So I deleted resources from my Pulumi's

index.ts

one-by-one by commenting them out and running

pulumi up

. Then after the resource was removed I'd re-attempt to run

pulumi destroy --exclude-protected

to see if the

grpc: the client connection is closing

issue had gone. I found that once I'd deleted all the Helm release resources, and finally commented out the

kubernetes.Provider

created from the

kubeconfig

obtained from the DigitalOcean cluster resource.

export const kubeconfig = doCluster.kubeConfigs[0].rawConfig;
// v HI IT'S ME
const provider = new kubernetes.Provider("k8s-provider", {
  kubeconfig,
});
// ^ I'M THE PROBLEM IT'S ME!
const ingressNginxNamespace = new kubernetes.core.v1.Namespace(
  "ingress-nginx-namespace",
  {
    metadata: {
      name: "ingress-nginx",
    },
  },
  {
    provider,
  }
);

The issue finally went away.

Do you want to perform this destroy? details

Any ideas why the kubernetes provider is causing this issue when performing a destroy.
