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 SecureString 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).

new ssm.StringParameter(this, 'Parameter', {
  allowedPattern: '.*',
  description: 'The value Foo',
  parameterName: 'FooParameter',
  stringValue: 'Foo',
  tier: ssm.ParameterTier.ADVANCED,
});

creating SSM parameters

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.
