I have a YAML file defining multiple Kubernetes resources of various types (separated with --- according to the YAML spec):

apiVersion: apiextensions.k8s.io/v1
kind: CustomResourceDefinition
metadata:
  # ...
spec:
  # ...
---
apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRole
metadata:
  # ...
rules:
  # ...
---
# etc

Now, I want to parse this list into a slice of client.Object instances, so I can apply some filtering and transforms, and eventually send them to the cluster using

myClient.Patch( # myClient is a client.Client instance
  ctx,
  object,       # object needs to be a client.Object
  client.Apply,
  client.ForceOwnership,
  client.FieldOwner("my.operator.acme.inc"),
)

However, I can't for the life of me figure out how to get from the YAML doc to []client.Object. The following gets me almost there:

results := make([]client.Object, 0)

scheme := runtime.NewScheme()
clientgoscheme.AddToScheme(scheme)
apiextensionsv1beta1.AddToScheme(scheme)
apiextensionsv1.AddToScheme(scheme)

decode := serializer.NewCodecFactory(scheme).UniversalDeserializer().Decode
data, err := ioutil.ReadAll(reader)
if err != nil {
	return nil, err
}
for _, doc := range strings.Split(string(data), "---") {
	object, gvk, err := decode([]byte(doc), nil, nil)
	if err != nil {
		return nil, err
	}

    // object is now a runtime.Object, and gvk is a schema.GroupVersionKind
    // taken together, they have all the information I need to expose a
    // client.Object (I think) but I have no idea how to actually construct a
    // type that implements that interface

    result = append(result, ?????)

}

return result, nil

I am totally open to other parser implementations, of course, but I haven't found anything that gets me any further. But this seems like it must be a solved problem in the Kubernetes world... so how do I do it?
