%description
flannel is a virtual network that gives a subnet to each host for use with
container runtimes.

Platforms like Google's Kubernetes assume that each container (pod) has a
unique, routable IP address inside the cluster. The advantage of this model is that it
reduces the complexity of doing port mapping.

This package contains the binary to be included into a container image
