Expanding Horizons: Advanced Deployment Strategies in Multi-Cluster Kubernetes Environments
summary
Three-cluster setup—one hub and two workload clusters—uses Istio for multi-primary, multi-network mesh with east‑west gateways and mTLS, Argo CD for app-of-apps GitOps, Prometheus/ Thanos to federate metrics, and Argo Rollouts to run Canary analysis. Rollouts pull Thanos metrics for automated analysis templates, advance in synchronized steps (demo shows concurrent Canary steps and a final switch after step 7 of 8, traffic shifting from 0→100% to v2 in both clusters), and succeed; Git repos and deploy guides are provided.
