+ 1 about server_type.

I also think it is OK.


Thanks

I’d be comfortable with server_type.

      Actually, nova has concept of server group, the "servers" in this
      group can be vm. pm or container.

        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.

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

        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
