Currently controller-tools does not generate any properties for metadata fields at any level in CRD yamls to accommodate for structural schema.

https://github.com/kubernetes-sigs/controller-tools/blob/master/pkg/crd/known_types.go#L29-L33

My it is my understanding that only top level metadata field is restricted to define name & generatedName fields. Any other nested metadata field can have detailed schema. Some common cases are embedding PodTemplate, PersistentVolumeClaim in CRDs.

Currently we are creating our own ObjectMeta types are using them in our CRDs to work around this issue.

Do you think controller-tools could just strip the properties for top level metadata field? One way to do that will be to remove ObjectMeta from known types and then clean the generated yaml before writing to disk.

Any thoughts?

I would prefer to see a stripped down EmbeddedObjectMeta if possible, or at least let controller-gen do the restriction. ObjectMeta has so many fields which do not make sense for embedded ObjectMeta. Also the schema is super huge.

I like the idea of EmbeddedObjectMeta. We kind of doing that in our custom type. https://github.com/kmodules/offshoot-api/blob/master/api/v1/pvc.go#L24-L98

I think #395 is actually close to being mergable, it's just a bit out of date. If someone wants to pick that up, I've left comments on it.

@DirectXMan12 see my comment in 395. IMO we should not do that. Instead let's add a sensible EmbeddedObjectMeta to API machinery and make controller-tools warn if that is not used instead of ObjectMeta.

@sttts that doesn't work for when you embed things with ObjectMeta in them already though -- e.g. PodTemplateSpec, which is probably the most common case. We'd have to swap that out on demand or something.

True. So we must add special handling for embedded ObjectMeta to only specifiy sensible fields (more than just type: object but considerably less than a full ObjectMeta. It's ugly. As written in the other issue: sin of the past :-/

For posterity: if you're developing a CRD with a spec field that uses corev1.PodTemplate, add the generateEmbeddedObjectMeta=true option to your makefile as shown here: openshift/boilerplate#291

This will ensure that your CRD has a schema for ObjectMeta, so that your users may apply labels/annotations to the pod.
