Can't Import Two Generated Typescript Class that Belong to the Same "Resource Module"

[blaise-bradley]

What happened?

I’m trying to generate code for the IngressRoute and Middleware CRDs from the Traefik Helm Chart. Based on the usage described in the README, it seems like you can only point crd2pulumi to a single file. My approach has been to generate code for each CRD yml file and then move the generated code into separate directories. If I import just one of the generated classes, my program works as expected. When I import both of the generated classes into the same Pulumi program, the planning step fails with the following error:

    TypeError: Invalid Version:

        at Module._extensions..js (node:internal/modules/cjs/loader:1213:10)

My best guess is that there is some kind of conflict since we are trying to register the "resource module" traefik.containo.us/v1alpha1 twice with the same version number.

Expected Behavior

It's possible to import and use both classes in the same program.

Steps to reproduce

1. Run crd2pulumi against two Traefik CRD files such as ingressroute.yaml and middlewares.yaml.

2. Put the generated code in sibling directories. A screenshot of my directory structure is below:
   

3. Import both classes in the same Pulumi program:

import { IngressRoute as TraefikIngressRoute } from "../pulumi-crd/traefik/ingress-route/traefik/v1alpha1";
import { Middleware as TraefikMiddleware } from "../pulumi-crd/traefik/middlewares/traefik/v1alpha1";

4. Attempt to create an instance of each resource:

  const traefikMiddleware = new TraefikMiddleware(
      "traefik-dashboard-auth",
      {
        apiVersion: "traefik.containo.us/v1alpha1",
        kind: "Middleware",
        metadata: {
          name: "basic-auth",
          namespace: traefikNamespace.metadata.name,
        },
        spec: {
          basicAuth: { secret: traefikDashboardCreds.metadata.name },
        },
      },
      { provider: k8sProvider }
    );
    
  
    new TraefikIngressRoute(
      "traefik-dashboard-route",
      {
        metadata: {
          name: "dashboard",
          namespace: traefikNamespace.metadata.name,
        },
        spec: {
          entryPoints: ["web"],
          routes: [
            {
              match:
                "PathPrefix(`/dashboard`, `/dashboard/`) || PathPrefix(`/api`, `/api/`)",
              kind: "Rule",
              services: [{ name: "api@internal", kind: "TraefikService" }],
              middlewares: [
                {
                  name: traefikMiddleware.metadata.name as Output<string>,
                  namespace: traefikNamespace.metadata.name,
                },
              ],
            },
          ],
        },
      },
      { provider: k8sProvider }
  );

Hi @blaise-bradley. Thanks for raising the issue.

As a work-around, I think you can change one of the generated packages to have a different name. This way Pulumi can distinguish between them and won't error because two modules with the same name and version were registered at the same time.

crd2pulumi wasn't design to generate side-by-side compatible packages. We will consider that for the future.

crd2pulumi allows you to generate a single package from multiple input files. Usage example: crd2pulumi --go file1.yaml file2.yaml.
