serverless可以用来创建RDS实例吗?

对于云形成,这是非常直接的。您只需定义一个 AWS::RDS::DBInstance https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/sample-templates-services-us-east-1.html#w2ab2c23c42c13c27

由于可以在Serverless中包含CloudFormation资源,因此可以将其直接添加到 serverless.yml 因此,它由无服务器部署,无需使用单独的CloudFormation部署: https://serverless.com/framework/docs/providers/aws/guide/resources/

https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-rds-dbcluster.html

是的,你肯定可以用cloudformation模板创建rds实例,

"MyDB" : {
 "Type" : "AWS::RDS::DBInstance",
 "Properties" : {
     "DBSecurityGroups" : [
        {"Ref" : "MyDbSecurityByEC2SecurityGroup"}, {"Ref" : "MyDbSecurityByCIDRIPGroup"} ],
     "AllocatedStorage" : "5",
     "DBInstanceClass" : "db.m1.small",
     "Engine" : "MySQL",
     "MasterUsername" : "MyName",
     "MasterUserPassword" : "MyPassword"
 },
 "DeletionPolicy" : "Snapshot"
} 

这个json片段将创建您的RDS实例,完整参考创建您的RDS和Elastic beanstalk请参阅:

希望这会有帮助!
