TypeMeta : Kind + ApiVersion are empty

[cmoulliard]

Bug

When I create a Component's custom resource, the component is well created and the MetaData well defined (Kind, ApiVersion)

oc get cp/fruit-client -o yaml                
apiVersion: component.k8s.io/v1alpha1
kind: Component
metadata:
  name: fruit-client
  namespace: my-spring-app
spec:
  deployment: innerloop
  exposeService: true
  runtime: springboot
  version: 1.5.16

but when the reconcile's function of the controller fetch the Component, then the Kind, ApiVersion fields are empty

What is the root cause of this issue ?

Environment

okd : 3.11
operator-sdk : v0.1.1+git

Project

Code of the API : https://github.com/snowdrop/component-operator/tree/operator-0.1.1/pkg/apis
Code of the controller : https://github.com/snowdrop/component-operator/blob/operator-0.1.1/pkg/controller/component/handler.go#L94

I have debugged the code and what I can say is that if the Component has already been cached, then we will get it with the fields set but if the obj has not been yet cached (= when it is created the first time), then the fields are empty ....

which operator sdk cli version did you use to generate the project?

[cmoulliard]

generate

As mentioned into my ticket, I used v0.1.1 to regenerate the API of my project.

BTW, I confirm that when the first time the object is retrieved [1] from the cache of the reader, then the fields are empty.

// Get checks the indexer for the object and writes a copy of it if found
func (c *CacheReader) Get(_ context.Context, key client.ObjectKey, out runtime.Object) error {
	storeKey := objectKeyToStoreKey(key)

	// Lookup the object from the indexer cache
	obj, exists, err := c.indexer.GetByKey(storeKey) // TypeMeta/Kind and ApiVersion = ""

Question :

• Do we have an issue during deepCopy process ?
• Should we open a ticket for the kubernetes controller-runtime project ?

cc @hasbro17 You might know more about this.

1. Yes, if this is something that you can not live without then you will need to submit a bug to controller runtime.
2. Can you please explain the use case? Why is it is important to you that these fields are set? I can help get this change upstream if I understand the use case and why you need it.

This is needed by some OpenShift's resources when they are created (DeploymentConfig, Route, ImageStream,....)

Error DeploymentConfig.apps.openshift.io "fruit-client" is invalid: metadata.ownerReferences.kind: Invalid value: "": kind must not be empty is generated here - https://goo.gl/SuzM9p
