AWS SDK V2: Setting Credentials from Variables

This article resolves the query of how to use credentials from variables when working with AWS SDK version 2 for Go.

Question:

A developer seeks to create a new client and use the IAM service with credentials stored as variables. However, the SDK v2 no longer uses the Session approach, unlike the previous version, leaving them uncertain about how to pass these credentials effectively.

Solution:

To address this, the StaticCredentialsProvider can be utilized, as outlined in the AWS SDK for Go V2 documentation's "Static Credentials" section:

<code class="go">cfg, err := config.LoadDefaultConfig(ctx, config.WithCredentialsProvider(credentials.NewStaticCredentialsProvider("AKID", "SECRET_KEY", "TOKEN")))
if err != nil {
    // Handle error
}</code>

In this example, the AKID, SECRET_KEY, and TOKEN values represent the credentials to be used by the client. This approach allows multiple users to access the application concurrently without resorting to ENV files.
