How to Lookup an Amazon Resource using the Amazon Resource Name (ARN)

When working with AWS, one of the most common tasks you’ll encounter as a data scientist or software engineer is looking up specific resources. AWS uses a unique identifier called the Amazon Resource Name (ARN). In this article, we’ll explore ‘How to look up an Amazon resource using the ARN.’

How to Use the ARN to Lookup a Resource

Prerequisites

To perform these tasks, you’ll need:

  • An AWS account
  • AWS CLI installed and configured
  • ARN of the resource you want to look up

Looking Up a Resource

Let’s say we want to look up an S3 bucket. The command would be:

aws s3api get-bucket-acl --bucket arn:aws:s3:::my_bucket

Here we used the get-bucket-acl command to return the Access Control List (ACL) of a bucket, using the ARN of the bucket.

Use Cases of ARN

As a data scientist or software engineer, you may wonder why ARNs are crucial. Here are a few use-cases:

  1. Identifying Resources: When managing multiple resources, ARNs provide a straightforward way to identify them uniquely.

  2. IAM Policies: ARNs are used in IAM policies to specify which resources a policy applies to.

  3. AWS CLI & SDKs: When querying or manipulating resources using AWS CLI and SDKs, you often need to specify the resource by its ARN.

Conclusion

Understanding and using Amazon Resource Names (ARNs) is essential in AWS, as they provide a unique identifier for resources. As a data scientist or software engineer, learning to lookup resources using ARNs can streamline your workflows and increase efficiency.
