{{/*
An API object that manages external access to the services in a cluster, typically HTTP.
Ingress may provide load balancing, SSL termination and name-based virtual hosting.

Ingress exposes HTTP and HTTPS routes from outside the cluster to services within the cluster.
Traffic routing is controlled by rules defined on the Ingress resource.

Pre-requisites:
An Ingress controller to satisfy an Ingress. Only creating an Ingress resource has no effect.
All Ingress controllers should fit the reference specification. In reality, the various Ingress
controllers operate slightly differently.

Note: Make sure you review your Ingress controller's documentation to understand the caveats of choosing it.
