I have tried both s3cmd
:
$ s3cmd -r -f -v del s3://my-versioned-bucket/
And the AWS CLI:
$ aws s3 rm s3://my-v
If you have to delete/empty large S3 buckets, it becomes quite inefficient (and expensive) to delete every single object and version. It's often more convenient to let AWS expire all objects and versions.
aws s3api put-bucket-lifecycle-configuration \
--lifecycle-configuration '{"Rules":[{
"ID":"empty-bucket",
"Status":"Enabled",
"Prefix":"",
"Expiration":{"Days":1},
"NoncurrentVersionExpiration":{"NoncurrentDays":1}
}]}' \
--bucket YOUR-BUCKET
Then you just have to wait 1 day and the bucket can be deleted with:
aws s3api delete-bucket --bucket YOUR-BUCKET
