= Configuring DNS on non-bare-metal agent machines
|
|
|
|
The API Server for the hosted cluster is exposed as a `NodePort` service. A DNS entry must exist for `api.<hosted_cluster_name>.<basedomain>` that points to destination where the API Server can be reached.
|
|
|
|
The DNS entry can be as simple as a record that points to one of the nodes in the managed cluster that is running the hosted control plane. The entry can also point to a load balancer that is deployed to redirect incoming traffic to the ingress pods.
