You cannot rename an S3 bucket directly, but there are various reasons that you might desperately need to make such a change. For instance, if you created bucket "bucket.example.com" years ago with dots, you might need to rename it to "bucket-example-com" to eliminate the dots so that the SSL validates appropriately when accessed as a subdomain of s3.amazonaws.com. Such access methods do not appear to be necessary versus referencing the bucket as the path prefix, but it has been standardized in some software like ec2-upload-bundle.
- Create the new bucket "new-bucket" (can be done online)
Copy all objects from "old.bucket" to "new-bucket" from the command-line (ideally from EC2):
aws s3 sync s3://old.bucket s3://new-bucket
- Update your system to point at new-bucket
Empty the old bucket using an appropriate strategy:
- If you your objects are in folders, you can empty the bucket by deleting the root objects and folders through the online management console.
- If you have significant amounts of content in the bucket, you can set a lifecycle rule to delete content after 0 days. It may take a day for the bucket to get emptied, but it is easy if you are patient. (can be done online)
If you're in a hurry and did not use folders for easy manual deletion, you can use a quick script like:
aws s3 ls s3://old.bucket | sed 's/.* //' | while read f; do aws s3 rm "s3://old.bucket/$f"; done
- Delete the old bucket (can be done online)
