Deploy on multiple Kubernetes clusters
As highlighted in Kubernetes documentation, a single Kubernetes cluster can run only inside a single zone of a single region. This means workloads will be distributed across multiple nodes of a single Kubernetes cluster running in a single region. When geo-distributed SQL workloads like YugabyteDB need to run on Kubernetes, the preferred approach is to create a single YugabyteDB cluster that spans multiple zones of a single Kubernetes cluster or multiple geo-distributed Kubernetes clusters. This page documents the latter configuration.
Google Kubernetes Engine can be easily configured to support global DNS across multiple Kubernetes clusters. Following instructions highlight how to deploy a 3-region YugabyteDB cluster on 3 Kubernetes clusters, each deployed in a different region. It uses the standard single-zone YugabyteDB Helm Chart to deploy one third of the nodes in the database cluster in each of the 3 clusters.
