This module is part of the AWS Cloud Development Kit project.

Installation

Install the module:

$ npm i @aws-cdk/aws-ssm

Import it into your code:

import ssm = require('@aws-cdk/aws-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:

    // Retrieve the latest value of the non-secret parameter
    // with name "/My/String/Parameter".
    const stringValue = ssm.StringParameter.fromStringParameterAttributes(this, 'MyValue', {
      parameterName: '/My/Public/Parameter',
      // 'version' can be specified but is optional.
    }).stringValue;

    // Retrieve a specific version of the secret (SecureString) parameter.
    // 'version' is always required.
    const secretValue = ssm.StringParameter.fromSecureStringParameterAttributes(this, 'MySecureValue', {
      parameterName: '/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).

// Create a new SSM Parameter holding a String
const param = new ssm.StringParameter(stack, 'StringParameter', {
  // description: 'Some user-friendly description',
  // name: 'ParameterName',
  stringValue: 'Initial parameter value',
  // allowedPattern: '.*',
});

// Grant read access to some Role
param.grantRead(role);

// Create a new SSM Parameter holding a StringList
const listParameter = new ssm.StringListParameter(stack, 'StringListParameter', {
  // description: 'Some user-friendly description',
  // name: 'ParameterName',
  stringListValue: ['Initial parameter value A', 'Initial parameter value B'],
  // allowedPattern: '.*',
});

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.
