Referring back to the preceding example, it is clear that you need to configure at least two additional supporting resources for the RDS instance:
- ApplicationDatabaseSecurityGroup: A security group resource that defines the ingress and egress security rules applied to the RDS instance.
- ApplicationDatabaseSubnetGroup: A list of subnets that the RDS instance can be deployed to.
In addition to these resources, the following example demonstrates we also need to add a few more:
...Resources: ApplicationDatabase: Type: AWS::RDS::DBInstance Properties: Engine: MySQL EngineVersion: 5.7 DBInstanceClass: db.t2.micro AllocatedStorage: 10 StorageType: gp2 MasterUsername: todobackend MasterUserPassword: Ref: DatabasePassword ...
