AWS::SecretsManager::RotationSchedule HostedRotationLambda - AWS CloudFormation
SyntaxProperties

AWS::SecretsManager::RotationSchedule HostedRotationLambda

Creates a new Lambda rotation function based on one of the Secrets Manager rotation function templates.

You must specify Transform: AWS::SecretsManager-2024-09-16 at the beginning of the CloudFormation template.

For Amazon RDS master user credentials, see AWS::RDS::DBCluster MasterUserSecret.

For Amazon Redshift admin user credentials, see AWS::Redshift::Cluster.

Syntax

To declare this entity in your AWS CloudFormation template, use the following syntax:

JSON

{
  "ExcludeCharacters" : String,
  "KmsKeyArn" : String,
  "MasterSecretArn" : String,
  "MasterSecretKmsKeyArn" : String,
  "RotationLambdaName" : String,
  "RotationType" : String,
  "Runtime" : String,
  "SuperuserSecretArn" : String,
  "SuperuserSecretKmsKeyArn" : String,
  "VpcSecurityGroupIds" : String,
  "VpcSubnetIds" : String
}

Properties

ExcludeCharacters

A string of the characters that you don't want in the password.

Required: No

Type: String

Update requires: No interruption

KmsKeyArn

The ARN of the KMS key that Secrets Manager uses to encrypt the secret. If you don't specify this value, then Secrets Manager uses the key aws/secretsmanager. If aws/secretsmanager doesn't yet exist, then Secrets Manager creates it for you automatically the first time it encrypts the secret value.

Required: No

Type: String

Update requires: No interruption

MasterSecretArn

The ARN of the secret that contains superuser credentials, if you use the Alternating users rotation strategy. CloudFormation grants the execution role for the Lambda rotation function GetSecretValue permission to the secret in this property. For more information, see Lambda rotation function execution role permissions for Secrets Manager.

You must create the superuser secret before you can set this property.

You must also include the superuser secret ARN as a key in the JSON of the rotating secret so that the Lambda rotation function can find it. CloudFormation does not hardcode secret ARNs in the Lambda rotation function, so you can use the function to rotate multiple secrets. For more information, see JSON structure of Secrets Manager secrets.

You can specify MasterSecretArn or SuperuserSecretArn but not both. They represent the same superuser secret.

Required: No

Type: String

Update requires: No interruption

MasterSecretKmsKeyArn

The ARN of the KMS key that Secrets Manager used to encrypt the superuser secret, if you use the alternating users strategy and the superuser secret is encrypted with a customer managed key. You don't need to specify this property if the superuser secret is encrypted using the key aws/secretsmanager. CloudFormation grants the execution role for the Lambda rotation function Decrypt, DescribeKey, and GenerateDataKey permission to the key in this property. For more information, see Lambda rotation function execution role permissions for Secrets Manager.

You can specify MasterSecretKmsKeyArn or SuperuserSecretKmsKeyArn but not both. They represent the same superuser secret KMS key.

Required: No

Type: String

Update requires: No interruption

RotationLambdaName

The name of the Lambda rotation function.

Required: No

Type: String

Update requires: No interruption

RotationType

The rotation template to base the rotation function on, one of the following:

Required: Yes

Type: String

Update requires: No interruption

Runtime
Important

Do not set this value if you are using Transform: AWS::SecretsManager-2024-09-16. Over time, the updated rotation lambda artifacts vended by AWS may not be compatible with the code or shared object files defined in the rotation function deployment package.

Only define the Runtime key if:

  1. You are using Transform: AWS::SecretsManager-2020-07-23.

  2. The code or shared object files defined in the rotation function deployment package are incompatible with Python 3.9.

The Python Runtime version for with the rotation function. By default, CloudFormation deploys Python 3.9 binaries for the rotation function. To use a different version of Python, you must do the following two steps:

  1. Deploy the matching version Python binaries with your rotation function.

  2. Set the version number in this field. For example, for Python 3.7, enter python3.7.

If you only do one of the steps, your rotation function will be incompatible with the binaries. For more information, see Why did my Lambda rotation function fail with a "pg module not found" error.

Required: No

Type: String

Update requires: No interruption

SuperuserSecretArn

The ARN of the secret that contains superuser credentials, if you use the Alternating users rotation strategy. CloudFormation grants the execution role for the Lambda rotation function GetSecretValue permission to the secret in this property. For more information, see Lambda rotation function execution role permissions for Secrets Manager.

You must create the superuser secret before you can set this property.

You must also include the superuser secret ARN as a key in the JSON of the rotating secret so that the Lambda rotation function can find it. CloudFormation does not hardcode secret ARNs in the Lambda rotation function, so you can use the function to rotate multiple secrets. For more information, see JSON structure of Secrets Manager secrets.

You can specify MasterSecretArn or SuperuserSecretArn but not both. They represent the same superuser secret.

Required: No

Type: String

Update requires: No interruption

SuperuserSecretKmsKeyArn

The ARN of the KMS key that Secrets Manager used to encrypt the superuser secret, if you use the alternating users strategy and the superuser secret is encrypted with a customer managed key. You don't need to specify this property if the superuser secret is encrypted using the key aws/secretsmanager. CloudFormation grants the execution role for the Lambda rotation function Decrypt, DescribeKey, and GenerateDataKey permission to the key in this property. For more information, see Lambda rotation function execution role permissions for Secrets Manager.

You can specify MasterSecretKmsKeyArn or SuperuserSecretKmsKeyArn but not both. They represent the same superuser secret KMS key.

Required: No

Type: String

Update requires: No interruption

VpcSecurityGroupIds

A comma-separated list of security group IDs applied to the target database.

The template applies the same security groups as on the Lambda rotation function that is created as part of this stack.

Required: No

Type: String

Update requires: No interruption

VpcSubnetIds

A comma separated list of VPC subnet IDs of the target database network. The Lambda rotation function is in the same subnet group.

Required: No

Type: String

Update requires: No interruption
