I could be wrong here, but I think `helm lint` just checks that the chart is formed correctly — Go templating and all.

I don't think it validates the Kubernetes resources.

Here's an example:

$ helm create foo

$ cd foo

Then change "apiVersion" in deployment.yaml to "apiVersion: nonsense"

In the linting, I got

$ helm lint ==> Linting . [INFO] Chart.yaml: icon is recommended

1 chart(s) linted, 0 chart(s) failed

$ helm template . | kubeval -

ERR - foo/templates/deployment.yaml: Failed initializing schema https://kubernetesjsonschema.dev/master-standalone/deploymen...: Could not read schema from HTTP, response status is 404 Not Found
