创建实例

功能介绍

创建实例，该接口支持创建按需和包周期计费方式的实例。

调用方法

请参见如何调用API。

URI

POST /v2/{engine}/{project_id}/instances

表1 路径参数
参数	是否必选	参数类型	描述
engine	是	String	消息引擎。缺省值：rabbitmq
project_id	是	String	项目ID，获取方式请参见获取项目ID。

请求参数

表2 请求Body参数
参数	是否必选	参数类型	描述
name	是	String	实例名称。由英文字符开头，只能由英文字母、数字、中划线、下划线组成，长度为4~64的字符。
description	否	String	实例的描述信息。长度不超过1024的字符串。说明： \与"在json报文中属于特殊字符，如果参数值中需要显示\或者"字符，请在字符前增加转义字符\，比如\或者"。
engine	是	String	消息引擎：rabbitmq。
engine_version	是	String	消息引擎的版本。 RabbitMQ版本有：3.8.35。
storage_space	是	Integer	消息存储空间，单位GB。单机RabbitMQ实例的存储空间的取值范围100GB~90000GB。集群RabbitMQ实例的存储空间的取值范围为100GB节点数~90000GB、200GB节点数~90000GB、300GB*节点数~90000GB。
access_user	是	String	认证用户名，只能由英文字母开头且由英文字母、数字、中划线、下划线组成，长度为4~64的字符。
password	是	String	实例的认证密码。复杂度要求：输入长度为8到32位的字符串。必须包含如下四种字符中的两种组合：小写字母大写字母数字特殊字符包括（`~!@#$%^&*()-_=+\|[{}]:'",<.>/?）
vpc_id	是	String	租户VPC ID。获取方法如下：登录虚拟私有云服务的控制台界面，在虚拟私有云的详情页面查找VPC ID。
security_group_id	是	String	租户安全组ID。获取方法如下：登录虚拟私有云服务的控制台界面，在安全组的详情页面查找安全组ID。
subnet_id	是	String	子网ID。获取方法如下：登录虚拟私有云服务的控制台界面，单击VPC下的子网，进入子网详情页面，查找网络ID。
available_zones	是	Array of strings	创建节点到指定且有资源的可用区ID。请参考查询可用区信息获取可用区ID。该参数不能为空数组或者数组的值为空。
product_id	是	String	产品标识。产品ID可以从查询产品规格列表获取。如果产品ID为集群类型（即对应的type为cluster），broker_num字段为必选。
broker_num	否	Integer	代理个数。当产品为单机类型，代理个数只能为1；当产品为集群类型，可选3、5、7个代理个数。产品类型为single时: 1 产品类型为cluster时: 3 5 7

maintain_end	否	String	维护时间窗结束时间，格式为HH:mm。维护时间窗开始和结束时间必须为指定的时间段。结束时间在开始时间基础上加四个小时，即当开始时间为22:00时，结束时间为02:00。该参数不能单独为空，若该值为空，则开始时间也为空，系统分配一个默认结束时间06:00。
enable_publicip	否	Boolean	RabbitMQ实例是否开启公网访问功能。 true：开启 false：不开启
publicip_id	否	String	RabbitMQ实例绑定的弹性IP地址的ID。如果开启了公网访问功能（即enable_publicip为true），该字段为必选。

tags	否	Array of TagEntity objects	标签列表。
bss_param	否	BssParam object	表示包周期计费模式的相关参数。如果为空，则默认计费模式为按需计费；否则是包周期方式。

表3 TagEntity
参数	是否必选	参数类型	描述
key	否	String	标签键。不能为空。对于同一个实例，Key值唯一。长度为1~128个字符（中文也可以输入128个字符）。由任意语种字母、数字、空格和字符组成，字符仅支持_ . : = + - @ 首尾字符不能为空格。
