The label value will not always be cockroachdb. The value needs to be "{{ template \"cockroachdb.fullname\" . }}", similar to the CR name.

Thanks for catching that.
To confirm, do you want the value of the row to be exactly:
crdb.cockroachlabs.com/cluster: cockroachdb: "{{ template \"cockroachdb.fullname\" . }}"
Not the quotations. I ask since I'm not sure how template evaluation works for things in values.yaml (rather than things in templates/) - and I don't see any examples of it in the same values.yaml file.

Yeah that should work, you can test it out once by rendering templates.

I recently discovered that if you do not set a labelSelector, it seems not to match anything - so the spread constraint is not useful: kubernetes/kubernetes#135797 (comment).
