Streamline Network Policy Generation in OpenShift with Cilium

Did you know that when someone creates a new OpenShift Project, it is immediately usable but does not include network isolation by default? This design choice simplifies self service for developers, while enterprise environments often need to refine it to meet organizational security and multi-tenancy requirements. In this blog, We will cover how you can set up OpenShift to automatically create a CiliumNetworkPolicy when an OpenShift user creates a Project.

What Is Kubernetes Networking?

Kubernetes networking is the system that allows pods, services, nodes, and external resources to communicate inside a Kubernetes cluster. It provides a flat network structure that gives each pod its own IP address and allows traffic to move across worker nodes without network address translation. This simple networking model supports cloud native applications, microservices, and distributed systems that require reliable network communication. Networking in Kubernetes is built on the Container Network Interface, also known as CNI, which configures pod networking and ensures correct routing and connectivity.
