Subclass Kubevirt InfraManager to separate Openshift Virtualization provider #264

nasark · 2024-08-07T20:17:11Z

We can subclass Kubevirt::InfraManager to create a separate provider for Openshift Virtualization

Depends on:

Add OpenShift Virtualization vendor types for VMs and hosts manageiq#23165
Openshift Virtualization subclassing changes manageiq-providers-kubevirt#247
Separate OSV and Kubevirt virtualization options from form manageiq-providers-kubernetes#537

@agrare WIP - need to test with an Openshift Virtualization provider and clean up specs. Feel free to review what is here though

Does it makes sense for this to just live in the base class, or is this intentionally overriding the class name?

This is here because we have to override the class_name to be Openshift::InfraManager so the correct class gets created

I think this has to be different than the container manager, so maybe something like openshift_virt or openshift_infra?

👍 openshift_infra would be good (OpenStack undercloud/InfraManager is openstack_infra)

I'm surprised so much of this overriding is necessary. Makes me wonder if there's a better way, such as providing a method like manageiq_class, which returns ManageIQ::Providers::Openshift::InfraManager, and then the actual logic would be something like

@manager ||= manager_class.find(@cfg[:ems_id])

This is the simple example of course - the same comment really applies to all of the methods in this file.

Fryguy · 2024-08-07T21:36:09Z

Very cool! I like that we didn't need a new repository, and it's just included in the openshift repo.

Fryguy · 2024-08-07T21:36:59Z

One other thing I think we need is the form for adding a provider needs to change so you can only select OpenShift Virtualization under the Virtualization tab.

This should be ManageIQ::Providers::Openshift::ContainerManager, then you can add an invere_of :infra_manager

+  def authentication_for_providers
+    authentications.where(:authtype => :openshift)


Not necessarily for this PR but if most of these overrides are for :authtype => :openshift we could use e.g. a DEFAULT_AUTH_TYPE constant and switch to that in the base Kubevirt class

e.g.

def connect(opts = {}) # Get the authentication token: token = opts[:token] || authentication_token(:kubevirt)

If we changed that to authentication_token(default_authentication_type)

+  #
+  def connect(opts = {})
+    # Get the authentication token:
+    token = opts[:token] || authentication_token(:openshift)


This is a good example, this whole method is probably copy&paste except for this :openshift here

Is this different from the base class?

agrare · 2024-08-07T22:56:17Z

Not sure if you want to do this in another PR but we should make the "virtualization" endpoint dropdown option (https://github.com/ManageIQ/manageiq-providers-kubernetes/blob/master/app/models/manageiq/providers/kubernetes/container_manager.rb#L331-L342) in the Openshift::ContainerManager subclass only show "Openshift Virtualization"

agrare · 2024-08-08T13:49:02Z

I think we should get some VCR specs in here, kubevirt has some weird mocking that they do for their refresher specs I'm not sure I want to copy what they do but a "simple" refresher spec doing a full refresh should be sufficient.

We don't need to inherit anything from the Kubevirt RefreshWorker, and doing this nests the settings under kubevirt so we typically don't do this for simple workers (e.g. see Openshift::ContainerManager::RefreshWorker it doesn't < Kubernetes)

Should this live in manageiq-decorators? I prefer it in the plugin class, but wasn't sure if it was required over there.

On that note, in manageiq-decorators we use symlinks when there are multiple images that point to the same thing, so this could just be a symlink over there.

It doesn't seem like it's required in manageiq-decorators

Really minor for a follow-up but something this simple taking up 5 lines could be a ternary operator instead on one line

This looks a little out of place, something like "Performs a full refresh" would probably be better.

On that note, a targeted refresh spec would be a good addition in the future

Looks good some minor things that can be follow-ups
