[Golang] AWS LB Controller TargetGroupBinding generates empty struct for TargetGroupBindingSpecServiceRefArgs

[crielly]

Essentially, it seems that when generating types from the AWS LB controller's TargetGroupBinding CRD, at least one struct is missing fields (TargetGroupBindingSpecServiceRefArgs).

Expected behavior

I'd expect it to have a Port field:

              serviceRef:
                description: serviceRef is a reference to a Kubernetes Service and
                  ServicePort.
                properties:
                  name:
                    description: Name is the name of the Service.
                    type: string
                  port:
                    anyOf:
                    - type: integer
                    - type: string
                    description: Port is the port of the ServicePort.
                    x-kubernetes-int-or-string: true
                required:
                - name
                - port
                type: object

Current behavior

no fields at all:

type TargetGroupBindingSpecServiceRefPortArgs struct {
}

Steps to reproduce

1. have AWS LB Controller installed in your Kube cluster
2. kubectl get crd targetgroupbindings.elbv2.k8s.aws -o yaml > tgb-crd.yml
3. crd2pulumi --goPath tgb-crd.yml

Context (Environment)

Go 1.16
WSL2 Ubuntu 20.04

Does this only impact the Go code generation, or does it also impact other languages?

[crielly]

I am not in a position to say as I'm not using any other languages with Pulumi.

Have also struck this with traefik CRDs that follow a similar pattern:

              retry:
                description: Retry holds the retry configuration.
                properties:
                  attempts:
                    type: integer
                  initialInterval:
                    anyOf:
                    - type: integer
                    - type: string
                    x-kubernetes-int-or-string: true
                type: object

results in a struct with no parameters.

The same thing happens for Traefik IngressRoute, services port struct has no fields.
CRD: https://github.com/traefik/traefik-helm-chart/blob/5ee335a0f96179ad2457e2d3289776e1c20184d4/traefik/crds/ingressroute.yaml#L87

[Dadavan]

The same thing happens for prometheuses.monitoring.coreos.com (prometheus-operator). The fields PrometheusSpecResourcesLimitsArgs and PrometheusSpecResourcesRequestsArgs are empty structs.
They follow the same pattern as the above, i.e:

  anyOf:
  - type: integer
  - type: string
  x-kubernetes-int-or-string: true

@lukehoban any progress? I'd love to help if you can point me in the right direction

I had a similar issue generating code for dotnet from a crd containing the following pattern:

  anyOf:
  - type: integer
  - type: string
  x-kubernetes-int-or-string: true

It would seem that crd2pulumi ignores the x-kubernetes-int-or-string property if the oneOf, anyOf or allOf properties exists. From what i can gather (specifically here and here) x-kubernetes-int-or-string should take precedence over oneOf, anyOf and allOf.

I fixed it by moving the code for checking for the existence of x-kubernetes-int-or-string above the other three, which made it work for me. A commit containing what i changed to make it work for me can be found here.
