**Table 3** Response body parameters
Parameter	Type	Description
api_version	String	API version. Fixed value: v1.
kind	String	API type. Fixed value: ComponentConfiguration.
items	Array of Instance objects	Component instance list.

**Table 4** Instance
Parameter	Type	Description
id	String	Instance ID.
name	String	Instance name.
status	String	Definition Instance status. Constraints N/A. Range creating: The instance is being created. Pre-operations such as pulling the container image and initializing the container are being performed. The container is not ready for running. running: The instance is running properly. The instance has started, and at least one container is running properly. The overall functions meet the expectation. abnormal: The instance is not running properly. The instance status is not as expected due to reasons such as health check failures and insufficient resources (for example, insufficient CPU or memory). You need to check the event logs to locate the fault. failed: The instance fails to run. At least one container exits in a non-zero state (that is, an error occurs during running), and the entire system is unavailable. terminating: The instance is being terminated. Generally, this status is caused by user operations such as deletion and update. The instance is being stopped and its resources (such as memory and network connections) are being cleared. Default Value N/A.
