Streamline Your Operations: AWS Systems Manager Run Command Enhances Parameter Integration

Amazon Web Services (AWS) has announced a significant enhancement to AWS Systems Manager Run Command, introducing support for interpolating parameters directly into environment variables. This new capability, published on August 5th, 2025, promises to bring greater flexibility, efficiency, and maintainability to how you execute commands across your AWS resources.

Previously, while Run Command offered robust parameter capabilities for command arguments, the ability to dynamically inject these parameters into environment variables within your scripts and commands was more limited. This often necessitated complex workarounds or manual configuration, especially for sensitive information or frequently changing values.

The introduction of parameter interpolation into environment variables directly addresses this challenge. Now, you can leverage the power of Systems Manager Parameter Store or AWS Secrets Manager to securely store and manage values, and seamlessly inject them into the environment where your commands are executed.

What does this mean for you?

This advancement offers several compelling benefits for system administrators, developers, and DevOps teams:

  • Enhanced Security: Instead of hardcoding sensitive information like API keys, database credentials, or passwords directly into your command documents, you can store them securely in AWS Systems Manager Parameter Store or AWS Secrets Manager. Run Command can then retrieve and inject these values as environment variables, reducing the risk of exposure.
  • Increased Flexibility and Dynamic Execution: Imagine scenarios where your commands need to adapt based on specific environments (development, staging, production), instance tags, or even external data sources. With parameter interpolation, you can dynamically set environment variables that influence the behavior of your scripts, enabling more sophisticated and context-aware command execution.
  • Improved Maintainability: Centralizing configuration parameters in Parameter Store or Secrets Manager makes it easier to manage and update them across multiple commands and instances. When a value needs to change, you update it in one place, and all subsequent command executions will automatically pick up the latest version. This drastically reduces the potential for errors and saves valuable time.
  • Simplified Command Documents: By abstracting configuration details into parameters, your Run Command documents become cleaner and more reusable. You can create generic command templates that rely on environment-specific parameters, rather than creating unique documents for each environment.
  • Reduced Script Complexity: The need to manually retrieve and set environment variables within your scripts is often eliminated. Run Command handles the injection process, allowing your scripts to focus on their core logic without being burdened by configuration management tasks.

How it works:

The implementation is designed to be intuitive. Within your Run Command documents, you can now reference parameters using a clear syntax. For example, if you have a parameter named /myapp/database/password stored in Parameter Store, you can reference it within your environment variable definition like this:

json { "schemaVersion": "0.3", "description": "Example command to set environment variable", "parameters": { "databasePassword": { "type": "String", "description": "The database password for the application" } }, "mainSteps": [ { "action": "aws:runShellScript", "name": "runMyScript", "inputs": { "runCommand": [ "echo \"Database username is: $DB_USERNAME\" && echo \"Database password is: $DB_PASSWORD\"" ], "environment": { "DB_USERNAME": "{{ DB_USER }}", "DB_PASSWORD": "{{ databasePassword }}" } } } ] }

In this example, {{ DB_USER }} and {{ databasePassword }} would be placeholders that Run Command resolves using the provided parameters during execution. You can specify these parameters when invoking Run Command via the AWS Management Console, AWS CLI, or SDKs.

Getting Started:

To take advantage of this new feature, ensure your AWS Systems Manager Agent (SSM Agent) is up to date on your managed instances. You can then begin defining your Run Command documents to utilize parameter interpolation for environment variables.

This update signifies AWS’s continued commitment to providing powerful and flexible tools for managing your cloud infrastructure. By simplifying the integration of parameters into your command execution workflows, AWS Systems Manager Run Command empowers you to build more secure, resilient, and efficient operational processes. We encourage you to explore this new capability and discover how it can benefit your AWS environment.
