Unable to import Helm release by specifying import ID

[4ux-nbIx]

What happened?

I'm trying to import an existing Helm release inside a custom resource, by providing import resource ID in helm release options.

Get this error when running pulumi preview:

error: kubernetes:helm.sh/v3:Release resource 'd-weu-helm-test-application-with-ingress-helm-release': property chart value {pulumi-package-test-app} has a problem: non-absolute URLs should be in form of repo_name/path_to_chart, got: pulumi-package-test-app; check the chart name and repository configuration.
error: Preview failed: one or more inputs failed to validate

The chart parameter is set to an absolute URL.

I also tried providing chart name only and specifying repositoryOpts. Same error.

Example

const helmRelease = new Release(
      helmReleaseName,
      {
        name: name,
        chart: chartName,
        version: args.version,
        namespace: args.namespace,
        maxHistory: 10,
        atomic: true,
        valueYamlFiles: args.valueYamlFiles,
        values: args.values,
        skipCrds: true,
        createNamespace: false,
        dependencyUpdate: args.dependencyUpdate,
        timeout: args.timeout,
        // repositoryOpts: repositoryOpts
      },
      {
        parent: parent,
        import: args.importId,
        ignoreChanges: args.importId == undefined ? ["name"] : ["*"]
      }
    );

chart parameter has an absolute URL. This code works well when creating new releases (without import specified).

Thanks for reporting this error, and apologies that you're facing it. I am able to reproduce this error.

Simple repro steps:

1. Install a helm chart, eg. PKO, by running:

helm install --create-namespace -n pulumi-kubernetes-operator pulumi-kubernetes-operator oci://ghcr.io/pulumi/helm-charts/pulumi-kubernetes-operator

2. Import using the import resource option

import * as k8s from "@pulumi/kubernetes";
import * as pulumi from "@pulumi/pulumi";

const myRelease = new k8s.helm.v3.Release("myRelease", {
    chart: "pulumi-kubernetes-operator",
    name: "pulumi-kubernetes-operator",
    namespace: "pulumi-kubernetes-operator",
    replace: false,
    skipCrds: true,
    version: "2.0.0",
}, {
  import: "pulumi-kubernetes-operator/pulumi-kubernetes-operator"
});

3. Observe the error

 error: kubernetes:helm.sh/v3:Release resource 'myRelease': property chart value {pulumi-kubernetes-operator} has a problem: non-absolute URLs should be in form of repo_name/path_to_chart, got: pulumi-kubernetes-operator; check the chart name and repository configuration.
    error: Preview failed: one or more inputs failed to validate

It looks like we need to disable Helm release arg validation if we're trying to import using the import resource option.

As a workaround for now, the CLI import method is working. Please see https://www.pulumi.com/registry/packages/kubernetes/api-docs/helm/v3/release/#import for more details on how to do this.

Hi @rquitales,
Thanks for looking into this. CLI import could work, but it'll be difficult to use it for us. We need to import existing Helm releases into a custom component, so we'll have to deploy an empty custom component, pick up it's URN feed it to the CLI import and etc.

We have a lot of Helm releases to import this way, so having it in the code is the only automated way...

When can we expect the fix to be released?
