All of these K8s settings use the K8s API definitions, so [K8s documentation](https://kubernetes.io/docs/concepts/) can
be used for reference. All K8s overlay values are also validated in the operator.

Warning: the helm charts here default to using port 80 and 443, while the old charts used 8080 and 8443.
If you have AuthorizationPolicies that reference port these ports, you should update them during this process,
or customize the ports to match the old defaults.
