Example 3: Enabling an AS Group

Updated on 2022-10-08 GMT+08:00

Scenarios

This section describes how to enable an AS group by calling APIs. For details, see Calling APIs.

An AS group consists of a collection of instances that apply to the same scenario. It is the basis for enabling or disabling AS policies and performing scaling actions.

Only enabled AS groups support scaling actions.

Involved APIs

Procedure

  1. Determine the user token that can be used to authenticate the calling of other APIs.

    1. View the user token. For details, see Obtaining a User Token.
    1. Obtain the value of X-Subject-Token in the response header.

  1. Determine the AS group.

    1. View AS groups.
      • API

        URI format: GET /autoscaling-api/v1/{project_id}/scaling_group

        For details, see Querying AS Groups.

      • Example request

        This example shows how to query AS groups with AS configuration ID 1d281494-6085-4579-b817-c1f813be835f.

        GET https://{Endpoint}/autoscaling-api/v1/0605767c2e80d5762fd0c0146a10aaf2/scaling_group?scaling_configuration_id=1d281494-6085-4579-b817-c1f813be835f

        Obtain {endpoint} from Regions and Endpoints.
