弹性伸缩 AS

操作步骤

确定调用API鉴权时使用的token。
1. 查询token，详情请参见获取用户Token。
2. 获取响应Header参数中X-Subject-Token对应的值。

确定要进行批量操作的伸缩组。

查询伸缩组列表。

接口相关信息
 URI格式：GET /autoscaling-api/v1/{project_id}/scaling_group

详情请参见查询弹性伸缩组列表。

请求示例
 GET: https://{endpoint}/autoscaling-api/v1/0605767c2e80d5762fd0c0146a10aaf2/scaling_group

{endpoint}信息请从地区和终端节点获取。

选择要操作实例的伸缩组，并记录伸缩组ID。

获取指定伸缩组实例列表。
1. 查询弹性伸缩组中的实例列表。
  - 接口相关信息
     URI格式：GET /autoscaling-api/v1/{project_id}/scaling_group_instance/{scaling_group_id}/list
    
    详情请参见查询弹性伸缩组中的实例列表。
  - 请求示例
     本示例展示了查询ID为e5d27f5c-dd76-4a61-b4bc-a67c5686719a的伸缩组下已启用且处于健康状态的实例。
    
    GET: https://{endpoint}/autoscaling-api/v1/0605767c2e80d5762fd0c0146a10aaf2/scaling_group_instance/e5d27f5c-dd76-4a61-b4bc-a67c5686719a/list?life_cycle_state=INSERVICE&health_status=NORMAL
