Doc Text:	In the current release, Metrics Store adds support for a flat DNS environment without subdomains. This capability helps you satisfy security policies that mandate having a "flat" DNS environment with no submains. To enable this capability, you add a suffix to the master0 virtual machine when you configure networking for Metrics Store virtual machines. For example, if you set 'openshift_ovirt_machine_suffix' to 'prod' and 'public_hosted_zone' is 'example.com', then the metrics store virtual machine will be called 'master-prod0.example.com'.

Description Robert McSwain 2019-12-11 15:17:50 UTC

Description of problem:
Security policy mandates that we maintain a "flat" DNS environment -- no submains.  Components of the RHV 4.3 Metrics Store installation require subdomains.  However, code can be altered to support custom host names that support a "flat" DNS environment.

Version-Release number of selected component (if applicable):
RHV 4.3/4.4

Expected Behavior:
RHV will support not using subdomains for use in a "flat" DNS environment 

Actual Behavior:
Currently RHV and Metrics Store require DNS subdomains.

Comment 1 Shirly Radco 2020-01-05 12:11:43 UTC

This fix adds an option to add a suffix to master0 VM.

Example:
If user sets 'openshift_ovirt_machine_suffix' to 'prod' and
'public_hosted_zone' is 'example.com',
Then the metrics store vm will be called 'master-prod0.example.com'.

Comment 4 Guilherme Santos 2020-01-15 15:58:01 UTC

Verified on:
ovirt-engine-metrics-1.3.6.2-1.el7ev.noarch

Steps:
1. Followed metrics installation tutorial until step 4 (https://access.redhat.com/documentation/en-us/red_hat_virtualization/4.3/html/metrics_store_installation_guide/installing_metrics_store#Creating_the_metrics_store_virtual_machines)
2. Added 'openshift_ovirt_machine_suffix' variable to 'test' on metrics-store-config.yml
3. Filled the 'public_hosted_zone' as redhat.com
4. Continued with the tutorial until the step to run the ovirt-metrics-store-installation playbook to create the virtual machines
(included)
5. On the engine, checked the new created VMs
6. Finished deployment of metrics (according with tutorial)
7. Checked Kibana discovery tab

Results:
5. master0 vm created successfully with its name as master-test0.redhat.com
7. metrics fully working as expected
