hi all,<br>

Hi!<br>
<br>
<br>
I'm from the Mogan team, we chose the same keyward 'baremetal' when<br>
implementing a OSC plugin [1]. As we think the baremetal command is<br>
representative of a baremetal resource, not a service, so it makes sense<br>
for different projects to share the top level resource name that<br>
OpenStack can provide.<br>
<br>
<br>
We do not "own" the word "baremetal", so nothing prevents you from using it.<br>
However, in my experience:<br>
1. This does confuse users, as they expect "openstack baremetal" to be a<br>
prefix belonging to Ironic.<br>
2. Collisions may happen. We had two collisions with TripleO already, one<br>
resulted in us killing a TripleO command abruptly.<br>
<br>
<br>
Alternatively, I don't mind to change this to 'bm' or something like that for Mogan, but some operators told me that it will confuse users more to have both 'baremetal' and 'bm' in there CLI.<br>
And as I understand, ironic commands are not used frequently, and it's even less if ironic inspector can help to automatically enroll nodes/ports.<br>

I don't share this understanding, depends on a situation. A user of a purely baremetal cloud, or an installer like TripleO, may use the baremetal commands all the time.<span class="gmail-m_-8366010200053910201gmail-"><br>

The commands we have implemented are listed below, seems there's no<br>
collision with Ironic presently, and Ironic doesn't manage such resources.<br>
<br>
* openstack baremetal server <action> <args><br>
* openstack bareemtal flavor <action> <args><br>

Ironic does not have any notion of either of these, so it should be fine.<br></blockquote></span></blockquote><div><br></div></div></div>When using the openstack CLI I'm often in a 'discovery' mode, particularly if I'm interacting with a service that I don't often interact with.

I'm still a bit on a -1 side because of potential users confusion. I wonder<br>
how can we send a message across that prefixes do not designate a specific<br>
project, but are rather just part of a "sentence". I'm specifically worried<br>
about confusing "baremetal server" of Mogan with "baremetal node" of Ironic.<br>
For many people these can be synonyms.<br>
<br>
<br>
We copied nova's server resource concept here, so users may easily to accept the 'baremetal server'. For 'baremetal node', seems only operators/administrators may use such commands, so seems the synonyms is not a big problem as they are for different roles.<br>

It's not obvious from a command name, though. They'll just get 403 when trying to use them.<br>

<br>
So, we'd like to ask if our CLI pattern is allowed before we release the<br>
client.<br>
<br>
Thanks in advance!<br>
