Error: chart requires kubeVersion

[radhupr]

Bug description

I'm using kustomization.yaml as below

helmCharts:
  - name: jupyterhub
    repo: https://hub.jupyter.org/helm-chart/
    version: 4.0.0
    releaseName: jupyterhub
    valuesFile: values.yaml

It gives me Error: chart requires kubeVersion: >=1.28.0-0 which is incompatible with Kubernetes v1.26.0 even though I have the target cluster in version 1.30.0

How to reproduce

Run kustomize build --enable-helm . command against the file mentioned above

Expected behaviour

template files created

Actual behaviour

Error: chart requires kubeVersion: >=1.28.0-0 which is incompatible with Kubernetes v1.26.0

Use --debug flag to render out invalid YAML

What happens if you run helm install (or helm upgrade), without kustomize?

[radhupr]

Helm command works as expected
helm upgrade --cleanup-on-fail --install jupyterhub jupyterhub/jupyterhub --namespace jupyterhub --version=4.0.0 --values values.yaml

Whatever renders the helm charta believes it renders for k8s 1.26, so maybe that needs to be specified or you need to update that software? Kustomize software version or conff seems reasonable to look deeper at to resolve this.

I just did a upgrade of kustomize to v5.6.0 and it still the same. Am I the only one facing this then?

Z2JH just uses standard Helm chart.yaml metadata:
https://github.com/jupyterhub/zero-to-jupyterhub-k8s/blob/4.1.0/jupyterhub/Chart.yaml#L11

If it's not working for you try asking on a Kustomize help forum.

addressed by kubeVersion parameter in kustomization.yaml
