Load balancing between multiple clusters

Running services in multiple clusters can be configured in multiple ways, usually requiring complex and expensive add-ons such as global load balancers from companies like F5. These are very common in the enterprise, and while many organizations implement clusters using add-ons like F5's Global Service Load Balancers (GSLB), there are projects available that provide similar functionality that are low, or no cost, and native to Kubernetes. These projects do not replace all of the features that the vendor solutions provide, but in many cases, we do not need all of the features from the more expensive solutions – we require only a small subset of the features provided.

A new project that has recently been released is K8GB, a CNCF sandbox project. To learn about the project, browse to the project's main page at https://www.k8gb.io.

Since we are using KinD and a single host for our cluster, this section of the book is meant...
