AWS::SecretsManager::RotationSchedule

Sets the rotation schedule and Lambda rotation function for a secret. For more information, see How rotation works.

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

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

For the rotation function, you have two options:

For database secrets, if you define both the secret and the database or service in the AWS CloudFormation template, then you need to define the AWS::SecretsManager::SecretTargetAttachment resource to populate the secret with the connection details of the database or service before you attempt to configure rotation.

For a single secret, you can only define one rotation schedule with it.

Syntax

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

JSON

{
  "Type" : "AWS::SecretsManager::RotationSchedule",
  "Properties" : {
      "HostedRotationLambda" : HostedRotationLambda,
      "RotateImmediatelyOnUpdate" : Boolean,
      "RotationLambdaARN" : String,
      "RotationRules" : RotationRules,
      "SecretId" : String
    }
}

YAML

Type: AWS::SecretsManager::RotationSchedule
Properties:
  HostedRotationLambda: 
    HostedRotationLambda
  RotateImmediatelyOnUpdate: Boolean
  RotationLambdaARN: String
  RotationRules: 
    RotationRules
  SecretId: String

Properties

HostedRotationLambda

Creates a new Lambda rotation function based on one of the Secrets Manager rotation function templates. To use a rotation function that already exists, specify RotationLambdaARN instead.

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

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

Required: No

Type: HostedRotationLambda

Update requires: No interruption

RotateImmediatelyOnUpdate

Specifies whether to rotate the secret immediately or wait until the next scheduled rotation window. The rotation schedule is defined in RotationRules.

If you don't immediately rotate the secret, Secrets Manager tests the rotation configuration by running the testSecret step of the Lambda rotation function. The test creates an AWSPENDING version of the secret and then removes it.

If you don't specify this value, then by default, Secrets Manager rotates the secret immediately.

Rotation is an asynchronous process. For more information, see How rotation works.

Required: No

Type: Boolean

Update requires: No interruption

RotationLambdaARN

The ARN of an existing Lambda rotation function. To specify a rotation function that is also defined in this template, use the Ref function.

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

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

To create a new rotation function based on one of the Secrets Manager rotation function templates, specify HostedRotationLambda instead.

Required: No

Type: String

Update requires: No interruption

RotationRules

A structure that defines the rotation configuration for this secret.

Required: No

Type: RotationRules

Update requires: No interruption

SecretId

The ARN or name of the secret to rotate. This is unique for each rotation schedule definition.

To reference a secret also created in this template, use the Ref function with the secret's logical ID.

Required: Yes

Type: String

Update requires: Replacement

Return values

Ref

When you pass the logical ID of an AWS::SecretsManager::RotationSchedule resource to the intrinsic Ref function, the function returns the ARN of the secret being configured, such as:

arn:aws:secretsmanager: us-west-2:123456789012:secret:my-path/my-secret-name-1a2b3c

You can use the ARN to reference a secret you create in one part of the stack template from within the definition of another resource later, in the same template. You typically do this when you define the AWS::SecretsManager::SecretTargetAttachment resource type.

For more information about using the Ref function, see Ref.

Fn::GetAtt

The Fn::GetAtt intrinsic function returns a value for a specified attribute of this type. The following are the available attributes and sample return values.

For more information about using the Fn::GetAtt intrinsic function, see Fn::GetAtt.

Examples

Automatic rotation with a cron expression

The following example rotates a secret every day between 1:00 AM and 3:00 AM UTC.

JSON

"MySecretRotationSchedule": {
  "Type": "AWS::SecretsManager::RotationSchedule",
  "DependsOn": "MyRotationLambda",
  "Properties": {
    "SecretId": {"Ref": "MySecret"},
    "RotationLambdaARN": {"Fn::GetAtt": "MyRotationLambda.Arn"},
    "RotationRules": {
      "Duration": "2h",
      "ScheduleExpression": "cron(0 1 * * ? *)"
    }
  }
}

YAML

MySecretRotationSchedule:
  Type: AWS::SecretsManager::RotationSchedule
  DependsOn: MyRotationLambda 
  Properties:
    SecretId: !Ref MySecret
    RotationLambdaARN: !GetAtt MyRotationLambda.Arn
    RotationRules:
      Duration: 2h
      ScheduleExpression: 'cron(0 1 * * ? *)'

Automatic rotation with a rate expression

The following example rotates a secret between midnight and 6:00 AM UTC every 10 days.

JSON

"MySecretRotationSchedule": {
  "Type": "AWS::SecretsManager::RotationSchedule",
  "DependsOn": "MyRotationLambda",
  "Properties": {
  "SecretId": {"Ref": "MySecret"},
    "RotationLambdaARN": {"Fn::GetAtt": "MyRotationLambda.Arn"},
    "RotationRules": {
      "Duration": "6h",
      "ScheduleExpression": "rate(10 days)"
      }
    }
  }

YAML

MySecretRotationSchedule:
  Type: AWS::SecretsManager::RotationSchedule
  DependsOn: MyRotationLambda 
  Properties:
    SecretId: !Ref MySecret
    RotationLambdaARN: !GetAtt MyRotationLambda.Arn
    RotationRules:
      Duration: 6h
      ScheduleExpression: 'rate(10 days)'

DocumentDB secret rotation example

The following example creates a DocumentDB database instance and a secret with credentials. The secret is configured to rotate on the first Sunday of every month between 4:00 AM and 6:00 AM UTC.
