What is the service and instance discovery mechanism?![]()
how can I get my service to discover an existing instance which belongs to the service and display the relationship in the GUI. just like the base-kubernetes service, it found a lot instance that existing before the base-kubernetes installed.

Hello Wu,
when a service needs to create a ServiceInstance it calls https://github.com/opencord/xos/blob/5c2ea23b7d2f0a01fc75f37db83f03580fb0ed4f/lib/xos-api/xosapi/convenience/service.py#L69-L90 (note that this method can be overridden by services).
In the case of the kubernetes-service there is a pull_step (that is invoked periodically) that creates the instances by fetching the kubernetes API: https://github.com/opencord/kubernetes-service/blob/master/xos/synchronizer/pull_steps/pull_pods.py#L267-L275
