Retrieves the list of clusters in a folder.

HTTP request

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

Query parameters

Parameter Description
folderId Required. ID of the folder to list clusters in. To get this ID, make a list request. The maximum string length in characters is 50.
pageSize The maximum number of results per page to return. If the number of available results is larger than pageSize, the API returns a nextPageToken that can be used to get the next page of results in the subsequent list requests. Acceptable values are 0 to 1000, inclusive.
pageToken Page token that can be used to iterate through multiple pages of results. To get the next page of results, set pageToken to the nextPageToken returned by the previous list request. The maximum string length in characters is 100.
filter A filter expression that selects clusters 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_-]+. The maximum string length in characters is 1000.

Response

HTTP Code: 200 - OK
