Flannel Insights

What is Flannel?

Flannel is a virtual network that gives a pod/container its own subnet. It's a simple and easy way to configure Kubernetes networking. Flannel provides a flat network, where every pod can reach every other pod directly. It is commonly used to create an overlay network for container orchestration systems like Kubernetes, enabling communication between containers across different hosts.
