Cluster Peering

Connect entire Kubernetes clusters across regions or cloud providers.

Overview

Cluster peering creates a WireGuard bridge between two Kubernetes clusters. All pods in the peered CIDR ranges can communicate as if on the same network.

How It Works

1. Install the Lattice operator on both clusters
2. Create a LatticeNetwork CRD on each cluster
3. The operator establishes a WireGuard tunnel between the two gateways
4. Pod-to-pod traffic routes through the tunnel automatically
