Gravitational Wormhole: WireGuard for Kubernetes

Wormhole is a Kubernetes network plugin that combines the simplicity of flannel with encrypted networking from WireGuard. Wormhole is a basic CNI plugin for Kubernetes that uses WireGuard for creating a full mesh encrypted network between each host in the Kubernetes cluster. Adopting WireGuard as an underlying network technology creates exciting opportunities for future development and use cases:

Currently, WireGuard doesn’t exist within the Linux kernel on its own and until it gets mainlined and available in common distributions, WireGuard needs to be installed and compiled on the host manually.
