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：

查询可用区列表：确定待创建云服务器所在的可用区。
查询云服务器规格详情列表：确定待创建云服务器的规格。
查询镜像列表详情：确定待创建云服务器使用的镜像。
查询网络列表：确定云服务器的网络信息。
创建和导入SSH密钥：设置密钥对登录方式。
创建云服务器：创建密钥对登录鉴权的云服务器。
查询云服务器详情：确认云服务器创建成功。

操作步骤

确定待创建云服务器所在的可用区。

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" 
    }

创建密钥对登录鉴权的云服务器。

接口相关信息

URI格式：POST /v2.1/{project_id}/servers

接口约束及请求参数说明详情，请参见创建云服务器。

本示例是指定image创建云服务器，因此：

block_device_mapping_v2中，“source_type”需设置为“image”，“uuid”设置为选择的镜像ID，“destination_type”设置为“volume”，“boot_index”设置为“0”。
“volume_size”应大于等于镜像元数据中指定的最小值。

设置密码登录方式。

使用非cloud-init镜像创建云服务器时，Windows和Linux系统都使用“adminPass”参数实现密码注入。
使用cloud-init镜像创建云服务器时：

对于Linux系统，只能使用“user_data”进行密码注入，“user_data”字符串长度小于65535，且必须是base64加密的；
对于Windows系统，只能通过元数据“admin_pass”进行密码注入。

创建密码方式登录鉴权的弹性云服务器。

本示例是指定image创建弹性云服务器，因此：
