Generating OpenAPI spec (OAS) along with CRD

[SantoshKumar4]

Looking for suggestions.
I am generating Kubernetes CRD (Custom Resource Definition) using kubebuilder. Along with CRD, I also need to document the REST endpoints by creating OpenAPI v3 Spec (OAS) file. Is there a way to get this done using controller-gen? (I see that kubebuilder uses controller-gen to create the CRD) and it was recommended to ask the question in this space). I tried exploring +schemapatch generator but felt like it's there for a different reason.

I also want to add sample Request/Response payload and other OpenAPI details (in <>types.go file) to generate complete OAS file. The reason I want to use types.go file as I will have just one source of truth and I don't need to manually write/edit the OAS file.

Any other way would you recommend if controller-gen is not the right tool for this.

Thanks in advance.

validation might not be the only purpose for OpenAPI Spec. We need the OpenAPI Spec for generating client codes in other languages.
