Hi Eli,

This is exactly what I want. If you guys think this requirement is reasonable, I’d like to commit a design spec so that we could discuss it in details.

I think Duan Li is talking about using both 2 kinds of (secure-booted and non-secure-booted) node deploy *minion* node.

The scenario may like this:
let say 2 flavors:

  *   flavor_secure
  *   flavor_none_secure
For now, flavor-id in baymodel can only be set as one value, Duan Li's requirement is to using flavor-id = [flavor_none_secure, flavor_secure]
and provision one cluster which minion nodes are build from 2 types of flavor, then after cluster(bay ) provision finished , passing lable to
let k8s cluster to chose a minion node to start pod on that specific node.

For now, Magnum doesn't support it yet, I think it good to have it, but the implementation may be differnece per COE since after we
provision bay, the scheduler work are done by k8s/swarm/mesos.

Hi Duan Li,

Not sure if I get your point very clearly.

1> Magnum did support :

flavor-id for minion node
master-flavor-id for master node

So your K8s cluster could have such two kinds of flavors.

2> For one question about ironic case (I found you deploy on ironic), I did not think Magnum templates now support ironic case now.
As ironic VLAN related feature are still developing, and not merged(many patches are under review, pick one for example https://review.openstack.org/#/c/277853)

I am not sure how would you use ironic for k8s cluster ?
