Configuring the parameters property for a SSM Association in AWS CDK

I am working on utilizing the AWS Systems Manager State Manager to automate shutting down an RDS instance at 9PM using a cron job. Currently, I am constructing the CloudFormation template with the help of AWS CDK.

While going through the AWS CDK documentation for the CfnAssociation construct, I came across the parameters property which has a type of any. I am looking for a sample on how to effectively utilize this property.

I need assistance in properly adding the parameter AutomationAssumeRole by following this code snippet. The AutomationAssumeRole requires the ARN for the role, such as 

arn:aws:iam::12345678999:role/StopStartRebootRDS
.

// Setting up the State Manager association to shut down an RDS instance.
new ssm.CfnAssociation(this, 'StopRdsInstanceAssociation', {
  name: 'AWS-StopRdsInstance',
  associationName: 'StopRdsInstance',
  documentVersion: '$DEFAULT',
  instanceId: dbInstance.instanceIdentifier,
  scheduleExpression: '0 00 21 ? * * *',
  parameters: {}, // How should this be configured?
});

Your advice would be greatly appreciated.

My Attempts

Initially, I attempted to create an SSM parameter and store the Role ARN inside it. However, I realized that this approach was incorrect. I am unsure about the correct way to set this up. The error message resulting from this configuration is provided below.

const automationAssumeRole = new ssm.CfnParameter(this, 'RdsParameter', {
  type: 'String',
  value: role.roleArn,
});

// Setting up the State Manager association to shut down an RDS instance.
new ssm.CfnAssociation(this, 'StopRdsInstanceAssociation', {
  name: 'AWS-StopRdsInstance',
  associationName: 'StopRdsInstance',
  documentVersion: '$DEFAULT',
  instanceId: dbInstance.instanceIdentifier,
  scheduleExpression: '0 00 21 ? * * *',
  parameters: {
    automationAssumeRole,
  },
});

Error: Resolution error: Resolution error: Trying to resolve() a Construct at /Resources/${Token[InfrastructureDev.RdsStack.StopRdsInstanceAssociation.LogicalID.762]}/Properties/parameters/automationAssumeRole/node..

Answer №1

Directly pass the ARN of the role. The parameter key names must be in Pascal Case.

Create a new association for stopping RDS instances:

For more information, check out this AWS blog post: Schedule Amazon RDS stop and start using AWS Systems Manager. It explains how to use instance id and role effectively.

Answer №2

There is a current discussion about this specific problem on Github in an issue. After examining a suggested workaround, I have decided to utilize an alternative method to implement the changes. The solution that worked for me involves:

// Implementing the State Manager association responsible for shutting down an RDS instance.
const association = new ssm.CfnAssociation(this, 'StopRdsInstanceAssociation', {
  name: 'AWS-StopRdsInstance',
  associationName: 'StopRdsInstance',
  scheduleExpression: 'cron(0 00 2 ? * * *)',
});

// Using a different approach to modify parameters. Reference: https://github.com/aws/aws-cdk/issues/4057
association.addPropertyOverride('Parameters.InstanceId', [dbInstance.instanceIdentifier]);
association.addPropertyOverride('Parameters.AutomationAssumeRole', [role.roleArn]);

Update

I want to preserve this information for historical reference, but I have found @fedonev's solution to be effective for my situation. No need for an alternative method.
