<p>The timeout for all lifecycle commands is 60 seconds. After that, a timeout will
occur, forcing Watchtower to continue the update loop.</p>
<h4 id="pre-update_timeouts">Pre-update timeouts<a class="headerlink" href="#pre-update_timeouts" title="Permanent link">&para;</a></h4>
<p>For the <code>pre-update</code> lifecycle command, it is possible to override this timeout to
allow the script to finish before forcefully killing it. This is done by adding the
label <code>com.centurylinklabs.watchtower.lifecycle.pre-update-timeout</code> followed by
the timeout expressed in minutes.</p>
<p>If the label value is explicitly set to <code>0</code>, the timeout will be disabled. </p>
