I'm trying to update the prometheus operator helm chart:

Copy code

pulumi:pulumi:Stack (k8s-infra-dev):
    error: Error: Command failed: helm fetch stable/prometheus-operator --untar --version 6.16.0 --destination /tmp/tmp-333MmxKBHLF631a

Is it expected to need to run

helm repo update

After doing that manually the update nearly succeeded:

Copy code

pulumi:pulumi:Stack (k8s-infra-dev):
    error: update failed
 
  kubernetes:policy:PodSecurityPolicy (monitoring/po-grafana):
    error: Plan apply failed: resource monitoring/po-grafana was not successfully created by the Kubernetes API server : podsecuritypolicies.policy "po-grafana" already exists

Ran again and preview looks like the following:

Copy code

Type                                           Name                   Plan
     pulumi:pulumi:Stack                            k8s-infra-dev
     └─ kubernetes:helm.sh:Chart                    po
 +      ├─ kubernetes:policy:PodSecurityPolicy      monitoring/po-grafana  create
 -      └─ kubernetes:extensions:PodSecurityPolicy  monitoring/po-grafana  delete

Is this a case of the resource api versions changing and not being picked up by Pulumi?

Yeah, Pulumi just interacts with helm on your system, so you have to run

helm repo update

to pull in new chart info.

We aren’t currently auto-aliasing PSPs, so that would explain the error you’re seeing

https://github.com/pulumi/pulumi-kubernetes/issues/828 is tracking getting those added for all resources types

Thanks. Is there a workaround to specify the alias myself?

So for CI/CD, we should always run

helm repo update

outside of Pulumi?

You could specify the alias with a transformation along the lines of https://github.com/pulumi/pulumi-kubernetes/blob/049ce63bcafb65b12a2b89621ac6a399118844db/sdk/nodejs/helm/v2/helm.ts#L43-L60 I think

Copy code

transformations: [
    (obj: any, opts: pulumi.CustomResourceOptions) => {
        if (obj.kind === "PodSecurityPolicy") {
            opts.aliases = [
                { parent: opts.parent, type: "kubernetes:policy/v1beta1:PodSecurityPolicy"},
                { parent: opts.parent, type: "kubernetes:extensions/v1beta1:PodSecurityPolicy"},
            ];
        }
    },
],

would work

I’d run

helm repo update

after it gets installed in your CI pipeline

The transform worked great, thanks again.
