Flannel Charm

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

This charm will deploy flannel as a background service, and configure CNI for use with flannel, on any principal charm that implements the kubernetes-cni interface.

This charm is maintained along with the components of Charmed Kubernetes. For full information, please visit the official Charmed Kubernetes docs.
