How to Configure STSAssumeRoleSessionCredentialsProvider in Spring Cloud Stream Kinesis Binder

When working with Amazon Kinesis in a Spring Cloud application, you might face challenges related to accessing Kinesis data streams across different AWS accounts. This guide addresses a common issue: how to configure the STSAssumeRoleSessionCredentialsProvider in spring-cloud-stream-binder-kinesis, particularly when your Kinesis data streams are hosted in one AWS account and your application is running in a different one.

The Challenge

If you've been using spring-cloud-stream-binder-kinesis, you probably relied on the default ContextCredentialsAutoConfiguration for local development, which works well in simpler setups. However, complications arise when:

Your Kinesis data stream resides in AWS Account 1.

Your Spring Cloud application is running in AWS Account 2.

In scenarios like this, you need to transition from using default credentials to an STSAssumeRoleSessionCredentialsProvider that allows your application to assume a role in Account 1 to access its Kinesis streams.

The Solution

Configuring the STSAssumeRoleSessionCredentialsProvider in your Spring application involves a few straightforward steps. Let's break it down:

1. Understanding KinesisBinderConfiguration

The KinesisBinderConfiguration in Spring depends on auto-configuration provided by Spring Cloud AWS. This setup typically creates and exposes an AWSCredentialsProvider bean. If you haven't defined any specific credentials provider, the default setup uses the standard context credentials.

2. Defining the Credentials Provider

To override the default configuration with your STSAssumeRoleSessionCredentialsProvider, you need to define it explicitly in your Spring configuration. Here’s how:

Step-by-Step Configuration

Import Required Libraries: Ensure you have the required dependencies added to your pom.xml or build.gradle to use both AWS SDK and Spring Cloud AWS.

Create Configuration Class:
Create a new Spring configuration class or modify an existing one. Here's an example:

Replace ACCOUNT_ID and ROLE_NAME with your actual AWS account ID and the name of the role you want to assume.

The withRoleSessionName can be any string that helps you identify the session.

Specify the Bean Name: Make sure that the bean's name matches credentialsProvider so it gets picked up correctly by Spring Cloud Stream Kinesis Binder.

3. Testing Your Configuration

After setting up your configuration, you can run your Spring Cloud application. If configured correctly, your application will assume the specified role in Account 1 and gain access to the Kinesis data streams.

Conclusion

Configuring the STSAssumeRoleSessionCredentialsProvider for Spring Cloud Stream Binder Kinesis allows your AWS resources to communicate securely across different accounts. By following the steps outlined in this guide, you can effectively manage access between your applications and AWS services without compromising security.
