Thanks for opening this, this is a relatively simple change that just needs +optional added to the Group field.

Hi @youngnick
Please assign me this issue. I'd like to fix this.
Thanks

Though it is a simple change, it relaxes the constraints on an api already marked v1. Not sure that is halal with the maintainers? Should this struct be copied for the BackendTLSPolicy and only relaxed there or relaxed everywhere? @youngnick

This is strange. I didn't have any issue with this in my PR for testing BackendTLSPolicy. caCertificateRefs should look something like this.

spec:
  targetRefs:
  - group: ""
    kind: Service
    name: "backendtlspolicy-test"
  validation:
    caCertificateRefs:
    - group: ""
      kind: Secret
      name: "backend-tls-checks-certificate"

I guess there is nothing to fix here. I remember getting error from k8s but I can't reproduce this in k8s 1.31 anymore.

required just means something is set (even if that is empty ""). https://stackoverflow.com/a/45577763/244009

Sorry for the false alert.

there's still a bug here, the doc string says when unspecified or empty , this can imply the field is optional, but rn its required

@arkodg please see here: https://kubernetes.slack.com/archives/CR0H13KGA/p1726101749146929?thread_ts=1725096986.532939&cid=CR0H13KGA

I've reopened because I agree that this field should be optional. Kind and Name still need to be required though.

This is a good-first-issue still, because it's a small, contained change.

Hi @youngnick,

I hope you’re doing well! Could you please assign this task to me? I’d like to take it if it's still up for grabs :)

Hey @youngnick would you be willing to remove this tag and the help-wanted one, if @tamalsaha is working on it, and it's on hold now? #3332 (comment)

I am not working on it. I don't understand what is acceptable to the maintainers. If anyone wants to take over, please feel free to do so.

As per the last comment on #3332 (#3332 (comment)), @robscott suggested that we instead change the doc string to just say "when empty string" instead of "when unspecified or empty string". On reflection, I probably tend to agree.

Let's drop this onto the community meeting agenda for this week and see if there can be some consensus.
