Networking Operators overview
OpenShift Container Platform supports multiple types of networking Operators. You can manage the cluster networking using these networking Operators.
Cluster Network Operator
The Cluster Network Operator (CNO) deploys and manages the cluster network components in an OpenShift Container Platform cluster. This includes deployment of the Container Network Interface (CNI) default network provider plug-in selected for the cluster during installation. For more information, see Cluster Network Operator in OpenShift Container Platform.
DNS Operator
The DNS Operator deploys and manages CoreDNS to provide a name resolution service to pods. This enables DNS-based Kubernetes Service discovery in OpenShift Container Platform. For more information, see DNS Operator in OpenShift Container Platform.
ingress Operator
When you create your OpenShift Container Platform cluster, pods and services running on the cluster are each allocated IP addresses. The IP addresses are accessible to other pods and services running nearby but are not accessible to external clients. The ingress Operator implements the ingress Controller API and is responsible for enabling external access to OpenShift Container Platform cluster services. For more information, see ingress Operator in OpenShift Container Platform.
