Is there any way to get Pulumi to render out the YAML manifests for the K8s resources in a stack? Given the repetition and copy/paste etc that would be involved I don't want our engineers to be writing K8s YAML directly, but we've got a subset who understand that fine and want to be able to synth it out so that they can verify that what they've written in Pulumi actually does produce the output they intended in the resulting manifest.

I think it's in beta https://www.pulumi.com/registry/packages/kubernetes/api-docs/provider/#renderyamltodirectory_nodejs

Aah, I was looking for a function somewhere rather than an input. Thank you!

It's been in beta forever. While it hasn't received much attention as far as I know for new features, it works decently well.
