Problem Description

When using kustomize or helm template to render the chart .Capabilities isn't available. This results in the wrong behavior in the ingress object despite supporting the new API version.

Proposed Solution

Allow for a value that overrides the k8s version coming from the .Capabilities function. Allows for easy support for rendering via helm template or kustomize.
