Is this something that Pulumi can internalise? Is Pulumi clever enough to determine which k8s APIs to use based on k8s server version?

Hm, you can get the stack name programmatically, that might be a start: https://www.pulumi.com/docs/intro/concepts/stack/#getting-the-current-stack-programmatically You then have this operator, so if I understand correctly, you might be able to know the k8s version, and alter your deployments accordingly https://www.pulumi.com/docs/guides/continuous-delivery/pulumi-kubernetes-operator/ I suppose you're going to use a feature-flag-like programming model for all that if'ing between API versions...

Thanks for the heads up, I’ll read thorough these.
