CloudFormation returns Internal Failure when changing existing RDS Instance parameters #6542

robertd · 2020-03-02T17:25:40Z

Check #6439 for more details.

AWS Support Case ID: 6844571841

We are having issues applying any kind of changes to an existing RDS stack. We're using aws-cdk in Typescript. AWS Support noted that Python version worked for them running on aws-cdk v1.18.0. There is a strong possibility this may be a CloudFormation issue, but we're looking into figuring out reproduction steps.

aws-cdk team members aware of this issue: @nija-at (through #6439) @MrArnoldPalmer (through Gitter)

aws-cdk code:

    const dbInstance = new rds.DatabaseInstance(this, "VectorRds", {
      instanceIdentifier,
      engine: rds.DatabaseInstanceEngine.POSTGRES,
      removalPolicy: cdk.RemovalPolicy.DESTROY,
      engineVersion,
      instanceClass: ec2.InstanceType.of(ec2.InstanceClass.T3, ec2.InstanceSize.SMALL),
      masterUsername: "admin",
      backupRetention: cdk.Duration.days(backupRetention),
      copyTagsToSnapshot: true,
      securityGroups: [ dbSecurityGroup ],
      storageType: rds.StorageType.IO1,
      iops: 2000,
      // enablePerformanceInsights: true, // only works on PG version 10+
      deletionProtection, // false only in development
      multiAz,
      vpc,
    });

Reproduction Steps

Create RDS stack using CDK
Introduce a change (different instance type/size or multiAZ)
CloudFormation throws error Internal Failure

@nija-at I've tried a very minimal configuration for creating RDS using cdk, but I'm getting the same error when trying to introduce a change

    const vpc = ec2.Vpc.fromLookup(this, "vpc", { vpcId: "vpc-1234567890qwert" });

    const dbInstance = new rds.DatabaseInstance(this, "TestingRds", {
      engine: rds.DatabaseInstanceEngine.POSTGRES,
      engineVersion: "11.6",
      instanceClass: ec2.InstanceType.of(ec2.InstanceClass.T3, ec2.InstanceSize.MEDIUM),

nija-at · 2020-03-03T12:25:06Z

I apologize but there's nothing the CDK team can do here. The error is coming from RDS' Frontend that is being invoked by CloudFormation on your behalf.

One possibility is that the CDK turns on DeletionProtection on an instance by default. Modifying any property that would need the instance to be replaced would be forbidden. Maybe this is what's causing the error. Can you try setting up a brand new stack with deletionProtection set to false, followed by the running a similar modification?

Nevertheless, 'Internal Failure' is not an acceptable error message. Continue engaging with AWS support and notify them to reach out to the RDS team.

Internal reference: tt/0308387897

robertd · 2020-03-03T16:54:50Z

@nija-at I understand. I'm going to leave this issue open for the AWS Support team's reference.

robertd · 2020-03-03T18:18:55Z

@nija-at I'm getting same issue w/ DeletionProtection: false as well. I'm baffled why this is happening to be honest. I may try our other AWS account to see if it is account specific issue. I doubt it but at this point I'm checking every minor detail.

robertd · 2020-03-04T01:22:35Z

Hey @nija-at... @MrArnoldPalmer and I were troubleshooting this on Gitter and I believe we found the possible culprit. We've found out that if I create and update stack in default account VPC then everything works fine. I was able to change instance size from t3.small to t3.medium and deletion protection parameter.

Stack ARN:

However, if I create the RDS stack in a shared VPC (imported from different account due to original VPC running low on IPs) then I'm not able to make any changes to that RDS stack (Internal Failure error).

Hopefully this helps AWS team narrow down the issue.

jls-tschanzc · 2020-03-04T12:28:50Z

To add to this, I am also running the Instance in a CDK created VPC:

    const vpc = new Vpc(this, 'TestVPC', {
      natGateways: 1,
      maxAzs: 2,
    });

Same problems (See #6439 ), did not try with default VPC though.

MrArnoldPalmer · 2020-03-04T20:50:41Z

@jls-tschanzc to clarify a bit, is this VPC in the same account that the DB instances is being created in?

I'd encourage you to make a case with AWS support as well if you can since this issues seems to be on the AWS service side and not with CDK.

maiconrocha · 2020-03-04T21:03:44Z

Hi @robertd , thanks for the detailed information in how to reproduce the issue.

I can confirm there is a known issue on Cloudformation with respect to AWS::RDS::DBInstance being created in a VPC shared from a different AWS Account via RAM.

Please follow the link below for updates:
aws-cloudformation/cloudformation-coverage-roadmap#373

Hey @nija-at... @MrArnoldPalmer and I were troubleshooting this on Gitter and I believe we found the possible culprit. We've found out that if I create and update stack in default account VPC then everything works fine. I was able to change instance size from t3.small to t3.medium and deletion protection parameter.

 ✅  TestStack

Stack ARN:
arn:aws:cloudformation:us-west-2:xxxxxxxxxxxxx:stack/TestStack/40b420d0-5db2-11ea-beef-06cac24c53a2
However, if I create the RDS stack in a shared VPC (imported from different account due to original VPC running low on IPs) then I'm not able to make any changes to that RDS stack (Internal Failure error).

Hopefully this helps AWS team narrow down the issue.

Thanks for the update @maiconrocha.

If it's alright, I'm going to go ahead and close this issue since this isn't related to the CDK.

You may continue tracking the issue that @maiconrocha linked above for updates, or with case opened with AWS support.

Let me know if I've missed anything here.

@MrArnoldPalmer
The VPC my Instance is connected to, is in the same account. Created in the same CDK Stack.

@nija-at
So now all issues related to this are either closed or are not related to my issue (as my VPC is in the same account). As I have asked before: On which CFN Repository do you want me to create the issue if nothing can be done about it on the CDK side?

robertd · 2020-03-05T16:09:40Z

@jls-tschanzc I think it would be the best if you can drop a comment w/ what you're experiencing in aws-cloudformation/cloudformation-coverage-roadmap#373. Also it would be beneficial to create an AWS Support ticket in the account you're experiencing issues in linking to both aws-cdk repo and aws-cloudformation-coverage-roadmap issues.

@robertd
Will do so.

I had hoped the CFN team had a way to report issues/bugs without paying for the privilege to do so; Technical Support Tickets are only available for Support Plans higher than "basic".
