# aws-cdk.aws-ssm — The CDK Construct Library for AWS::SSM

License: permissive · Maintenance: active · Downloads: 169.8K/mo

## What it is and what it does

This package provides Python constructs for AWS CDK v1 that let you define AWS Systems Manager Parameter Store resources in code. It wraps SSM parameter creation and retrieval into reusable CDK components, allowing you to create string and string-list parameters, reference existing parameters by name, and grant read/write permissions to IAM roles. The module integrates with the broader CDK ecosystem through dependencies on aws-cdk.core, aws-cdk.aws-iam, and aws-cdk.aws-kms for encryption support.

The package is part of the AWS CDK v1 library, which is no longer receiving updates. While the repository remains active and the package itself has no known vulnerabilities, AWS officially recommends migrating to CDK v2 for new projects. Existing v1 users can continue to use this package, but should plan a migration path.

Use it for:

- Define SSM string parameters in CDK stacks and grant read access to application roles for configuration management.
- Create SSM string-list parameters to store comma-separated or multi-value configuration data in infrastructure code.
- Reference existing SSM parameters by name in CDK apps to retrieve values for use in other resource definitions.
- Automate parameter creation with validation patterns to enforce naming or format conventions across infrastructure.

## Worth the install?

AI-flagged interpretation of the facts above — verify before relying.

Provides CDK constructs for defining AWS Systems Manager Parameter Store resources (string and list parameters) in infrastructure-as-code, enabling programmatic creation and reference of SSM parameters.

Yes, if you are actively using AWS CDK v1 and need to manage SSM parameters as code. No, if starting a new project—use AWS CDK v2 instead. The package is stable and dependency-light, but its end-of-support status means it will not receive updates for new AWS features or security patches beyond what v1 itself receives.

## Install

pip install aws-cdk-aws-ssm
uv add aws-cdk-aws-ssm
poetry add aws-cdk-aws-ssm

## Installing aws-cdk.aws-ssm

Before you install: Low install friction with a wheel distribution. Maintenance status is active, though the package is part of AWS CDK v1, which reached end-of-support on 2023-06-01; users are advised to migrate to AWS CDK v2.

License in practice: Licensed under Apache-2.0 (permissive), allowing free use, modification, and distribution with minimal restrictions.

Quickstart:

pip install aws-cdk.aws-ssm

import aws_cdk.aws_ssm as ssm

param = ssm.StringParameter(stack, "MyParam",
    string_value="Initial value"
)
param.grant_read(role)

Requires AWS CDK v1 environment; AWS CDK v1 is end-of-support as of 2023-06-01 and migration to v2 is recommended.

Verify before relying:

- Whether existing CDK v1 projects can safely continue using this package or face breaking changes in AWS service updates.
- Performance characteristics when managing large numbers of parameters or parameter versions.
