Does Cloudbreak support launching instances with Specific hostname

Expert Contributor

Hi All,

We are trying to use Cloudbreak for launching hdp cluster on EC2 instances. When we launch the cluster, by default it takes hostname as "ip-XX-XXX-XX-XX" for Instances.

As per our understanding, we need two files (hostmap.json & cluster_config.json) to launch the cluster. In Cloudbreak, we don't have a provision to select two files. We can select only one file.

Does Cloudbreak support launching instances with specific hostname?

Thanks..

Hi @Shyam Shaw,

You are right, 1.16.1 doesn't contain the advanced options, but you can use the Cloudbreak wide environment variable. Unfortunately it will apply domain name for all the clusters what you spin up.

Hi @Shyam Shaw,

You have two options. First there is a Cloudbreak wide environment variable what you can set in your Profile called `CB_HOST_DISCOVERY_CUSTOM_DOMAIN`. This will applied all the clusters where you don't specify any domain name.

The second option is under "Advanced Options" on the cluster create form (or Cloudbreak shell). If yoou open the options you should see the following inputs:

  • Custom Domain
  • Use Cluster Name As Subdomain
  • Use Hostgroup As Hostname
  • Custom Hostname

Hi @rkovacs,

Thanks for your response but we are unable to find the options under "Advanced Options". Could you please guide us on the exact path or if you could provide any screenshot. We are using Cloudbreak Deployer 1.16.1.

Can you tell which version DOES contain these custom domain option? And how to deploy on Azure with ARM?

This is now a deal-breaker for us... so it can also be an RC or DEV version.. we are testing 1.16.4 now

Hi @Nic Swart,

Sorry for the late answer. Cloudbreak 1.16.5 has the environemnt variable CB_HOST_DISCOVERY_CUSTOM_DOMAIN.
