Querying All DCS Instances of a Tenant

Function

This API is used to query DCS instances of a tenant, and allows you to specify query criteria.

URI

GET /v1.0/{project_id}/instances?start={start}&limit={limit}&name={name}&status={status}&id={id}&includeFailure={includeFailure}&isExactMatchName={isExactMatchName}&ip={ip}&tags={key}={value}

Table 1 describes the parameters.

**Table 1** Parameter description
Parameter	Type	Mandatory	Description
project_id	String	Yes	Project ID.
start	Integer	No	Start number for querying DCS instances. It cannot be lower than 1. By default, the start number is 1.
limit	Integer	No	Number of DCS instances displayed on each page. Minimum value: 1 Maximum value: 2000 If this parameter is left unspecified, a maximum of 1000 DCS instances are displayed on each page.
name	String	No	DCS instance name.
id	String	No	Instance ID.
status	String	No	DCS instance status. For details about status, see DCS Instance Statuses.
includeFailure	String	No	An indicator of whether the number of DCS instances that failed to be created will be returned to the API caller. Options: true: The number of DCS instances that failed to be created will be returned to the API caller. false or others: The number of DCS instances that failed to be created will not be returned to the API caller.
isExactMatchName	String	No	An indicator of whether to perform an exact or fuzzy match based on instance name. Options: true: exact match false: fuzzy match Default value: false.
tags	Array of Objects	No	Query based on the instance tag key and value. {key} indicates the tag key, and {value} indicates the tag value. To query instances with multiple tag keys and values, separate key-value pairs with commas (,).
