# Example may have issues. See https://github.com/aws/jsii/issues/826
import aws_cdk.aws_ssm as ssm

Using existing SSM Parameters in your CDK app

You can reference existing SSM Parameter Store values that you want to use in your CDK app by using ssm.ParameterStoreString:

# Example may have issues. See https://github.com/aws/jsii/issues/826
# Retrieve the latest value of the non-secret parameter
# with name "/My/String/Parameter".
string_value = ssm.StringParameter.from_string_parameter_attributes(self, "MyValue",
    parameter_name="/My/Public/Parameter"
).string_value

# Retrieve a specific version of the secret (SecureString) parameter.
# 'version' is always required.
secret_value = ssm.StringParameter.from_secure_string_parameter_attributes(self, "MySecureValue",
    parameter_name="/My/Secret/Parameter",
    version=5
)

Creating new SSM Parameters in your CDK app

You can create either ssm.StringParameter or ssm.StringListParameters in a CDK app. These are public (not secret) values. Parameters of type SecretString cannot be created directly from a CDK application; if you want to provision secrets automatically, use Secrets Manager Secrets (see the @aws-cdk/aws-secretsmanager package).

# Example may have issues. See https://github.com/aws/jsii/issues/826
# Create a new SSM Parameter holding a String
param = ssm.StringParameter(stack, "StringParameter",
    # description: 'Some user-friendly description',
    # name: 'ParameterName',
    string_value="Initial parameter value"
)

# Grant read access to some Role
param.grant_read(role)

# Create a new SSM Parameter holding a StringList
list_parameter = ssm.StringListParameter(stack, "StringListParameter",
    # description: 'Some user-friendly description',
    # name: 'ParameterName',
    string_list_value=["Initial parameter value A", "Initial parameter value B"]
)

When specifying an allowedPattern, the values provided as string literals are validated against the pattern and an exception is raised if a value provided does not comply.
