Deploy a Cluster across Multiple Kubernetes Clusters by KubeBlocks
KubeBlocks supports managing multiple Kubernetes clusters to provide new options for instance disaster recovery and K8s cluster management. KubeBlocks introduces the control plane and data plane to support cross-K8s management.
In terms of actual physical deployment, the control plane can be deployed in a single availability zone (AZ) for simplicity and flexibility. It can also be deployed in multiple different AZs to provide higher availability guarantees. Alternatively, it can be deployed by reusing a data plane, which offers a lower-cost approach to running the control plane.
Create several K8s clusters and prepare the configuration information for deploying KubeBlocks. This tutorial takes three data plane K8s clusters as an example and their contexts are named as k8s-1, k8s-2, and k8s-3.
Create K8s clusters: one for the control plane and several for data plane. Make sure the API servers of these data plane K8s clusters can be reached from the control plane, which should include both network connectivity and access configuration.
