How to retrieve SSM parameters with Pulumi?

Question

Pulumi · Accepted Answer

Certainly! AWS Systems Manager Parameter Store provides secure, hierarchical storage for configuration data management and secrets management. You can store data such as passwords, database strings, Amazon Machine Image (AMI) IDs, and license codes as parameter values.

Now, let's retrieve a parameter from AWS SSM Parameter Store with Pulumi:

1. Install the required Pulumi AWS package first:

```bash
$ npm install @pulumi/aws
```

Then, let's use the `aws.ssm.Parameter` resource. It facilitates retrieving parameters from the SSM Parameter Store.

```typescript
import * as pulumi from "@pulumi/pulumi";
import * as aws from "@pulumi/aws";

// Retrieve an existing parameter
let ssmParameter = pulumi.output(aws.ssm.getParameter({
    name: "parameterName", // replace with your parameter name
}));

// Export the retrieved parameter value
export const paramValue = ssmParameter.value;
```

This small program does the following:

* Retrieves a parameter from the AWS SSM Parameter Store using the `getParameter` function. The retrieved parameter object is wrapped in a `pulumi.output` to handle the asynchronicity in Pulumi's resource operations.
* Exports the value of the parameter `paramValue`, which makes it available as a stack output.

Remember to replace `"parameterName"` with the actual name of your AWS SSM parameter. You can check the [documentation](https://www.pulumi.com//registry/packages/aws/api-docs/ssm/parameter/) to have broader information about `aws.ssm.Parameter`.
