SecretValue

class aws_cdk.core.SecretValue(value, *, stack_trace=None)

Bases: aws_cdk.core.Intrinsic

Work with secret values in the CDK.

Secret values in the CDK (such as those retrieved from SecretsManager) are represented as regular strings, just like other values that are only available at deployment time.

To help you avoid accidental mistakes which would lead to you putting your secret values directly into a CloudFormation template, constructs that take secret values will not allow you to pass in a literal secret value. They do so by calling Secret.assertSafeSecret().

You can escape the check by calling Secret.plainText(), but doing so is highly discouraged.

Parameters

  • value (Any) –

  • stack_trace (Optional[bool]) – Capture the stack trace of where this token is created. Default: true

Methods

resolve(_context)

Produce the Token’s value at resolution time.

Parameters

_context (IResolveContext) –

Return type

Any

to_json()

Turn this Token into JSON.

Called automatically when JSON.stringify() is called on a Token.

Return type

Any

to_string()

Convert an instance of this Token to a string.

This method will be called implicitly by language runtimes if the object is embedded into a string. We treat it the same as an explicit stringification.

Return type

str

Attributes

creation_stack

The captured stack trace which represents the location in which this token was created.

Return type

List[str]

Static Methods

classmethod cfn_dynamic_reference(ref)

Obtain the secret value through a CloudFormation dynamic reference.

If possible, use SecretValue.ssmSecure or SecretValue.secretsManager directly.

Parameters

ref (CfnDynamicReference) – The dynamic reference to use.

Return type

SecretValue

classmethod cfn_parameter(param)

Obtain the secret value through a CloudFormation parameter.

Generally, this is not a recommended approach. AWS Secrets Manager is the recommended way to reference secrets.

Parameters

param (CfnParameter) – The CloudFormation parameter to use.

Return type

SecretValue

classmethod plain_text(secret)

Construct a literal secret value for use with secret-aware constructs.

Do not use this method for any secrets that you care about.

The only reasonable use case for using this method is when you are testing.

Parameters

secret (str) –

Return type

SecretValue

classmethod secrets_manager(secret_id, *, json_field=None, version_id=None, version_stage=None)

Creates a SecretValue with a value which is dynamically loaded from AWS Secrets Manager.

Parameters

  • secret_id (str) – The ID or ARN of the secret.

  • json_field (Optional[str]) – The key of a JSON field to retrieve. This can only be used if the secret stores a JSON object. Default: - returns all the content stored in the Secrets Manager secret.

  • version_id (Optional[str]) – Specifies the unique identifier of the version of the secret you want to use. Can specify at most one of versionId and versionStage. Default: AWSCURRENT

  • version_stage (Optional[str]) – Specifies the secret version that you want to retrieve by the staging label attached to the version. Can specify at most one of versionId and versionStage. Default: AWSCURRENT

Return type

SecretValue

classmethod ssm_secure(parameter_name, version)

Use a secret value stored from a Systems Manager (SSM) parameter.

Parameters

  • parameter_name (str) – The name of the parameter in the Systems Manager Parameter Store. The parameter name is case-sensitive.

  • version (str) – An integer that specifies the version of the parameter to use. You must specify the exact version. You cannot currently specify that AWS CloudFormation use the latest version of a parameter.

Return type

SecretValue
