Kubernetes 1.9 is now available.
However, Ingress resource is still marked as "beta" in the Kubernetes documentation (see https://kubernetes.io/docs/concepts/services-networking/ingress/ : "The Ingress is a beta resource, not available in any Kubernetes release prior to 1.1").
My questions are:
- Why is the Ingress resource marked as beta? Because some features are missing or because the API may change?
- Is it safe to use Ingress resources in a production Kubernetes cluster (on-premise cluster), especially with the official Nginx IngressControler (https://github.com/kubernetes/ingress-nginx)?
