As the utilization of Kubernetes continues to increase, organizations are discovering the necessity of managing and deploying several clusters in order to support essential capabilities such as geo-redundancy, scalability, and fault isolation for their applications. Submariner enables your applications and services to operate seamlessly across various cloud providers, data centers, and geographical regions. To initiate this process, the Broker must be set up on a singular Kubernetes cluster. It is essential that the API server of this cluster is accessible to all other Kubernetes clusters that are linked through Submariner. This can either be a dedicated cluster or one of the already connected clusters. Once Submariner is installed on a cluster equipped with the appropriate credentials for the Broker, it facilitates the exchange of Cluster and Endpoint objects between clusters through mechanisms such as push, pull, and watching, thereby establishing connections and routes to other clusters. It's crucial that the worker node IP addresses on all connected clusters reside outside of the Pod and Service CIDR ranges. By ensuring these configurations, teams can maximize the benefits of multi-cluster setups.
