通过此模板,您可以快速创建一个私有网络下的云数据库(RDS),数据库类型为MySQL 5.7。该模版首先会自动创建一个私有网络和子网,然后在此网络下创建按配置收费模式的MySQL5.7。
创建成功的资源栈,输出MySQL实例的ID和内网访域名。
注意
:目前RDS不支持snapshot功能,即删除数据库的时候,不支持备份RDS数据。删除该资源类型时,请您确认好数据是否需要备份,如有需要,请手动导出数据后再去删除。
----------
模板包含几个主要部分。Format Version 部分是必需部分。模板中的某些部分可以任何顺序显示。但是,在您构建模板时,使用以下列表的逻辑顺序可能会很有用,因为一个部分中的值可能会引用上一个部分中的值。列表简要概述了每个部分。
Format Version
(必选):JDRO支持的模板版本号,当前版本号:2018-10-01
Description
(可选):一个描述模板的文本字符串,对模板进行详细描述。
Parameters
(可选):定义创建资源栈时,模板用户可以定制化的参数。在运行时 (创建或更新堆栈时) 传递到模板。您可在模板的 Resources 和 Outputs 部分中引用定义的这些参数。使用参数可以增强模板的灵活性,提高复用性。
Mappings
(可选):可用来指定条件参数值的密钥和关键值的映射,与查找表类似。您可通过使用 Resources 和 Outputs 部分中的 Fn::FindInMap 内部函数将键与相应的值匹配。
Conditions
(可选):Conditions 使用 Fn::And、Fn::Or、Fn::Not、Fn::Equals 等定义条件。在创建或更新资源栈时,系统先计算模板中的所有条件,然后再创建资源。创建与 true 条件关联的所有资源,忽略与 false 条件关联的所有资源。
Resources
(可选):用于详细定义使用该模板创建的资源栈所包含的资源,包括资源间的依赖关系、配置细节等。
Outputs
(可选):用于输出一些资源属性等有用信息。可以通过 API 或控制台获取输出的内容。
