description</td> </tr> </thead> <tbody> <tr> <td><a href="../system_df/index">docker system df</a></td> <td>Show docker disk usage</td> </tr> <tr> <td><a href="../system_events/index">docker system events</a></td> <td>Get real time events from the server</td> </tr> <tr> <td><a href="../system_info/index">docker system info</a></td> <td>Display system-wide information</td> </tr> <tr> <td><a href="index">docker system prune</a></td> <td>Remove unused data</td> </tr> </tbody> </table> <div class="_attribution">
