⚡ Lightning Talk: Achieving Unstoppable Stability: Deploying OceanBase Across Multiple Kubernetes Clusters
Lightningat KubeCon + CloudNativeCon China 2025 · on Tuesday, 2025-06-10· at 15:30· Level 16 | Grand Ballroom I·
summary
OceanBase runs across multiple Kubernetes clusters with a single control plane operator in a master cluster managing remote worker clusters via a KubernetesCluster CR that holds credentials so worker clusters run native pods without CRDs. Data uses Paxos protocol with three OB zones each storing a full replica. Prometheus discovers components. Result is surviving entire cluster or cloud provider failures, safer rolling Kubernetes upgrades, and production‑tested resilience where worker clusters keep serving if the master is restored from backup.
