Is there any way to debug how Pulumi decomposes a Helm chart? I'm having an issue where a value I set in the Helm chart doesn't seem to be translated into the actual service Pulumi creates, all the other values work fine, but not this one and I can't see why

Yep, as @better-rainbow-14549 said, you can tell the K8s provider to write the output to a directory instead of submitting to your k8s cluster. That might help troubleshoot it. https://www.pulumi.com/docs/guides/adopting/from_kubernetes/#rendering-kubernetes-yaml

you can also put your values in a

values.yaml

and do

helm template --values values.yaml

that's all pulumi does under the hood

Thanks, that let me find the problem, all sorted now
