Cilium Cluster Mesh: The eBPF-Powered Multicluster Solution for Kubernetes
summary
Cilium Cluster Mesh claims a single CNI provides multicluster service discovery, identity, encryption, observability and load balancing using eBPF-powered kernel hooks. Architecture uses a per-node agent + cluster-mesh API server to share endpoints and identities. Demo runs on two Kind clusters with IPv6 and FRR BGP plus MetalLB, showing east‑west load balancing across v1/v2 HelloWorld endpoints works natively while north‑south ingress needs a service‑entry workaround to reach remote endpoints. Requirements include same data‑path mode, reachable nodes, non‑conflicting pod CIDRs and open intercluster ports.
