Kubernetes federated services have the ability to manage external DNS entries based on services created across a federated set of Kubernetes clusters. In this lab you will setup a Google DNS managed zone to hold the DNS entries. Kubernetes will support other external DNS providers using a plugin based system on the Federated Controller Manager.
The follow command will create a DNS zone named federation. In a production setup a valid managed zone backed by a registered DNS domain should be used.
