-*Description*: In Red Hat OpenShift, _Ingress_  is an API object developers can use to expose services through an HTTP(S) aware load balancing and proxy layer through a public DNS entry. The Ingress resource might further specify TLS options and a certificate, or specify a public CNAME that the OpenShift Ingress Controller should also accept for HTTP and HTTPS traffic. An administrator typically configures their Ingress Controller to be visible outside the cluster firewall and might also add additional security, caching, or traffic controls on the service content.

+*Description*: In Red Hat OpenShift, _Ingress_  is a Kubernetes API object that developers can use to expose services within the cluster through an HTTP(S) load balancer and a proxy layer by using a public DNS entry. The `Ingress` resource defines the cluster-wide configuration for ingress traffic, and provides the ability to specify TLS options, a certificate, or a public CNAME that the OpenShift `IngressController` object can accept for HTTP(S) traffic. Additionally, _ingress_ can also be used to describe the incoming direction of network traffic. In Red Hat OpenShift, for example, this traffic is described as entering (ingress) or leaving (egress) an OpenShift cluster.
