CfnSecret

class aws_cdk.aws_secretsmanager.CfnSecret(scope, id, *, description=None, generate_secret_string=None, kms_key_id=None, name=None, replica_regions=None, secret_string=None, tags=None)

Bases: CfnResource

A CloudFormation AWS::SecretsManager::Secret.

Creates a new secret. A secret can be a password, a set of credentials such as a user name and password, an OAuth token, or other secret information that you store in an encrypted form in Secrets Manager.

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

To retrieve a secret in a CloudFormation template, use a dynamic reference . For more information, see Retrieve a secret in an AWS CloudFormation resource .

A common scenario is to first create a secret with GenerateSecretString , which generates a password, and then use a dynamic reference to retrieve the username and password from the secret to use as credentials for a new database. Follow these steps, as shown in the examples below:

  • Define the secret without referencing the service or database. You can’t reference the service or database because it doesn’t exist yet. The secret must contain a username and password.

  • Next, define the service or database. Include the reference to the secret to use stored credentials to define the database admin user and password.

  • Finally, define a SecretTargetAttachment resource type to finish configuring the secret with the required database engine type and the connection details of the service or database. The rotation function requires the details, if you attach one later by defining a AWS::SecretsManager::RotationSchedule resource type.

For information about creating a secret in the console, see Create a secret . For information about creating a secret using the CLI or SDK, see CreateSecret .

For information about retrieving a secret in code, see Retrieve secrets from Secrets Manager . .. epigraph:

Do not create a dynamic reference using a backslash ``(\)`` as the final value. AWS CloudFormation cannot resolve those references, which causes a resource failure.

Create a new AWS::SecretsManager::Secret.

Parameters:
  • scope (Construct) –

    • scope in which this resource is defined.

  • id (str) –

    • scoped id of the resource.

  • description (Optional[str]) – The description of the secret.

  • generate_secret_string (Union[IResolvable, GenerateSecretStringProperty, Dict[str, Any], None]) – A structure that specifies how to generate a password to encrypt and store in the secret. To include a specific string in the secret, use SecretString instead. If you omit both GenerateSecretString and SecretString , you create an empty secret. When you make a change to this property, a new secret version is created. We recommend that you specify the maximum length and include every character type that the system you are generating a password for can support.

  • kms_key_id (Optional[str]) – The ARN, key ID, or alias of the AWS KMS key that Secrets Manager uses to encrypt the secret value in the secret. An alias is always prefixed by alias/ , for example alias/aws/secretsmanager . For more information, see About aliases . To use a AWS KMS key in a different account, use the key ARN or the alias ARN. If you don’t specify this value, then Secrets Manager uses the key aws/secretsmanager . If that key doesn’t yet exist, then Secrets Manager creates it for you automatically the first time it encrypts the secret value. If the secret is in a different AWS account from the credentials calling the API, then you can’t use aws/secretsmanager to encrypt the secret, and you must create and use a customer managed AWS KMS key.

  • name (Optional[str]) – The name of the new secret. The secret name can contain ASCII letters, numbers, and the following characters: /_+=.@- Do not end your secret name with a hyphen followed by six characters. If you do so, you risk confusion and unexpected results when searching for a secret by partial ARN. Secrets Manager automatically adds a hyphen and six random characters after the secret name at the end of the ARN.

  • replica_regions (Union[IResolvable, Sequence[Union[IResolvable, ReplicaRegionProperty, Dict[str, Any]]], None]) – A custom type that specifies a Region and the KmsKeyId for a replica secret.

  • secret_string (Optional[str]) – The text to encrypt and store in the secret. We recommend you use a JSON structure of key/value pairs for your secret value. To generate a random password, use GenerateSecretString instead. If you omit both GenerateSecretString and SecretString , you create an empty secret. When you make a change to this property, a new secret version is created.

  • tags (Optional[Sequence[Union[CfnTag, Dict[str, Any]]]]) – A list of tags to attach to the secret. Each tag is a key and value pair of strings in a JSON text string, for example: [{"Key":"CostCenter","Value":"12345"},{"Key":"environment","Value":"production"}] Secrets Manager tag key names are case sensitive. A tag with the key “ABC” is a different tag from one with key “abc”. If you check tags in permissions policies as part of your security strategy, then adding or removing a tag can change permissions. If the completion of this operation would result in you losing your permissions for this secret, then Secrets Manager blocks the operation and returns an Access Denied error. For more information, see Control access to secrets using tags and Limit access to identities with tags that match secrets’ tags . For information about how to format a JSON parameter for the various command line tool environments, see Using JSON for Parameters . If your command-line tool or SDK requires quotation marks around the parameter, you should use single quotes to avoid confusion with the double quotes required in the JSON text. The following restrictions apply to tags: - Maximum number of tags per secret: 50 - Maximum key length: 127 Unicode characters in UTF-8 - Maximum value length: 255 Unicode characters in UTF-8 - Tag keys and values are case sensitive. - Do not use the aws: prefix in your tag names or values because AWS reserves it for AWS use. You can’t edit or delete tag names or values with this prefix. Tags with this prefix do not count against your tags per secret limit. - If you use your tagging schema across multiple services and resources, other services might have restrictions on allowed characters. Generally allowed characters: letters, spaces, and numbers representable in UTF-8, plus the following special characters: + - = . _ : / @.

Methods

add_deletion_override(path)

Syntactic sugar for addOverride(path, undefined).

Parameters:

path (str) – The path of the value to delete.

Return type:

None

add_depends_on(target)

Indicates that this resource depends on another resource and cannot be provisioned unless the other resource has been successfully provisioned.

This can be used for resources across stacks (or nested stack) boundaries and the dependency will automatically be transferred to the relevant scope.

Parameters:

target (CfnResource) –

Return type:

None

add_metadata(key, value)

Add a value to the CloudFormation Resource Metadata.

Parameters:
  • key (str) –

  • value (Any) –

See:

Return type:

None

https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/metadata-section-structure.html

Note that this is a different set of metadata from CDK node metadata; this metadata ends up in the stack template under the resource, whereas CDK node metadata ends up in the Cloud Assembly.

add_override(path, value)

Adds an override to the synthesized CloudFormation resource.

To add a property override, either use addPropertyOverride or prefix path with “Properties.” (i.e. Properties.TopicName).

If the override is nested, separate each nested level using a dot (.) in the path parameter. If there is an array as part of the nesting, specify the index in the path.

To include a literal . in the property name, prefix with a \. In most programming languages you will need to write this as "\\." because the \ itself will need to be escaped.

For example:

cfn_resource.add_override("Properties.GlobalSecondaryIndexes.0.Projection.NonKeyAttributes", ["myattribute"])
cfn_resource.add_override("Properties.GlobalSecondaryIndexes.1.ProjectionType", "INCLUDE")

would add the overrides Example:

"Properties": {
   "GlobalSecondaryIndexes": [
     {
       "Projection": {
         "NonKeyAttributes": [ "myattribute" ]
         ...
       }
       ...
     },
     {
       "ProjectionType": "INCLUDE"
       ...
     },
   ]
   ...
}

The value argument to addOverride will not be processed or translated in any way. Pass raw JSON values in here with the correct capitalization for CloudFormation. If you pass CDK classes or structs, they will be rendered with lowercased key names, and CloudFormation will reject the template.

Parameters:
  • path (str) –

    • The path of the property, you can use dot notation to override values in complex types. Any intermdediate keys will be created as needed.

  • value (Any) –

    • The value. Could be primitive or complex.

Return type:

None

add_property_deletion_override(property_path)

Adds an override that deletes the value of a property from the resource definition.

Parameters:

property_path (str) – The path to the property.

Return type:

None

add_property_override(property_path, value)

Adds an override to a resource property.

Syntactic sugar for addOverride("Properties.<...>", value).

Parameters:
  • property_path (str) – The path of the property.

  • value (Any) – The value.

Return type:

None

apply_removal_policy(policy=None, *, apply_to_update_replace_policy=None, default=None)

Sets the deletion policy of the resource based on the removal policy specified.

The Removal Policy controls what happens to this resource when it stops being managed by CloudFormation, either because you’ve removed it from the CDK application or because you’ve made a change that requires the resource to be replaced.

The resource can be deleted (RemovalPolicy.DESTROY), or left in your AWS account for data recovery and cleanup later (RemovalPolicy.RETAIN).

Parameters:
  • policy (Optional[RemovalPolicy]) –

  • apply_to_update_replace_policy (Optional[bool]) – Apply the same deletion policy to the resource’s “UpdateReplacePolicy”. Default: true

  • default (Optional[RemovalPolicy]) – The default policy to apply in case the removal policy is not defined. Default: - Default value is resource specific. To determine the default value for a resoure, please consult that specific resource’s documentation.

Return type:

None

get_att(attribute_name)

Returns a token for an runtime attribute of this resource.

Ideally, use generated attribute accessors (e.g. resource.arn), but this can be used for future compatibility in case there is no generated attribute.

Parameters:

attribute_name (str) – The name of the attribute.

Return type:

Reference

get_metadata(key)

Retrieve a value value from the CloudFormation Resource Metadata.

Parameters:

key (str) –

See:

Return type:

Any

https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/metadata-section-structure.html

Note that this is a different set of metadata from CDK node metadata; this metadata ends up in the stack template under the resource, whereas CDK node metadata ends up in the Cloud Assembly.

Parameters:

inspector (TreeInspector) –

  • tree inspector to collect and process attributes.

Return type:

None

override_logical_id(new_logical_id)

Return type:

None

to_string()

Returns a string representation of this construct.

Return type:

str

Returns:

a string representation of this resource

generate_secret_string

A structure that specifies how to generate a password to encrypt and store in the secret.

To include a specific string in the secret, use SecretString instead. If you omit both GenerateSecretString and SecretString , you create an empty secret. When you make a change to this property, a new secret version is created.

We recommend that you specify the maximum length and include every character type that the system you are generating a password for can support.

Link:

http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-secretsmanager-secret.html#cfn-secretsmanager-secret-generatesecretstring

kms_key_id

The ARN, key ID, or alias of the AWS KMS key that Secrets Manager uses to encrypt the secret value in the secret.

An alias is always prefixed by alias/ , for example alias/aws/secretsmanager . For more information, see About aliases .

To use a AWS KMS key in a different account, use the key ARN or the alias ARN.

If you don’t specify this value, then Secrets Manager uses the key aws/secretsmanager . If that key doesn’t yet exist, then Secrets Manager creates it for you automatically the first time it encrypts the secret value.

If the secret is in a different AWS account from the credentials calling the API, then you can’t use aws/secretsmanager to encrypt the secret, and you must create and use a customer managed AWS KMS key.

Link:

http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-secretsmanager-secret.html#cfn-secretsmanager-secret-kmskeyid

logical_id

The logical ID for this CloudFormation stack element.

The logical ID of the element is calculated from the path of the resource node in the construct tree.

To override this value, use overrideLogicalId(newLogicalId).

Returns:

the logical ID as a stringified token. This value will only get resolved during synthesis.

name

The name of the new secret.

The secret name can contain ASCII letters, numbers, and the following characters: /_+=.@-

Do not end your secret name with a hyphen followed by six characters. If you do so, you risk confusion and unexpected results when searching for a secret by partial ARN. Secrets Manager automatically adds a hyphen and six random characters after the secret name at the end of the ARN.

Link:

http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-secretsmanager-secret.html#cfn-secretsmanager-secret-name

node

The construct tree node associated with this construct.

ref

Return a string that will be resolved to a CloudFormation { Ref } for this element.

If, by any chance, the intrinsic reference of a resource is not a string, you could coerce it to an IResolvable through Lazy.any({ produce: resource.ref }).

replica_regions

A custom type that specifies a Region and the KmsKeyId for a replica secret.

Link:

http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-secretsmanager-secret.html#cfn-secretsmanager-secret-replicaregions

secret_string

The text to encrypt and store in the secret.

We recommend you use a JSON structure of key/value pairs for your secret value. To generate a random password, use GenerateSecretString instead. If you omit both GenerateSecretString and SecretString , you create an empty secret. When you make a change to this property, a new secret version is created.

Link:

http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-secretsmanager-secret.html#cfn-secretsmanager-secret-secretstring

stack

The stack in which this element is defined.

CfnElements must be defined within a stack scope (directly or indirectly).

tags

A list of tags to attach to the secret.

Each tag is a key and value pair of strings in a JSON text string, for example:

[{"Key":"CostCenter","Value":"12345"},{"Key":"environment","Value":"production"}]

Secrets Manager tag key names are case sensitive. A tag with the key “ABC” is a different tag from one with key “abc”.

If you check tags in permissions policies as part of your security strategy, then adding or removing a tag can change permissions. If the completion of this operation would result in you losing your permissions for this secret, then Secrets Manager blocks the operation and returns an Access Denied error.
