# Flannel

**Canonical:** https://apis.io/providers/flannel/  
**APIs profiled:** 1

Flannel is a simple overlay network that satisfies the Kubernetes networking requirements. 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 larger preconfigured address space. Flannel does not expose its own HTTP/REST API; it stores network configuration in either the Kubernetes API or etcd directly and is managed via configuration files, kubectl, and Helm.
