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两种计费方式的实例。

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。
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。取值填写为：kafka。
engine_version	是	String	消息引擎的版本。取值填写为： 1.1.0 2.7 3.x
broker_num	是	Integer	代理个数。
storage_space	是	Integer	消息存储空间，单位GB。 Kafka实例规格为c6.2u4g.cluster时，存储空间取值范围300GB ~ 300000GB。 Kafka实例规格为c6.4u8g.cluster时，存储空间取值范围300GB ~ 600000GB。 Kafka实例规格为c6.8u16g.cluster时，存储空间取值范围300GB ~ 1500000GB。 Kafka实例规格为c6.12u24g.cluster时，存储空间取值范围300GB ~ 1500000GB。 Kafka实例规格为c6.16u32g.cluster时，存储空间取值范围300GB ~ 1500000GB。
access_user	否	String	当ssl_enable为true时，该参数必选，ssl_enable为false时，该参数无效。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	否	String	当ssl_enable为true时，该参数必选，ssl_enable为false时，该参数无效。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三种组合：小写字母大写字母数字特殊字符包括（`~!@#$%^&*()-_=+\|[{}]:'",<.>/?）和空格，并且不能以-开头
vpc_id	是	String	虚拟私有云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	指定实例所属的安全组。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	子网信息。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。创建Kafka实例，支持节点部署在1个或3个及3个以上的可用区。在为节点指定可用区时，用逗号分隔开。
product_id	是	String	产品ID。产品ID可以从查询产品规格列表获取。
maintain_begin	否	String	维护时间窗开始时间，格式为HH:mm。
maintain_end	否	String	维护时间窗结束时间，格式为HH:mm。
enable_publicip	否	Boolean	是否开启公网访问功能。默认不开启公网。 true：开启 false：不开启
publicip_id	否	String	实例绑定的弹性IP地址的ID。以英文逗号隔开多个弹性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。
ssl_enable	否	Boolean	是否打开SSL加密访问。实例创建后将不支持动态开启和关闭。 true：打开SSL加密访问。 false：不打开SSL加密访问。
kafka_security_protocol	否	String	开启SASL后使用的安全协议，如果开启了SASL认证功能（即ssl_enable=true），该字段为必选。若该字段值为空，默认开启SASL_SSL认证机制。实例创建后将不支持动态开启和关闭。 SASL_SSL: 采用SSL证书进行加密传输，支持账号密码认证，安全性更高。 SASL_PLAINTEXT: 明文传输，支持账号密码认证，性能更好，建议使用SCRAM-SHA-512机制。
sasl_enabled_mechanisms	否	Array of strings	开启SASL后使用的认证机制，如果开启了SASL认证功能（即ssl_enable=true），该字段为必选。若该字段值为空，默认开启PLAIN认证机制。选择其一进行SASL认证即可，支持同时开启两种认证机制。取值如下： PLAIN: 简单的用户名密码校验。 SCRAM-SHA-512: 用户凭证校验，安全性比PLAIN机制更高。
retention_policy	否	String	磁盘的容量到达容量阈值后，对于消息的处理策略。取值如下： produce_reject：表示拒绝消息写入。 time_base：表示自动删除最老消息。
ipv6_enable	否	Boolean	是否开启ipv6。仅在虚拟私有云支持ipv6时生效。
disk_encrypted_enable	否	Boolean	是否开启磁盘加密。
disk_encrypted_key	否	String	磁盘加密key，未开启磁盘加密时为空
connector_enable	否	Boolean	是否开启消息转储功能。默认不开启消息转储。
enable_auto_topic	否	Boolean	是否打开kafka自动创建topic功能。 true：开启 false：关闭当您选择开启，表示生产或消费一个未创建的Topic时，会自动创建一个包含3个分区和3个副本的Topic。默认是false关闭。
storage_spec_code	是	String	存储IO规格。取值范围： dms.physical.storage.high.v2：使用高IO的磁盘类型。 dms.physical.storage.ultra.v2：使用超高IO的磁盘类型。如何选择磁盘类型请参考《云硬盘产品介绍》的“磁盘类型及性能介绍”。
enterprise_project_id	否	String	企业项目ID。若为企业项目账号，该参数必填。
tags	否	Array of TagEntity objects	标签列表。
arch_type	否	String	CPU架构。当前只支持X86架构。取值范围： X86
vpc_client_plain	否	Boolean	VPC内网明文访问。
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

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。
value	否	String	标签值。长度为0~255个字符（中文也可以输入255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。

is_auto_pay	否	Boolean	下单订购后，是否自动从客户的账户中支付，而不需要客户手动去进行支付。取值范围： true：是（自动支付） false：否（需要客户手动支付）默认为手动支付。
period_type	否	String	订购周期类型。取值范围： month：月 year：年 chargingMode为prePaid时生效且为必选值。
period_num	否	Integer	订购周期数。取值范围： periodType=month（周期类型为月）时，取值为[1，9]； periodType=year（周期类型为年）时，取值为[1，3]； chargingMode为prePaid时生效且为必选值。
