<div><br>
</div>
<div>When I was doing a Swift/Keystone only install with DevStack I used the following in my localrc</div>
<div><br>
</div>
<div>
<div> disable_all_services</div>
<div> enable_service key swift mysql</div>
</div>
<div><br>
</div>
<div>Then stack.sh paused with the error message</div>
<div><br>
</div>
<div>
<div> ERROR: at least one rpc backend must be enabled,</div>
<div> set one of 'rabbit', 'qpid', 'zeromq'</div>
<div> via ENABLED_SERVICES.</div>
</div>
<div><br>
</div>
<div>So I blindly added rabbit to enable_service and the error went away. Then I did the PR <a href="https://review.openstack.org/#/c/22333/">https://review.openstack.org/#/c/22333/</a> to change the DevStack README.md file.</div>
<div><br>
</div>
<div>But then I got the question, is rabbit really necessary?</div>
<div><br>
</div>
<div>Does anyone know if a Swift/Keystone only install requires AMQP?</div>
<div><br>
</div>
<div>Thanks,</div>
<div>Everett</div>
