Helm 3: Chart with dependencies fails to deploy

[moconno]

Problem description

I am deploying a helm chart with dependencies using pulumi helm. Pulumi preview fails with a duplicate urn error. I ran with debug and noticed a service account was being created twice.

• Other:

To verify this was an issue with subcharts, I ran pulumi preview on each chart independently and pulumi preview passed.

Chart dependency:

• name: kong
  version: 1.1.0
  repository: https://charts.konghq.com

I initially thought the problem was related to using a subchart, but that turned out to be a red herring.

The actual problem here is that the kong chart includes the ServiceAccount twice:

1. kong/templates/migrations-pre-upgrade.yaml
2. kong/templates/controller-service-account.yaml

The migrations one includes Helm hooks, which we don't currently support (#555), but you can work around this by removing that resource with a transformation:

const chartName = "kong-chart";
new k8s.helm.v2.Chart(chartName, {
    chart: "kong/kong",
    version: "1.1.0",
    transformations: [
        (obj: any) => {
            if (obj.kind === "ServiceAccount" && obj.metadata.name === `${chartName}-kong`) {
                // Omit this resource (https://github.com/pulumi/pulumi-kubernetes/issues/486#issuecomment-527958122)
                obj.apiVersion = "v1"
                obj.kind = "List"
                obj.items = [];
            }
        }
    ]
});

Closing out this issue now, but let me know if this doesn't solve your problem.

Thanks @lblackstone. I'll give that a try!
