How can I specify an optional field in an external struct using Kubernetes controller-gen?

I am implementing a Kubernetes controller and am creating an API using a struct that looks like:

import (
    corev1 "k8s.io/api/core/v1"
)

type MySpec struct {
    corev1.PodSpec `json:",inline"`
}

However, since the Containers field in PodSpec is required, when generating a corresponding CRD using controller-gen the containers field is being marked as required - however I want it to be optional in my CRD.

Is there any way to override this without copying out the whole structure or patching the output of controller-gen?

For reference the whole project is here.

If your struct should be different, you must declare the fields – Jonas Dec 22 '19 at 19:41
Just curious if you managed to achieve your goals? – Nick Dec 30 '19 at 16:43
@Nick unfortunately not, just patched the output of `controller-gen` in the most transferable way I could think of - was thinking of running it within a Docker container but thought against it – dippynark Dec 30 '19 at 18:32
I also hope to override some filed to be optional or have a default value set. Have you found a solution? Thanks. – zzxwill Sep 20 '20 at 02:28
No I haven't unfortunately – dippynark Sep 22 '20 at 06:11
