Custom hostnames based on DNS

By default, when Cloudbreak provisions cloud provider resources, your cloud provider assigns hostnames for your cluster nodes. Optionally, instead of using default hostnames, you can configure Cloudbreak to use custom hostnames based on DNS. To do that, follow the steps for configuring reverse Domain Name System (DNS) described below.

When the cluster node machines are provisioned, they try to make a reverse DNS lookup (by querying of the DNS to determine the domain name associated with a specific IP address); if the reverse DNS lookup returns a valid value, then that value is set as hostname. This is why reverse DNS setup is required for using custom hostnames.
