GET https://compute.api.cloud.yandex.net/compute/v1/placementGroups/{placementGroupId}/instances

Path parameters

Field

Description

placementGroupId

string

Required field. ID of the placement group to list instances for.

To get the placement group ID, use PlacementGroupService.List request.

Query parameters

Field

Description

pageSize

string (int64)

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

Response

HTTP Code: 200 - OK

Field

Description

instances[]

Instance

Lists instances for the specified placement group.

string

This token allows you to get the next page of results for list requests. If the number of results
is more than ListPlacementGroupInstancesRequest.pageSize, use
nextPageToken as the value
for the ListPlacementGroupInstancesRequest.pageToken query parameter
