As Kubernetes environments grow, managing multicluster connectivity by hand quickly becomes difficult. Linkerd’s multicluster features now allow teams to handle cross-cluster communication securely and transparently — and with recent improvements, everything can be managed declaratively with GitOps.

In this talk, we’ll explore how Linkerd’s multicluster capabilities have evolved, from early pod-to-pod communication to federated services and full GitOps compatibility. You'll see how platform teams can automate Linkerd multicluster resources like Links and ServiceExports using GitOps tools such as Argo CD or Flux. We'll cover simple patterns that make it easier to connect clusters across clouds and regions while keeping operations secure, repeatable, and reliable.

Key Takeaways:
How Linkerd enables GitOps-style multicluster communication
Managing Linkerd multicluster resources declaratively
Patterns for scaling service mesh across multiple Kubernetes clusters
Lessons from real-world GitOps multicluster deployments
