kubebuilder-helm does not support per resource labels

[tchinmai7]

What broke? What's expected?

kubebuilder-helm ignores per-resource labels and deosn't copy them over to the generated CRDs. For instance, a resource that has a label

// +kubebuilder:object:root=true
// +kubebuilder:subresource:status
// +kubebuilder:metadata:labels=cluster.x-k8s.io/v1beta1=v1beta1

// Foo is the Schema for the foos API
type Foo struct {
        metav1.TypeMeta `json:",inline"`

        // metadata is a standard object metadata
        // +optional
        metav1.ObjectMeta `json:"metadata,omitempty,omitzero"`

        // spec defines the desired state of Foo
        // +required
        Spec FooSpec `json:"spec"`

        // status defines the observed state of Foo
        // +optional
        Status FooStatus `json:"status,omitempty,omitzero"`
}

doesn't get that specific label, and instead only has

apiVersion: apiextensions.k8s.io/v1
kind: CustomResourceDefinition
metadata:
  labels:
    {{- include "chart.labels" . | nindent 4 }}
  annotations:
    {{- if .Values.crd.keep }}
    "helm.sh/resource-policy": keep
    {{- end }}
    controller-gen.kubebuilder.io/version: v0.18.0
  name: foos.example.org

where chart.labels is defined as

{{- define "chart.labels" -}}
{{- if .Chart.AppVersion -}}
app.kubernetes.io/version: {{ .Chart.AppVersion | quote }}
{{- end }}
{{- if .Chart.Version }}
helm.sh/chart: {{ .Chart.Version | quote }}
{{- end }}
app.kubernetes.io/name: {{ include "chart.name" . }}
app.kubernetes.io/instance: {{ .Release.Name }}
app.kubernetes.io/managed-by: {{ .Release.Service }}
{{- end }}

however the CRD that's generated by default in config/crd/bases already has the correct label

apiVersion: apiextensions.k8s.io/v1
kind: CustomResourceDefinition
metadata:
  annotations:
    controller-gen.kubebuilder.io/version: v0.18.0
  labels:
    cluster.x-k8s.io/v1beta1: v1beta1
  name: foos.example.org

Reproducing this issue

Create a kubebuilder project and create an api

kubebuilder init --domain example.org
kubebuilder create api --kind Foo --version v1alpha1 --resource --controller

add a label to the resource

// +kubebuilder:metadata:labels=cluster.x-k8s.io/v1beta1=v1beta1

run make manifests
and generate a helm chart using kubebuilder edit --plugins=helm/v1-alpha
