What are the steps to use Custom Hostname for Cloudbreak created cluster using CLI?

SupportKB

Problem Description:

When using Cloudbreak (2.7) to launch HDP cluster, by default it takes hostname as ip-XX-XXX-XX-XX. What are the steps to use custom hostname through CLI? 

Cause:

Solution:
To setup custom hostnames, perform either of the following: 

• Follow the steps mentioned in documentation at Using custom hostnames based on DNS. 
• Or, implement custom domain and custom hostname in a blueprint and deploy the cluster through the Cloudbreak CLI. 

Add the following block in the CLI cluster JSON template as top level item to define the custom hostname: 

"customDomain": { 
"customDomain": "hortonworks.com", 
"customHostname": "test" 
},

The VM names will be like test0, test1, test2.. test3.hortonworks.com.

To determine where this customDomain setting needs to be added in the template file, obtain the cluster template JSON file at the end of the cluster creation steps by clicking on the Show CLI Command button at the bottom of the screen. 

The cluster needs to be installed through CLI with example command with a cluster template JSON file as input file, which has the customDomain setting added to it: 

cb cluster create --name <cluster_name> --cli-input-json <template.json>
