Using Falcon to cleanup Satellite host records that belong to terminated OSP instances

Overview

In an environment where OpenStack instances are automatically subscribed to Satellite, it is important that Satellite is notified of terminated instances so that is can safely delete its host record. Not doing so will:

  • Exhaust the available subscriptions, leading to unsubscribed hosts not being able to apply updates and security errata.
  • In the event that an emergency security errata needs to be deployed across the organization, Satellite administrators would be unable to determine if a host was either off or terminated, leading to uncertainty with their security posture.

In smaller environments, where one team is responsible for both OSP and Satellite, it’s possible to have one system administrator do this by using their administrator level access across both systems to determine which host records can be safely deleted in Satellite when the corresponding instance no longer exists.
