在aws-cdk上的aws-rds上，可公开访问数据库的设置在哪里?

问题描述

对于AWS RDS，控制台和CLI/API都具有使数据库可公开访问的开关，但是我找不到使用提供的结构通过新的aws-cdk做到这一点的方法.在Cloud Formation类(例如CfnDBInstance)中有一个布尔值，但是我找不到有关如何将其与结构结合使用的文档. CDK非常令人惊叹，除了这一段代码外，它只需几行代码就可以完美地设置所有内容.

With AWS RDS, the console and the CLI/API both have a switch to make the database publicly accessible, but I cannot find a way to do this with the new aws-cdk using the constructs provided. There is a boolean for this in the Cloud Formation classes (e.g. CfnDBInstance), but I can't find documentation on how to use that in combination with the constructs. The CDK is pretty amazing, and it set up everything perfectly with just a few lines of code, except for this one piece.

推荐答案

是否使数据库可公开访问是源自类型为ec2.SubnetSelection的vpcPlacement属性.

Whether the database is made publicly accessible or not is derived from the vpcPlacement prop which is of type ec2.SubnetSelection.

const instance = new rds.DatabaseInstance(this, 'Instance', {
  ... // other props
  vpcPlacement: { subnetType: ec2.SubnetType.PUBLIC }
});
