@witty-honey-18052 are you using

helm template

? Helm uses the version of Kubernetes that the cluster lists. For

helm template

you can use the

--kube-version

flag to set the version you want.

Hi @famous-caravan-42165, so part of my issue is that i'm trying to use Skaffold to drive the helm deployment. One workaround was to try using the below flags (--validate, to force helm to use the server version), which seems to work for

skaffold render

but breaks the install/upgrade (

skaffold dev

skaffold run

, which fails when validate is not a recognized option for those commands,

Error: unknown flag: --validate

)

Copy code

helm:
    flags:
        global:
          - --validate

I should be able to pass --kube-version in the flags as well, and will give that a try

When Helm communicates to the k8s API it uses the specific version of k8s that’s running. For

helm template

there is no cluster to connect to. So, it uses a default value of the latest.

--kube-version

works there.

That's what I had expected as well as far as helm using the k8s version, but it's been a wild ride trying to find out why it isn't happening in this case. (Or at least why the version error is what is being printed)

This is a similar thread to what I'm experiencing https://kubernetes.slack.com/archives/CABQMSZA6/p1669803652430549

My goal is to provide a skaffold file for bundled Rancher Extension development, which includes modules for cert-manager and Rancher

skaffold uses helm template. see https://skaffold.dev/docs/renderers/helm/#how-helm-render-support-works-in-skaffold

it looks like it isn't supported (yet) to provide flags specifically to helm template from the skaffold yaml

Just to show how silly this seems, this is the error message when attempting to deploy 2.7.2-rc8, without the

--validate

flag

Copy code

Error: chart requires kubeVersion: < 1.26.0-0 which is incompatible with Kubernetes v1.26.0

witty-honey-18052

but I think this is boiling down to being an issue on skaffold's end

Ok I think I resolved this by moving the helm configuration into

deploy

instead of

manifests
