. In the *Cluster name* field, enter a name for the cluster.

. In the *Base domain* field, enter a base domain. For example:

All DNS records must be subdomains of this base domain and include the cluster name, for example:

----
<cluster_name>.example.com
----
+
[NOTE]
====
You cannot change the base domain or cluster name after cluster installation.
