<h2>Time Limited Background Operations<aclass="headerlink"href="#time-limited-background-operations"title="Permalink to this headline">¶</a></h2>
<p>Long running operations can be backgrounded, and their status can be
checked on later. The same job ID is given to the same task on all
hosts, so you won’t lose track. Polling support is pending in the
command line.:</p>
<divclass="highlight-python"><pre>ansible all -B 3600 -a "/usr/bin/long_running_operation --do-stuff"
ansible all -n job_status -a jid=123456789</pre>
hosts, so you won’t lose track. If you kick hosts and don’t want
to poll, it looks like this:</p>
<divclass="highlight-python"><pre>ansible all -B 3600 -a "/usr/bin/long_running_operation --do-stuff"</pre>
</div>
<p>If you do decide you want to check on the job status later, you can:</p>
<divclass="highlight-python"><pre>ansible all -n job_status -a jid=123456789</pre>
</div>
<p>Polling is built-in and looks like this:</p>
<divclass="highlight-python"><pre>ansible all -B 3600 -P 60 -a "/usr/bin/long_running_operation --do-stuff"</pre>
</div>
<p>The above example says “run for 60 minutes max (60*60=3600), poll for status every 60 seconds”.
Poll mode is smart so all jobs will be started before polling will begin on any machine.
Be sure to use a high enough <cite>–forks</cite> value if you want to get all of your jobs started
very quickly.</p>
<p>Any module other than <aclass="reference internal"href="modules.html#copy"><em>copy</em></a> or <aclass="reference internal"href="modules.html#template"><em>template</em></a> can be
backgrounded. Typically you’ll be backgrounding shell commands or
software upgrades only.</p>
