AWSConfig

AWSConfig is used to configure an AWS service client instance, such as S3Client or SecretsManagerClient. It effectively allows the user to select a region they wish to interact with, and the AWS credentials they wish to use to authenticate.

AWSConfig is included in the aws.js bundle, which includes all the content of the library. It is also included in the various services clients dedicated bundles such as s3.js and secrets-manager.js.

It takes an options object as its single parameter, with the following properties:

Property	Type	Description
region	string	the AWS region to connect to. As described by Amazon AWS docs
accessKeyID	string	The AWS access key ID credential to use for authentication.
secretAccessKey	string	The AWS secret access credential to use for authentication.
sessionToken (optional)	string	The AWS secret access token to use for authentication.
endpoint (optional)	string	The AWS endpoint. Useful for local testing.

Example

An example showing how you can use k6 to instantiate an AWSConfig object and use it to configure a SecretsManagerClient instance.

import exec from 'k6/execution';

// Note that you AWSConfig is also included in the dedicated service
// client bundles such as `s3.js` and `secrets-manager.js`
import {
  AWSConfig,
  SecretsManagerClient,
} from 'https://jslib.k6.io/aws/0.14.0/aws.js';

const awsConfig = new AWSConfig({
  region: __ENV.AWS_REGION,
  accessKeyId: __ENV.AWS_ACCESS_KEY_ID,
  secretAccessKey: __ENV.AWS_SECRET_ACCESS_KEY,
});

const secretsManager = new SecretsManagerClient(awsConfig);

export default function () {
  // ...
}
