Hello, I am getting started with Pulumi. How to deal with Kubernetes Deployment which I already have in yaml file or if I would like to do this: kubectl apply -f https://raw.githubusercontent.com/reactive-tech/kubegres/v1.16/kubegres.yaml ? thank you

I'd use https://github.com/pulumi/crd2pulumi to generate pulumi bindings from the CRDs and https://github.com/pulumi/kube2pulumi to generate a pulumi program. (not sure however if kube2pulumi can use bindings generated by crd2pulumi)

Maybe this also helps? https://www.pulumi.com/docs/guides/adopting/from_kubernetes/
