Written by
Updated at December 17, 2024

Retrieves the list of OpenSearch clusters that belong to the specified folder.

HTTP request

GET https://mdb.api.cloud.yandex.net/managed-opensearch/v1/clusters

Query parameters

Field

Description

folderId

string

Required field. ID of the folder to list OpenSearch clusters in.

To get the folder ID, use a yandex.cloud.resourcemanager.v1.FolderService.List request.

pageSize

string (int64)

The maximum number of results per page to return.

If the number of available results is larger than pageSize, the service returns
a ListClustersResponse.nextPageToken that can be used to get the next page of results in subsequent list requests.

pageToken

string

Page token. To get the next page of results, set pageToken to the ListClustersResponse.nextPageToken
returned by the previous list request.

filter

string

A filter expression that filters resources listed in the response.

The expression must specify:

  1. The field name. Currently you can only use filtering with the Cluster.name field.

  2. An = operator.

  3. The value in double quotes ("). Must be 1-63 characters long and match the regular expression [a-zA-Z0-9_-]+.

Response

HTTP Code: 200 - OK
