<p>Hi Duan Li,<br>
<br>
Not sure if I get your point very clearly.<br>
<br>
1> Magnum did support :<br>
<a href="https://github.com/openstack/magnum/blob/master/magnum/api/controllers/v1/baymodel.py#L65">https://github.com/openstack/magnum/blob/master/magnum/api/controllers/v1/baymodel.py#L65</a><br>
<br>
flavor-id for minion node<br>
master-flavor-id for master node<br>
<br>
So your K8s cluster could have such two kinds of flavors.<br>
<br>
<br>
2> For one question about ironic case (I found you deploy on ironic), I did not think Magnum templates now support ironic case now.<br>
As ironic VLAN related feature are still developing, and not merged(many patches are under review, pick one for example
<a href="https://review.openstack.org/#/c/277853">https://review.openstack.org/#/c/277853</a>)<br>
<br>
<br>
I am not sure how would you use ironic for k8s cluster ? <br>
<br>
Also in this summit <a href="https://etherpad.openstack.org/p/magnum-newton-design-summit-topics">
https://etherpad.openstack.org/p/magnum-newton-design-summit-topics</a>, we will have session about ironic cases:<br>
here it is : <b><span style="font-size:13.5pt">Ironic Integration: Add support for Ironic virt-driver</span></b><br>
<br>
If you had ways to make ironic work with Magnum, we welcome your contribution for that topic.
<br>
<br>
<br>
Thanks<br>
<br>
Best Wishes,<br>
