Amazon web services AWS RDS代理不可用-如何调试？
我已经使用Terraform创建了一个RDS代理。然而，它似乎不起作用 我的应用程序代码无法连接到代理超时，aws rds DESCRIPE db proxy targets提供以下信息： { 目标：[ { 终点：mydb.aaaa.eu-west-2.rds.amazonaws.com， RdsResourceId:mydb， 港口：5432， 类型：RDS\U实例， TargetHealth：{ 状态：不可用， 说明：由于内部错误，DBProxy目标不可用 } } ] } 我如何进行调试 下面是代理的Terraform脚本。RDS实例在别处有描述，但正在工作Amazon web services AWS RDS代理不可用-如何调试？,amazon-web-services,terraform,amazon-rds,amazon-rds-proxy,Amazon Web Services,Terraform,Amazon Rds,Amazon Rds Proxy,我已经使用Terraform创建了一个RDS代理。然而，它似乎不起作用 我的应用程序代码无法连接到代理超时，aws rds DESCRIPE db proxy targets提供以下信息： { 目标：[ { 终点：mydb.aaaa.eu-west-2.rds.amazonaws.com， RdsResourceId:mydb， 港口：5432， 类型：RDS\U实例， TargetHealth：{ 状态：不可用， 说明：由于内部错误，DBProxy目标不可用 } } ] } 我如何进行调试 下

要使其正常工作，您需要做几件事： 密码中存储的用户名/密码 来自Lambda->RDS代理的安全组规则 来自RDS代理->RDS的安全组规则 同一VPC中的RDS代理、Lambda和RDS RDS代理角色可以访问密钥 一个有用的调试查询是： aws rds描述数据库代理目标-数据库代理名称 要了解它返回的错误消息，请参阅 用户名/密码是最难发现的，因为Terraform还不支持它。您需要做的是在Terraform中构造一个JSON字符串，该字符串与RDS代理可以理解的内容相匹配：
