Networkpolicy
Configure Network Policies and Egress Firewalls for a ROSA Cluster
It’s common to want to restrict network access between namespaces, as well as restricting where traffic can go outside of the cluster. OpenShift achieves this with the Network Policy and Egress Firewall resources.
It’s common to use these methods to restrict network traffic alongside Egress IP and other OpenShift and OVN-Kubernetes resources.
