How to create a federated multi-cluster Kubernetes environment. Step 2. All nodes in a single-zone or multi-zone cluster are controlled by the same cluster master. The regional subnet for load balancers is public, but you specify whether the regional subnets for the Kubernetes API endpoint and for worker nodes are public or private. Kind ( K ubernetes in D ocker) is a tool for running local Kubernetes clusters using Docker containers. If you have multiple Kubernetes (K8s) clusters in different regions and need to run the same application across all of them, it is reasonable to use the so-called Kubernetes … When you deploy multiple AKS clusters, choose regions where AKS is available.
