Issue details

Many CRDs reuse existing kubernetes objects. Eg podSpec and it's properties. It would be great to have some heuristic to reuse existing classes from Pulumi.Kubernetes. This will reduce number of generated code but also allow use same logic for those parts. Right it's not possible because despite they have the same properties they are different types.

Hi @rosieks, do you have some example CRDs and types in mind?

[rosieks]

In my example, I have CRDs for Grafana and OpenBao. I also have a helper method that creates a TolerationArgs object, which I use throughout my code.

However, when I use crd2pulumi to generate classes for these CRDs, it generates a new class called GrafanaSpecDeploymentSpecTemplateSpecTolerationsArgs, which is effectively identical to TolerationArgs.

I would like to avoid generating this additional class and instead instruct the tool to reuse TolerationArgs.

I think it could be something like that:

crd2pulumi --type-map "spec.affinity.toleration=Pulumi.Kubernetes.Types.Inputs.Core.V1.TolerationArgs, Pulumi.Kubernetes"

and you can repeat --type-map multiple times.

or

crd2pulumi --type-map-file ./type-mapping.yaml
