Question

How to get ARN for s3 Bucket using aws cli

Answer 1

The syntax is : arn:aws:s3:::NAME-OF-YOU-BUCKET.

If the ARN  and the  name of the bucket  is known ,then there is no need to 'get' it from anywhere.

Answer 2

An ARN is a non-opaque, constructible identifier, apparently by design. They aren't at all likely to change the documented rules for the S3 ARN format. The cn-north-1 region is special case, as is GovCloud, because those are completely cordoned off from the global aws partition, not accessible with the same sets of keys. If you're working in multiple partitions, you have to know which partition you're dealing with.

@Priyaj can you elaborate the process??

Answer 3

Was hoping for a way to do this without making any assumptions about the ARN format. Buckets in cn-north-1 region are arn:aws-cn:s3:::BUCKET_NAME and I was hoping to avoid having to "know" how Amazon assigned ARNs in case Amazon were to change the rules
