Kubernetes Network policies and traffic

I have two pods running within the same namespace there is no connection between then, however I want pod A to permit ingress & egress communication with pod B, I can not modify any of the objects that already exist, or create a new one. How can I accomplish this?

Short answer: you can not do that without editing or creating new objects.

The recommended and supported way to control traffic flow in Kubernetes are Network Policies . You already have them configured in a cluster, so you must edit them or create a new policy to change a traffic flow. Check also this - Kubernetes Network Policy Recipes .
