<p><font size="2" face="sans-serif">Hi HongBin,</font><br>
<br>
<font size="2" face="sans-serif">I think flavors introduces more confusion than nova_instance_type or instance_type.</font><br>
<br>
<br>
<font size="2" face="sans-serif">As flavors not have binding with 'vm' or 'baremetal',</font><br>
<br>
<font size="2" face="sans-serif">Let me summary the initial question: </font><br>
<font size="2" face="sans-serif"> We have two kinds of templates for kubernetes now, </font><br>
<font size="2" face="sans-serif">(as templates in heat not flexible like programming language, if else etc. And separate templates are easy to maintain)</font><br>
<font size="2" face="sans-serif">The two kinds of kubernets templates, One for boot VM, another boot Baremetal. 'VM' or Baremetal here is just used for heat template selection.</font><br>
<br>
<br>
<font size="2" face="sans-serif">1> If used flavor, it is nova specific concept: take two as example, </font><br>
<font size="2" face="sans-serif"> m1.small, or m1.middle. </font><br>
<font size="2" face="sans-serif"> m1.small < 'VM' m1.middle < 'VM' </font><br>
<font size="2" face="sans-serif"> Both m1.small and m1.middle can be used in 'VM' environment.</font><br>
<font size="2" face="sans-serif">So we should not use m1.small as a template identification. That's why I think flavor not good to be used.</font><br>
<br>
<br>
<font size="2" face="sans-serif">2> @Adrian, we have --flavor-id field for baymodel now, it would picked up by heat-templates, and boot instances with such flavor.</font><br>
<br>
<br>
<font size="2" face="sans-serif">3> Finally, I think instance_type is better. instance_type can be used as heat templates identification parameter.</font><br>
<br>
<font size="2" face="sans-serif">instance_type = 'vm', it means such templates fit for normal 'VM' heat stack deploy</font><br>
<br>
<font size="2" face="sans-serif">instance_type = 'baremetal', it means such templates fit for ironic baremetal heat stack deploy.</font><br>
<br>
<br>
<br>
<br>
<br>
<font size="2" face="sans-serif">Thanks!</font><br>

<font size="2" color="#1F497D" face="Calibri">+1 for the idea of using Nova flavor directly.</font><br>
<font size="2" color="#1F497D" face="Calibri"> </font><br>
<font size="2" color="#1F497D" face="Calibri">Why we introduced the ¡°platform¡± field to indicate ¡°vm¡± or ¡°baremetel¡± is that magnum need to map a bay to a Heat template (which will be used to provision the bay). Currently, Magnum has three layers of mapping:</font>
<ul style="padding-left: 36pt"><font size="2" color="#1F497D" face="Symbol">¡€ </font><font size="2" color="#1F497D" face="Calibri">platform: vm or baremetal</font><br>
<font size="2" color="#1F497D" face="Symbol">¡€ </font><font size="2" color="#1F497D" face="Calibri">os: atomic, coreos, ¡</font><br>
<font size="2" color="#1F497D" face="Symbol">¡€ </font><font size="2" color="#1F497D" face="Calibri">coe: kubernetes, swarm or mesos</font></ul>
<font size="2" color="#1F497D" face="Calibri"> </font><br>
<font size="2" color="#1F497D" face="Calibri">I think we could just replace ¡°platform¡± with ¡°flavor¡±, if we can populate a list of flovars for VM and another list of flavors for baremetal (We may need an additional list of flavors for container in the future for the nested container use case). Then, the new three layers would be:</font>
<ul style="padding-left: 36pt"><font size="2" color="#1F497D" face="Symbol">¡€ </font><font size="2" color="#1F497D" face="Calibri">flavor: baremetal, m1.small, m1.medium, ¡</font><br>
<font size="2" color="#1F497D" face="Symbol">¡€ </font><font size="2" color="#1F497D" face="Calibri">os: atomic, coreos, ...</font><br>
<font size="2" color="#1F497D" face="Symbol">¡€ </font><font size="2" color="#1F497D" face="Calibri">coe: kubernetes, swarm or mesos</font></ul>
<font size="2" color="#1F497D" face="Calibri"> </font><br>
<font size="2" color="#1F497D" face="Calibri">This approach can avoid introducing a new field in baymodel to indicate what Nova flavor already indicates.</font><br>

<ul style="padding-left: 3pt"><font size="2" face="Calibri">One drawback to virt_type if not seen in the context of the acceptable values, is that it should be set to values like libvirt, xen, ironic, etc. That might actually be good. Instead of using the values 'vm' or 'baremetal', we use the name of the nova virt driver, and interpret those to be vm or baremetal types. So if I set the value to 'xen', I know the nova instance type is a vm, and 'ironic' means a baremetal nova instance. </font><br>

<font size="2" face="Arial">Hi Magnum Guys,</font><font size="3" face="sans-serif"><br>
<br>
</font><font size="2" face="Arial"><br>
I want to raise this question through ML.</font><font size="3" face="sans-serif"><br>
<br>
</font><font size="2" face="Arial"><br>
In this patch </font><a href="https://review.openstack.org/#/c/200401/" target="_blank"><font size="2" color="#0000FF" face="Arial"><u>https://review.openstack.org/#/c/200401/</u></font></a><font size="3" face="sans-serif"><br>
<br>
</font><font size="2" face="Arial"><br>
For some old history reason, we use </font><font size="2" face="Arial"><b>platform </b></font><font size="2" face="Arial">to indicate 'vm' or 'baremetal'.<br>
This seems not proper for that, @Adrian proposed nova_instance_type, and someone prefer other names, let me summarize as below:</font><font size="3" face="sans-serif"><br>
<br>
</font><font size="2" face="Arial"><br>
1. nova_instance_type 2 votes</font><font size="3" face="sans-serif"><br>
</font><font size="2" face="Arial"><br>
2. instance_type 2 votes</font><font size="3" face="sans-serif"><br>
</font><font size="2" face="Arial"><br>
3. others (1 vote, but not proposed any name)</font><font size="3" face="sans-serif"><br>
<br>
</font><font size="2" face="Arial"><br>
Let's try to reach the agreement ASAP. I think count the final votes winner as the proper name is the best solution(considering community diversity).</font><font size="3" face="sans-serif"><br>
<br>
</font><font size="2" face="Arial"><br>
BTW, If you not proposed any better name, just vote to disagree all, I think that vote is not valid and not helpful to solve the issue.</font><font size="3" face="sans-serif"><br>
<br>
</font><font size="2" face="Arial"><br>
Please help to vote for that name. </font><font size="3" face="sans-serif"><br>
<br>
</font><font size="2" face="Arial"><br>
Thanks</font><font size="3" face="sans-serif"><br>
