Method listInstances

Written by

Lists instances that belongs to the specified host group.

HTTP request

GET https://compute.api.cloud.yandex.net/compute/v1/hostGroups/{hostGroupId}/instances

Path parameters

Parameter Description
hostGroupId Required. ID of the host group to list instances for. To get the host group ID, use list request. The maximum string length in characters is 50.

Query parameters

Parameter Description
pageSize The maximum number of results per page to return. If the number of available results is larger than pageSize, the service returns a nextPageToken that can be used to get the next page of results in subsequent list requests. The maximum value is 1000.
pageToken Page token. To get the next page of results, set pageToken to the nextPageToken returned by a previous list request. The maximum string length in characters is 100.
filter A filter expression that filters resources listed in the response. Currently you can use filtering only on the id field. To get the host ID, use listHosts request. The maximum string length in characters is 1000.

Response

HTTP Code: 200 - OK
