Querying a List of Clusters with Specified Tags

Function

This API is used to filter clusters by tag.

By default, clusters and tags are sorted in descending order of creation time.

Constraints

None

Debugging

You can debug this API in API Explorer. Automatic authentication is supported. API Explorer can automatically generate sample SDK code and provide the sample SDK code debugging.

Request Parameters

**Table 2** Request body parameters
Parameter	Mandatory	Type	Description
tags	No	Array of TagWithMultiValue objects	Explanation The returned result contains the resources corresponding to all tags in this parameter. Constraints The structure body is mandatory. A maximum of 10 tag keys are allowed in each query operation. The tag key cannot be left blank or set to the empty string. One tag key can have up to 10 tag values. For details about the parameters, see Table 3.
tags_any	No	Array of TagWithMultiValue objects	Explanation The returned result contains the resources corresponding to any tag in this parameter. Constraints The structure body is mandatory. A maximum of 10 tag keys are allowed in each query operation. The tag key cannot be left blank or set to the empty string. One tag key can have up to 10 tag values. Keys must be unique and values of a key must be unique. For details about the parameters, see Table 3.
not_tags	No	Array of TagWithMultiValue objects	Explanation The returned result does not contain the resources corresponding to all tags in this parameter. Constraints The structure body is mandatory. A maximum of 10 tag keys are allowed in each query operation. The tag key cannot be left blank or set to the empty string. One tag key can have up to 10 tag values. Keys must be unique and values of a key must be unique. For details about the parameters, see Table 3.
not_tags_any	No	Array of TagWithMultiValue objects	Explanation The returned result does not contain the resources corresponding to any tag in this parameter. Constraints The structure body is mandatory. A maximum of 10 tag keys are allowed in each query operation. The tag key cannot be left blank or set to the empty string. One tag key can have up to 10 tag values. Keys must be unique and values of a key must be unique. For details about the parameters, see Table 3.
limit	No	Integer	Explanation Number of query records. Constraints If you set action to count, this parameter is not required. If action is set to filter, the default value of this parameter is 1000. Value range 1-1000 Default value N/A
offset	No	Integer	Explanation Index position. The query starts from the next data record indexed by this parameter. You do not need to specify this parameter when you query resources on the first page. When you query resources on subsequent pages, set this parameter to the location returned in the response body for the previous query. Constraints If you set action to count, this parameter is not required. If action is set to filter, the default value is 0. Value range ≥0 Default value N/A
action	Yes	String	Explanation Operation ID (only filter and count is available). filter: The query is paginated. count: The total number of records is returned by search condition. Constraints N/A Value range filter: Perform pagination query. count: Query the total number of resources. Default value N/A
matches	No	Array of Match objects	Explanation Search field. key indicates the field to be matched, for example, resource_name. value indicates the matched value. This field is a fixed dictionary value. Determine whether fuzzy match is required based on different fields. For example, if key is resource_name, fuzzy search is used by default. If value is an empty string, exact match is used. For details about the parameters, see Table 4. Constraints N/A

**Table 3** TagWithMultiValue
Parameter	Mandatory	Type	Description
key	Yes	String	Explanation Tag key. Constraints N/A Value range A tag key can contain letters, digits, spaces, and special characters (_.:=+-@), but cannot start or end with a space or start with _sys_. Default value N/A
values	No	Array of strings	Explanation Tag value. Constraints A tag value can contain letters, digits, spaces, and special characters (_.:=+-@), but cannot start or end with a space or start with _sys_.

**Table 4** Match
Parameter	Mandatory	Type	Description
key	No	String	Explanation Key. Currently, only resource_name is available, indicating the cluster name. Other keys will be supported later. Constraints N/A Value range The value can contain 1 to 64 characters. Default value N/A
value	No	String	Explanation Value. A value can contain a maximum of 64 Unicode characters. Constraints N/A Value range The value can contain 0 to 64 characters. Default value N/A
