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

2、 根据实际需要选择规格,并记录规格的ID。
步骤三:确定待创建云服务器使用的镜像。
1、查询镜像。
(1)接口相关信息
URI格式:GET /v2.1/{project_id}/images/detail
(2)请求示例
GET: https://{endpoint}/v2.1/74610f3a5ad941998e91f076297ecf27/images/detail

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。
1、创建非cloud-init镜像、密码方式登录鉴权的弹性云服务器。
(1)接口相关信息
URI格式:POST /v2.1/{project_id}/servers
(2)请求示例

(3)响应示例
{ "server": { "security_groups": [ { "name": "default" } ], "OS-DCF:diskConfig": "MANUAL", "links": [ { "rel": "self", "href": "https://None/v2.1/74610f3a5ad941998e91f076297ecf27/servers/73991cff-37c6-491a-9a8a-377397729fce" }, { "rel": "bookmark", "href": "https://None/74610f3a5ad941998e91f076297ecf27/servers/73991cff-37c6-491a-9a8a-377397729fce" } ], "id": "73991cff-37c6-491a-9a8a-377397729fce", "adminPass": "NOVAGLANCEI@123" } }
