AWS Elastic Beanstalk: S3LocationNotInServiceRegionException

Introduction

In AWS Elastic Beanstalk, when setting up your application, you may come across the S3LocationNotInServiceRegionException. This exception occurs when the specified S3 bucket or object location is not in the same region as your Elastic Beanstalk environment.

This article will dive deep into the S3LocationNotInServiceRegionException, its causes, and how to handle it effectively.

Understanding S3LocationNotInServiceRegionException

The S3LocationNotInServiceRegionException is thrown when Elastic Beanstalk detects that the S3 bucket or object specified in your application version does not exist in the same region as your Elastic Beanstalk environment.

This exception usually occurs when you create an S3 bucket or upload your application version to an S3 bucket in a different region and then try to deploy it to an Elastic Beanstalk environment in a different region.

Causes of S3LocationNotInServiceRegionException

The S3LocationNotInServiceRegionException is caused by one or more of the following scenarios:

1. Hosting S3 bucket and environment in different regions: This exception occurs when you create an S3 bucket in one region and try to deploy it to an Elastic Beanstalk environment in another region.

2. Uploading application version to a different region: If you upload your application version to an S3 bucket in a region different from the one where your Elastic Beanstalk environment is located, the exception is thrown.

Handling S3LocationNotInServiceRegionException

To handle the S3LocationNotInServiceRegionException effectively, follow these steps:

1. Verify the S3 bucket region: Ensure that the S3 bucket you are using to store your application version is in the same region as your Elastic Beanstalk environment.

2. Re-upload the application version: If the bucket region is incorrect, remove the existing application version from the S3 bucket and re-upload it to an S3 bucket in the same region as your Elastic Beanstalk environment.

3. Use the correct bucket and region: Double-check that the bucket name and region specified in the Elastic Beanstalk environment configuration match the actual bucket and region.

4. Update the environment configuration: If you discover that the bucket or region is incorrect in the Elastic Beanstalk environment configuration, make the necessary changes and update the environment.

Examples

Let’s take a look at a few examples to understand how the S3LocationNotInServiceRegionException can occur and how to handle it.

Example 1: Specifying an S3 bucket in a different region

AWSElasticBeanstalk client = AWSElasticBeanstalkClientBuilder.defaultClient();

CreateApplicationVersionRequest request = new CreateApplicationVersionRequest()
    .withApplicationName("MyApplication")
    .withVersionLabel("v1.0.0")
    .withSourceBundle(new S3Location("arn:aws:s3:::my-bucket/my-application.zip"));

CreateApplicationVersionResult result = client.createApplicationVersion(request);

In this example, the S3 bucket "my-bucket" is located in a different region than the Elastic Beanstalk environment. To resolve this issue, ensure that the S3 bucket is in the same region as the Elastic Beanstalk environment.

Example 2: Uploading the application version to a different region

$ aws s3 cp my-application.zip s3://us-west-2/my-bucket/

Here, the application version "my-application.zip" is uploaded to the "us-west-2" region, but the Elastic Beanstalk environment is in a different region. To fix this, re-upload the application version to an S3 bucket in the same region as the Elastic Beanstalk environment.

Conclusion

The S3LocationNotInServiceRegionException occurs when there is a mismatch between the S3 bucket or object location and the region of the Elastic Beanstalk environment. By following the guidelines outlined in this article, you will be able to handle this exception effectively and deploy your application without any issues.

For more information, refer to the AWS Elastic Beanstalk documentation, and the AWS SDK for Java documentation.

Remember to always double-check your S3 bucket and region configurations to avoid the S3LocationNotInServiceRegionException.

Happy coding!
