Helm reads wrong Kubeversion: >=1.22.0-0 for v1.23.0 as v1.20.0

Question

How to deploy on K8 via Pulumi using the ArgoCD Helm Chart?

Pulumi up Diagnostics:

  kubernetes:helm.sh/v3:Release (argocd):
    error: failed to create chart from template: chart requires kubeVersion: >=1.22.0-0 which is incompatible with Kubernetes v1.20.0

THE CLUSTER VERSION IS: v1.23.0 verified on AWS. And NOT 1.20.0

ArgoCD install yaml used with CRD2Pulumi: https://raw.githubusercontent.com/argoproj/argo-cd/master/manifests/core-install.yaml

Source:

...

cluster = eks.Cluster("argo-example") # version="1.23"

# Cluster provider
provider = k8s.Provider(
    "eks",
    kubeconfig=cluster.kubeconfig.apply(lambda k: json.dumps(k))
    #kubeconfig=cluster.kubeconfig
)

ns = k8s.core.v1.Namespace(
    'argocd',
    metadata={
        "name": "argocd", 
    },

    opts=pulumi.ResourceOptions( 
        provider=provider
    )
)

argo = k8s.helm.v3.Release(
    "argocd",  
    args=k8s.helm.v3.ReleaseArgs(
        chart="argo-cd",
        namespace=ns.metadata.name,
        repository_opts=k8s.helm.v3.RepositoryOptsArgs(
            repo="https://argoproj.github.io/argo-helm"
        ),
        values={
            "server": {
                "service": {
                    "type": "LoadBalancer",
                }
            }
        },
    ),
    opts=pulumi.ResourceOptions(provider=provider, parent=ns),
)

Any ideas as to fixing this oddity between the version error and the actual cluster version?

I've tried:

Deleting everything and starting over.
Updating to the latest ArgoCD install yaml.

Note, this may just be a misleading error message, the real issue might be that the cluster cannot be reached. See https://github.com/pulumi/pulumi-kubernetes/issues/2374 — cbley, May 09 '23 at 13:12

I could reproduce your issue, though I am not quite sure what causes the mismatch between versions. Better open an issue at pulumi's k8s repository.

Looking at the history of https://github.com/argoproj/argo-helm/blame/main/charts/argo-cd/Chart.yaml, you can see that the kubeversion requirement has been added after 5.9.1. So using that version successfully deploys the helm chart. E.g.

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

const namespaceName = "argo";

const namespace = new k8s.core.v1.Namespace("namespace", {
  metadata: {
    name: namespaceName,
  }
});

const argo = new k8s.helm.v3.Release("argo", {
  repositoryOpts: {
    repo: "https://argoproj.github.io/argo-helm"
  },
  chart: "argo-cd",
  version: "5.9.1",
  namespace: namespace.metadata.name,
})

(Not Recommended) Alternatively, you could also clone the source code of the chart, comment out the kubeVersion requirement in Chart.yaml and install the chart from your local path.

Upgrade helm. I had a similar issue where my k8s was 1.25 but helm complained it was 1.20. Tried everything else, upgrading helm worked.

This fixed it for me. Was at helm 3.6 and kubernets 1.24, upgraded helm to 3.12 and the error was gone. Thanks! – Christopher Gertz May 17 '23 at 07:19

Yes, This is helm issue.

Error:- warning: Skipped ready replica check: not known during preview -- will test after apply error: Error: invocation of kubernetes:helm:template returned an error: failed to generate YAML for specified Helm chart: failed to create chart from template: chart requires kubeVersion: >= 1.22.0-0 which is incompatible with Kubernetes v1.20.0

Solotion :-

Helm reads wrong Kubeversion: >=1.22.0-0 for v1.23.0 as v1.20.0
