// +kubebuilder:pruning:PreserveUnknownFields on array field

Struct definition: // +kubebuilder:pruning:PreserveUnknownFields on array field

type Status struct {
	// +kubebuilder:pruning:PreserveUnknownFields
	Deployed   []unstructured.Unstructured `json:"deployed,omitempty"`
}

Generated: x-kubernetes-preserve-unknown-fields: true under deployed

deployed:
  items:
    type: object
  type: array
  x-kubernetes-preserve-unknown-fields: true

Expect: x-kubernetes-preserve-unknown-fields: true under items

deployed: 
  items:
    type: object
    x-kubernetes-preserve-unknown-fields: true
  type: array

Is there a way to generate x-kubernetes-preserve-unknown-fields: true under items for a array field?

[DirectXMan12]

As of controller-tools v0.2.0, all markers apply to the field itself, not items. The current best way to get it to apply to an item instead is something like this:

// +kubebuilder:pruning:PreserveUnknownFields
type MyItem unstructured.Unstructured

type Status struct {
  Deployed []MyItem
}

All that being said: unstructured.Unstructured should have PreserveUnknownFields on by default, please file a bug about that :-)

[realnumber666]

I defined struct like following ↓

//+kubebuilder:pruning:PreserveUnknownFields
type Resource unstructured.Unstructured

// RoleSpec defines the desired state of Role
type RoleSpec struct {
	// Resources allow to define raw kubernetes object yaml here.
	Resources []Resource `json:"resources,omitempty"`
}

Then I execute make and got a error like that

/bin/controller-gen object:headerFile="hack/boilerplate.go.txt" paths="./..."
blahblah/operator/api/v1:-: name requested for invalid type: interface{}
blahblah/operator/api/v1:-: invalid map value type: interface{}
Error: not all generators ran successfully
run `controller-gen object:headerFile=hack/boilerplate.go.txt paths=./... -w` to see all available markers, or `controller-gen object:headerFile=hack/boilerplate.go.txt paths=./... -h` for usage
make: *** [generate] Error 1

Can't understand what this error is talking about, could you please help me? Thanks a lot!

It is sorted out with the latest version of controller-gen v0.10
