Requirements for K8GB

For a product that provides a complex function like global load balancing, K8GB doesn't require a lot of infrastructure or resources to provide load balancing to your clusters. The latest release, which, as of this chapter's creation, is 0.11.2 –only has a handful of requirements:

The CoreDNS servers Load Balancer IP address in the main DNS zone using the naming standard gslb-ns-<k8gb-name>-gb.foowidgets.k8s; for example, gslb-ns-us-nyc-gb.foowidgets.k8s and gslb-ns-us-buf-gb.foowidgets.k8s

If you are using K8GB with a service like Route 53, Infoblox, or NS1, the CoreDNS servers will be added to the domain automatically. Since our example is using an on-premises DNS server running on a Windows 2019 server, we need to create the records manually.

An Ingress controller

A K8GB controller deployed in the cluster, which will deploy: The K8GB controller
