I am OK with server_type as well.

+ 1 about server_type.
I also think it is OK.
Thanks

After more thinking, I agree with Hongbin that instance_type might make customer confused with flavor, what about using server_type?
Actually, nova has concept of server group, the "servers" in this group can be vm. pm or container.
Thanks!

Hi Hong Bin,
Thanks for your reply.
I think it is better to discuss the 'platform' Vs instance_type Vs others case first.
Attach: initial patch (about the discussion): https://review.openstack.org/#/c/200401/
My other patches all depend on above patch, if above patch can not reach a meaningful agreement.
My following patches would be blocked by that.
Thanks

Kai,
Sorry for the confusion. To clarify, I was thinking how to name the field you proposed in baymodel [1]. I prefer to drop it and use the existing field ‘flavor’ to map the Heat template.

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

+1 for the idea of using Nova flavor directly.
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:
* platform: vm or baremetal
* os: atomic, coreos, …
* coe: kubernetes, swarm or mesos
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:
* flavor: baremetal, m1.small, m1.medium, …
* os: atomic, coreos, ...
* coe: kubernetes, swarm or mesos
This approach can avoid introducing a new field in baymodel to indicate what Nova flavor already indicates.
Best regards,
Hongbin

Maybe somehow I missed the point, but why not just use raw Nova flavors? They already abstract away irconic vs kvm vs hyperv/etc.
Thanks,

All,
IMO virt_type does not properly describe bare metal deployments. What about using the compute_driver parameter?
compute_driver = None
(StrOpt) Driver to use for controlling virtualization. Options include: libvirt.LibvirtDriver, xenapi.XenAPIDriver, fake.FakeDriver, baremetal.BareMetalDriver, vmwareapi.VMwareVCDriver, hyperv.HyperVDriver

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.

I am going to propose a third option:
3. virt_type
I have concerns about option 1 and 2, because “instance_type” and flavor was used interchangeably before [1]. If we use “instance_type” to indicate “vm” or “baremetal”, it may cause confusions.

Hi Magnum Guys,
I want to raise this question through ML.
In this patch https://review.openstack.org/#/c/200401/
For some old history reason, we use platform to indicate 'vm' or 'baremetal'.
This seems not proper for that, @Adrian proposed nova_instance_type, and someone prefer other names, let me summarize as below:
1. nova_instance_type 2 votes
2. instance_type 2 votes
3. others (1 vote, but not proposed any name)
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).
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.
Please help to vote for that name.
Thanks
Best Wishes,
