Flannel is a simple and easy way to configure a layer 3 network fabric designed for Kubernetes. It runs a small, single binary agent called flanneld on each host, and is responsible for allocating a subnet lease to each host out of a large, preconfigured address space. Packets are forwarded using one of several backend mechanisms such as VXLAN and various cloud integrations.
