2. Run:

kube-linter lint  .
Warning: no valid objects found.
/kube-linter lint -v .
Warning: failed to load object from /app/example: rendering failed: error processing renderer "kustomize" (*kustomize.Renderer): error rendering kustomize path /app/example: failed to run kustomize for path "/app/example": failed to run kustomize for path "/app/example": kustomize run failed: trouble configuring builtin HelmChartInflationGenerator with config: `
