<div>Hi Patrick,<br>
<br></div>
During the 7.0 development cycle we made a lot of enhancements to
what environment characteristics can be modified through a plugin.
One item that plugins cannot directly modify is the default Fuel
roles and their metadata. That having been said, there is an
open-ended post_install.sh script you can use for your plugin to
"hack" this value. I know of one project that currently disables
the requirement for controller role in a deployment. This may be
helpful in testing a given standalone role that doesn't depend on a
controller.<br>
<br></div>
Here's a link to the script: <a href="http://paste.openstack.org/show/476821/">http://paste.openstack.org/show/476821/</a><br>
</div>
Note that this doesn't reflect "enabled" status of a plugin. It
will make controller min count 0 for all environments. That won't
break them, but it just removes the restriction.<br>
<br></div>
Best Regards,<br></div>
Matthew Mosesohn<br></div>

<div>I second Patrick's idea. In our case we would like to install
standalone RabbitMQ cluster with Fuel reference architecture to
perform destructive tests on it. Requirement to install controller
is an excessive burden in that case.</div>
