通过API创建云服务器的9个步骤（以指定镜像方式创建云服务器为例）

步骤一：确定待创建云服务器所在的可用区。

1、查询可用区。

（1）接口相关信息

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

（2）请求示例

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

（3）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。

步骤二：确定待创建云服务器的规格。

1、查询云服务器规格信息。

（1）接口相关信息

URI格式：GET/v2.1/{project_id}/flavors/detail{?minDisk,minRam,is_public,sort_key,sort_dir}

其中，"?"后的字段为查询规格时可选的查询检索参数。

（2）请求示例

GET: https://{endpoint}/v2.1/74610f3a5ad941998e91f076297ecf27/flavors/detail

（3）响应示例

{  "flavors": [    {      "name": "c1.2xlarge",      "links": [        {          "href": "https://xxx/v2.1/74610f3a5ad941998e91f076297ecf27/flavors/c1.2xlarge",          "rel": "self"        },        {          "href": "https://xxx/74610f3a5ad941998e91f076297ecf27/flavors/c1.2xlarge",          "rel": "bookmark"        }      ],      "ram": 8192,      "OS-FLV-DISABLED:disabled": false,      "vcpus": 8,      "swap": "",      "os-flavor-access:is_public": true,      "rxtx_factor": 1,      "OS-FLV-EXT-DATA:ephemeral": 0,      "disk": 0,      "id": "c1.2xlarge"    }]}

2、 记录响应消息体中的name信息。如本例中为"demo2"。

步骤六：创建密钥对登录鉴权的云服务器。

（1）接口相关信息

URI格式：POST /v2.1/{project_id}/servers

说明：

本示例是指定image创建云服务器，因此：

● block_device_mapping_v2.1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。

（2）请求示例

POST: https://{endpoint}/v2.1/74610f3a5ad941998e91f076297ecf27/servers

Body：

{    "server": {        "flavorRef": "c1.large",        "name": "zttestvm1",        "block_device_mapping_v2.1": [{            "source_type": "image",            "destination_type": "volume",            "volume_type": "SATA",            "volume_size": "40",            "delete_on_termination": "true",            "uuid": "11e8f727-d439-4ed1-b3b8-33f46c0379c4",            "boot_index": "0"        }],        "networks": [{            "uuid": "fb68519f-a7c0-476e-98d4-2e4cf6de6def"        }],        "key_name": "demo2",        "availability_zone": "az_test_01"    }}

（3）响应示例

{  "server": {    "security_groups": [      {        "name": "default"      }    ],    "OS-DCF:diskConfig": "MANUAL",    "links": [      {        "rel": "self",        "href": "https://None/v2.1/74610f3a5ad941998e91f076297ecf27/servers/6d311127-bce1-48db-bf0f-cac9f8f7f077"      },      {        "rel": "bookmark",        "href": "https://None/74610f3a5ad941998e91f076297ecf27/servers/6d311127-bce1-48db-bf0f-cac9f8f7f077"      }    ],    "id": "6d311127-bce1-48db-bf0f-cac9f8f7f077",    "adminPass": "WcC4QoVZPXpV"  }}

步骤七：设置密码登录方式。

（1）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。

（2）使用cloud-init镜像创建云服务器时：

l 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；

l 对于Windows系统，只能通过元数据"admin_pass"进行密码注入。

步骤八：创建密码方式登录鉴权的弹性云服务器。

说明：

本示例是指定image创建弹性云服务器，因此：

（1）block_device_mapping_v2.1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"。

（2）"volume_size"应大于等于镜像元数据中指定的最小值。
