Products

• VCF Operations/Automation (formerly VMware Aria Suite)

Issue/Introduction

This article provides the steps to correctly configure Aria Orchestrator to be accessible via a CNAME (DNS alias) in addition to its primary hostname.

Environment

VMware Aria Orchestrator, standalone/external appliance.

Resolution

To successfully configure and use a CNAME, you must first meet all prerequisites and then run the authentication command to register the CNAME FQDN.
1. Prerequisites
Before attempting to register the CNAME, you must verify the following:

• Certificate: The certificate applied to Orchestrator must contain both the original hostname and the CNAME DNS record in the Subject Alternative Name (SAN) field.
• Domain Match: The CNAME FQDN domain value must match the same domain name as the originally deployed hostname.
• Supported: vro-host.domain.com (Host) and orchestrator.domain.com (CNAME)
• Not Supported: vro-host.domain.com (Host) and orchestrator.other-domain.com (CNAME)

2. Configuration Step
After all prerequisites are met, run the following command from the appliance command line to register the CNAME using the -FQDN switch.

vracli vro authentication set -p vsphere -hn <vCenter FQDN> -u [email protected] --tenant vsphere.local --admin-group Administrators --admin-group-domain vsphere.local --fqdn <CNAME_FQDN>
