+// PowerVSPlatformSpec defines IBMCloud PowerVS specific settings for components
+type PowerVSPlatformSpec struct {
+	// ResourceGroup is the IBMCloud Resource Group in which the cluster resides. If not
+	// specified then default resource group of the account will be used.


// specified then default resource group of the account will be used.

I don't see this default implemented in the controller so I assume is how ibm cloud behaves?
I see this is omitempty but Can we also add the +optional to be more explicit?

we initially thought will do this but this value is required for setting up the CCM, so will make this required.

unless marked as optional (omitempty / //optional) it's required so just need to change that and verify in the CRD generation.

enxebre · 2022-04-11T12:36:10Z

+	// Zone is the availability zone where control plane cloud resources are
+	// created.

there's omitempty here, can we add +optional tag too consistently everywhere is optional?

Again we need this value required as well for CCM code, will make this required.

+	// Subnet is the subnet to use for control plane cloud resources.

+	Subnet *PowerVSResourceReference `json:"subnet,omitempty"`


How can this be optional, what happens if it's not set?
Actually I can't see where this is consumed, is it used anywhere?

you are right, these can't be optional. This is not used anywhere because we are using Subnet from PowerVSNodePoolPlatform for the machines, but we need this in the future to create new nodepool(will submit a follow up PR)

Again, can't be optional.

I brought this up in the past: I wonder if both KubeCloudControllerCreds and NodePoolManagementCreds should belong to the generic spec.

+// on IBMCloud PowerVS platform.
+type PowerVSNodePoolPlatform struct {
+	// ServiceInstanceID is the ServiceInstance to use for control plane cloud resources.

which "control plane cloud resources" does this refer to?

oops, this should be NodePool

+
+	// ProcType (dedicated, shared, capped)
+	// +optional
+	ProcType string `json:"procType,omitempty"`


please add open api enum validation tag

How can this be optional, what happens if it's not set?

we have a web hook in the capibm controller to set some of these value default, rightnow I'm not deploying that part of the deployment(future plan is to add support).

So my next question is how are we dealing with other providers?

I don't think that should make any difference, I see webhooks as an additional UX layer. The API need to be solid even nevertheless. If a ProcType is necessary for the controller to work, then the field must be mark as required not optional (or alternative optional and use openAPI crd defaulting, but I rather do the former to avoid surprising opinions/assumptions for consumers). Then in the CLI we can give it a happy path/convenience value by default if we want to.

sure, I will make enum and default.

let's do this a resource quantity

How can this be optional, what happens if it's not set?

I would love to build api accepts value only in GiB format, I'm afraid that user won't be able to take advantage of resource quantity

again, setting defaults in the capibm webhook

+	// +optional
+	Image *PowerVSResourceReference `json:"image,omitempty"`


How can this be optional, what happens if it's not set?

In hypershift we create IBMPowerVSImage resource to onboard the image from release artefacts, but if user wants to test with a different image which is already onboarded into the service then this field is useful, place we are overriding it here: https://github.com/mkumatag/hypershift/blob/1e9207ea17296fca53960b1d5dd44b37c6b3ba45/hypershift-operator/controllers/nodepool/nodepool_controller.go#L519:L537

none of this needs the "powervs-" prefix since this is the powervs subcommand already.

given IBMCloud.ProviderType is a discriminator union PowerVS definition should live there

type IBMCloudPlatformSpec struct { // ProviderType is a specific supported infrastructure provider within IBM Cloud. ProviderType configv1.IBMCloudProviderType `json:"providerType,omitempty"` PowerVS PowerVSPlatformSpec }

This is just a copy/paste error from ibmcloud, this is not required.

In PowerVS it is called BootImage or just Image

Thanks @mkumatag! this is great work. For the sake of doing reasonable reviews and moving small chunks faster I suggest we split this in multiple PRs:
1 - API
2 - Controllers
3 - CLI
