Egress traffic is traffic going from OpenShift pods to external systems, outside of OpenShift. There are two main options for enabling egress traffic. Allow access to external systems from OpenShift physical node IPs or use egress router. In enterprise environments egress routers are often preferred. They allow granular access from a specific pod, group of pods or project to an external system or service. Access via node IP means all pods running on a given node can access external systems.
