创建弹性云服务器

场景描述

本章节指导用户通过API创建云服务器。API的调用方法请参见如何调用API

创建云服务器时,支持通过卷和镜像两种方式进行创建。本节以指定镜像的方式为例,介绍如何创建云服务器

约束限制

该接口创建出来的是按需付费的实例。

涉及接口

创建云服务器时,需要进行规格查询、可用区查询、云硬盘创建等操作,涉及的接口如下:

操作步骤

  1. 确定待创建云服务器所在的可用区。

    1. 查询可用区。
      • 接口相关信息

        URI格式:GET /v2.1/{project_id}/os-availability-zone

        详情请参见查询可用区列表

      • 请求示例

        GET https://{endpoint}/v2.1/74610f3a5ad941998e91f076297ecf27/os-availability-zone

        {endpoint}信息请从地区和终端节点获取。

      • 响应示例
         {
          "availabilityZoneInfo": [
            {
              "hosts": null,
              "zoneState": {
                "available": true
              },
              "zoneName":"zone_01" 
            },
            {
              "hosts": null,
              "zoneState": {
                "available": true
              },
              "zoneName": "zone_01" 
            }
          ]
        }
    2. 根据实际需要选择可用区,并记录可用区的zoneName。

  2. 确定待创建云服务器的规格。

    1. 查询云服务器规格信息。
      • 接口相关信息

        URI格式:GET /v1/{project_id}/cloudservers/flavors?availability_zone={availability_zone}

        其中,“?”后的字段为查询规格时可选的查询检索参数,详情请参见查询规格详情和规格扩展信息列表

      • 请求示例

        GET https://{endpoint}/v1/74610f3a5ad941998e91f076297ecf27/cloudservers/flavors?availability_zone=zone_01

        {endpoint}信息请从地区和终端节点获取。

        availability_zone的值“zone_01”通过步骤1获取。
