(aws-rds): Can't create RDS instance of read replication from source RDS instance #16934
Description
General Issue
The Question
I want to create an RDS read replica from the source RDS instance, but it seems not working.
I follow the RDS of CDK documentation writes the code below...
Reproduction Steps
import * as cdk from '@aws-cdk/core';
import * as ec2 from '@aws-cdk/aws-ec2';
import * as rds from '@aws-cdk/aws-rds';
import { Duration } from '@aws-cdk/core'
export interface RdsStackProps extends cdk.StackProps {
vpc: ec2.Vpc;
}
export class RdsStack extends cdk.Stack {
private vpc: ec2.Vpc;
constructor(scope: cdk.Construct, id: string, props: RdsStackProps ) {
super(scope, id, props)
// Make the vpc variable accessialbe
const vpc = props.vpc
// Create RDS
const master = new rds.DatabaseInstance(this, 'Master', {
instanceIdentifier: 'master',
vpc,
vpcSubnets: {
subnetType: ec2.SubnetType.PRIVATE_WITH_NAT
},
engine,
credentials: rds.Credentials.fromGeneratedSecret('pgadmin'),
instanceType: ec2.InstanceType.of(ec2.InstanceClass.T3, ec2.InstanceSize.SMALL),
multiAz: false,
securityGroups: [ securitygroup2 ],
availabilityZone: vpc.availabilityZones[0],
deletionProtection: false,
storageType: rds.StorageType.IO1,
iops: 1000,
maxAllocatedStorage: 1000,
enablePerformanceInsights: true,
performanceInsightRetention: rds.PerformanceInsightRetention.DEFAULT,
backupRetention: Duration.days(7),
storageEncrypted: true,
copyTagsToSnapshot: true,
});
// Create minion RDS of reading replication from a master
const minion = new rds.DatabaseInstanceReadReplica(this, 'ReadReplica', {
instanceIdentifier: 'minion',
vpc,
vpcSubnets: {
subnetType: ec2.SubnetType.PRIVATE_WITH_NAT
},
sourceDatabaseInstance: master,
instanceType: ec2.InstanceType.of(ec2.InstanceClass.T3, ec2.InstanceSize.SMALL),
multiAz: false,
securityGroups: [ securitygroup2 ],
availabilityZone: vpc.availabilityZones[1],
deletionProtection: false,
storageType: rds.StorageType.IO1,
iops: 1000,
maxAllocatedStorage: 1000,
enablePerformanceInsights: true,
performanceInsightRetention: rds.PerformanceInsightRetention.DEFAULT,
backupRetention: Duration.days(7),
storageEncrypted: true,
});
}

Other information
Even I try to drop these parameters by the minion server, like allocated storage, maxAllocatedStorage, and IOPS. but it seems still not working, the error message always told me that "You must specify both the storage size and iops when modifying the storage size or iops on a DB instance that has iops. (Service: AmazonRDS; Status Code: 400; Error Code: Invali dParameterCombination; Request ID: cd0ad978-1cce-4731-9291-8b2d1ae99693; Proxy: null)".
