ListInstances

Lists instances that belongs to the specified host group.

import { cloudApi, serviceClients, Session } from "@yandex-cloud/nodejs-sdk";

const ListHostGroupInstancesRequest =
  cloudApi.compute.host_group_service.ListHostGroupInstancesRequest;

(async () => {
  const authToken = process.env["YC_OAUTH_TOKEN"];
  const session = new Session({ oauthToken: authToken });
  const client = session.client(serviceClients.HostGroupServiceClient);

  const result = await client.listInstances(
    ListHostGroupInstancesRequest.fromPartial({
      hostGroupId: "hostGroupId",
      // pageSize: 0,
      // pageToken: "pageToken",
      // filter: "filter"
    })
  );
  console.log(result);
})();

ListHostGroupInstancesRequest​

hostGroupId : string​

ID of the host group to list instances for. To get the host group ID, use HostGroupService.List request.

pageSize : int64​

The maximum number of results per page to return. If the number of available results is larger than page_size, the service returns a ListHostGroupInstancesResponse.next_page_token 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 page_token to the ListHostGroupInstancesResponse.next_page_token returned by a previous list request.

filter : string​

A filter expression that filters resources listed in the response. The expression consists of one or more conditions united by AND operator: <condition1> [AND <condition2> [<...> AND <conditionN>]].

Each condition has the form <field> <operator> <value>, where:

  1. <field> is the field name. Currently you can use filtering only on the limited number of fields.
  2. <operator> is a logical operator, one of =, !=, IN, NOT IN.
  3. <value> represents a value. String values should be written in double (") or single (') quotes. C-style escape sequences are supported (\" turns to ", \' to ', \\ to backslash). Currently you can use filtering only on the Host.id field. To get the host ID, use HostGroupService.ListHosts request.

ListHostGroupInstancesResponse​

instances : Instance​

Lists instances for the specified host group.

nextPageToken : string​

This token allows you to get the next page of results for list requests. If the number of results is more than ListHostGroupInstancesRequest.page_size, use next_page_token as the value for the ListHostGroupInstancesRequest.page_token query parameter in the next list request. Each subsequent list request will have its own next_page_token to continue paging through the results.
