Enabling an AS Group

Scenario

  • 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.

Precautions

  • If you use a token for authentication, you must call the IAM API to obtain the user's token and add X-Auth-Token to the request message header of ECS API you call.
  • The validity period of the token obtained from the IAM service is 24 hours. If you want to use a token for authentication, you can cache it to avoid frequently calling the IAM API.

Involved APIs

  • IAM API used to obtain the token
  • API used to query AS groups
  • API used to enable or disable an AS group

Procedure

  1. For details about token authentication, see Token Authentication.
  2. Send GET https://AS endpoint/autoscaling-api/v1/{tenant_id}/scaling_group to obtain AS groups. Use the ID of one of the AS groups as the URI parameter scaling_group_id for enabling an AS group. For the response parameters of the API used to query AS groups, see section Response Parameters for Querying AS Groups.
  3. Send POST https://AS endpoint/autoscaling-api/v1/{tenant_id}/scaling_group/{scaling_group_id}/action to enable the AS group. For detailed parameters, see section "Enabling or Disabling an AS Group" in the Auto Scaling API Reference.
    Specify the following parameters in the request body:
    {
    "action": "resume"
}
