Passing Credentials from Variables to AWS SDK Version 2
This inquiry echoes a previous question regarding using AWS SDK with credentials from variables. However, in this case, SDK version 2 is utilized, which eliminates the Session feature.
To establish a new client with credentials obtained from variables for accessing the IAM service, consider the following function:
<code class="go">func getIAMClient(ctx context.Context) (*iam.Client, error) { cfg, err := config.LoadDefaultConfig(ctx, config.WithRegion("no-region")) if err != nil { return nil, errors.Wrap(err) } cfg.HTTPClient, err = getHTTPClient(ctx) if err != nil { return nil, err } return iam.NewFromConfig(cfg), nil }</code>
Since multiple users may employ the application simultaneously, utilizing ENV files is impractical. However, documentation explaining how to pass these credentials to a client may not be readily available.
Solution: Static Credentials Provider
To resolve this issue, the StaticCredentialsProvider can be utilized, as outlined in the "Static Credentials" section of the AWS SDK for Go V2 documentation:
<code class="go">cfg, err := config.LoadDefaultConfig(ctx, config.WithCredentialsProvider(credentials.NewStaticCredentialsProvider("AKID", "SECRET_KEY", "TOKEN")))</code>
By incorporating this modification, credentials may be passed from variables to the SDK, enabling the retrieval and use of IAM services.
