Flannel
A simple layer 3 network fabric designed for Kubernetes that provides each pod with a unique, routable IP address.
What is Flannel?
Flannel is a network fabric for containers, specifically designed for Kubernetes. It creates a layer 3 IPv4 network between multiple nodes in a cluster, enabling containers to communicate across hosts with unique IP addresses, which eliminates port mapping complexities and simplifies container networking.
Kubernetes administrators and operators who need a simple, reliable networking solution for pod communication across cluster nodes, as well as Docker users requiring cross-host container networking without Kubernetes.
Developers choose Flannel for its simplicity, reliability, and minimal focus on core networking without policy enforcement, offering multiple backend mechanisms (like VXLAN and host-gw) and seamless integration with Kubernetes via CNI or Docker via etcd.
