Subject: [PATCH] [stable/nginx-ingress] Add substitution for containerPorts
 from values (#17037)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* [stable/nginx-ingress] Add substitution for containerPorts from values

Use key-value range from .Values.controller.containerPort definition instead of mapping 1to1 http and https ports.

It allows passing extra configuration to nginx-ingress, such as validation-webhook with its own port, and define this port in values.
Without this option it’s not possible because of hardcoded http and https ports in deployment/daemonset templates.

Does not break anything.

* [stable/nginx-ingress] Bump version to 1.20.0
