Overview ¶
Package clusternet implements a WireGuard-based overlay network for Kubernetes. It relies on controller-manager's IPAM to assign IP ranges to nodes and on Kubernetes' Node objects to distribute the Node IPs and public keys.
It sets up a single WireGuard network interface and routes the entire ClusterCIDR into that network interface, relying on WireGuard's AllowedIPs mechanism to look up the correct peer node to send the traffic to. This means that the routing table doesn't change and doesn't have to be separately managed. When clusternet is started it annotates its WireGuard public key onto its node object. For each node object that's created or updated on the K8s apiserver it checks if a public key annotation is set and if yes a peer with that public key, its InternalIP as endpoint and the CIDR for that node as AllowedIPs is created.
