How two Kubernetes cluster can talk with each other?

Kubernetes is an open-source container orchestration platform that automates the management and deployment of applications into clusters of services. Kubernetes can be used to deploy and manage multiple clusters, either on-premise or in the cloud. In certain cases, it may be necessary for the clusters to communicate with each other. Let’s take a closer look at how two Kubernetes clusters can communicate with each other.

The first step is to make sure that both clusters are running the same version of Kubernetes. This ensures that they are compatible and able to communicate with each other.

Next, a secure tunnel should be created between the two clusters. This can be done using a VPN or SSH tunnel. The tunnel will allow communication between the two clusters and ensure that traffic is secure.

Once the tunnel has been established, you need to identify which services will be accessed between the two clusters. This can be done by creating a “service mesh”, which is a network of services that will allow communication between the two clusters.

Finally, you need to configure the service mesh so that traffic can pass between the two clusters. This can be done by setting up routing rules for the services that are accessible, as well as ensuring that authentication and authorization are in place.

Once the service mesh is configured and operational, the two clusters should now be able to communicate with each other in a secure manner. Kubernetes clusters can be used for a variety of purposes and having the capability to connect them in this way can have many benefits.
