[BUG] kube-linter fails but helm template doesn't

[mreiche]

System info:

• OS: MacOSX

Describe the bug

When linting a complete helm chart like:

kube-linter lint -v ./path/to/chart

I get a response like:

failed to render: template: my-chart/templates/template.yaml:1:4
...
at <.Values.global.property>: nil pointer evaluating interface {}.property

But rendering the chart like:

helm template ./path/to/chart

is just fine.

To Reproduce

I did not find a chart public to reproduce. But it must be a Chart, that has a templates Chart dependency.

Expected behavior
kube-linter should be able to render the chart or provides a stdin feature like:

helm template ./path/to/chart | kube-linter lint
