接口格式

方法

URI

说明

POST

/v2.0/lbaas/pools/{pool_id}/members

添加属于某个后端云服务器组的后端云服务器。

接口约束

  • 属于一个pool的两个member不能有相同的address和port。
  • 创建member时指定的子网必须和VIP所在子网处在同一个VPC下。
  • admin_state_up参数必须是true。

具体步骤

  1. 设置请求消息头。Postman中设置好头部信息,将获取到的Token放入头部,如下图:

  2. 在Body标签中填写请求消息体。

  3. 查询虚拟机的subnet_id和主网卡IP。

    填写URL。

    GET https://{VPCEndpoint}/v2.0/ports?device_id={ecs_id}

    在响应体中获取primary_interface为true的port的subnet_id和ip_address。响应体示例如下:

    {
        "ports": [
            {
                "id": "4813697b-62ba-4f4b-90e5-13bbbdec7198",

            }
        ]
    }

  4. 填写URL。

    https://{ELBEndpoint}/v2.0/lbaas/pools/{pool_id}/members

  5. 发送请求。body体中的subnet_id和address为步骤3中获取的值,选择请求方法为POST,点击Send按钮,得到服务端响应。

    {
        "member": {
            "name": "member4j",
            "weight": 1,
            "admin_state_up": false,
            "subnet_id": "8d944cda-1f29-4035-9681-ad8c5117fbc5",
            "tenant_id": "0d0bf0e8fb564cc9abbe526dbdca9248",
            "address": "192.168.0.11",
            "protocol_port": 8080,
            "id": "97f18d73-e97d-434c-8cb7-3274a83dda73",
            "operating_status": "ONLINE"
        }
    }
