Instance Registration
Start the Broker service before you start the Orchestrator service. For more information, see Broker Service.
After you start the Orchestrator service, it registers by calling the /v1/instance/register
API of the Broker service. On successful registration, the Broker service returns the instance ID to the registering instance. This instance ID is used by the Orchestrator service for further communication with other Orchestrator instances or southbound systems.
In cases where an instance encounters a client-side issue (indicated by a 4xx error) during the registration process with the Broker service, the Orchestrator implements a retry mechanism to ensure successful registration.
