"Domain in DNS Specification is not valid" error during VCF deployment

Products

• VMware SDDC Manager / VCF Installer

Issue/Introduction

• During step 9 (Validate & Deploy) of the VCF Fleet deployment wizard, the Deployment Specification validation task fails. The user interface flags the following error: Domain '####' in DNS Specification is not valid
• The UI outputs the remediation instruction: Provide valid FQDN for Domain '####' in the DNS Specification.
• Subsequent validations show as Failed with the message: Validation skipped due to an issue found in another task that this validation relies on.
  

Environment

VCF 9.0.x

Cause

An IP address is incorrectly supplied in the DNS specification field during the initial deployment of the VCF Installer appliance instead of a Fully Qualified Domain Name (FQDN). The VCF 9 Installer validation strictly requires an FQDN for the deployment specification. The inputted IP address fails this string validation, triggering the deployment specification failure.

Resolution

Follow these steps to resolve the validation failure:

1. Delete the existing VCF Installer appliance.
2. Redeploy the VCF Installer appliance.
3. Supply a valid FQDN in the DNS specification fields during configuration.
4. Proceed with the deployment wizard to pass the validation checks.
