## Other Reference

The framework for this implementation of the CNI plugin is based on the
[containernetworking sample plugin](https://github.com/containernetworking/plugins/tree/main/plugins/sample)

The details for the deployment & installation of this plugin were pretty much lifted directly from the
[Calico CNI plugin](https://github.com/projectcalico/cni-plugin).
