Boto3/S3: Renaming an object using copy_object


I found another solution

s3 = boto3.resource('s3')s3.Object('my_bucket','new_file_key').copy_from(CopySource='my_bucket/old_file_key')s3.Object('my_bucket','old_file_key').delete()


You cannot rename objects in S3, so as you indicated, you need to copy it to a new name and then deleted the old one:

client.copy_object(Bucket="BucketName", CopySource="BucketName/OriginalName", Key="NewName")client.delete_object(Bucket="BucketName", Key="OriginalName")


Following examples from updated Boto3 documentation for the copy() method, which also works with copy_object() and appears to be the required syntax now:

copy_source = {'Bucket': 'source__bucket', 'Key': 'my_folder/my_file'}s3.copy_object(CopySource = copy_source, Bucket = 'dest_bucket', Key = 'new_folder/my_file')s3.delete_object(Bucket = 'source_bucket', Key = 'my_folder/my_file')

Note from documentation linked above:

CopySource (dict) -- The name of the source bucket, key name of the source object, and optional version ID of the source object. The dictionary format is: {'Bucket': 'bucket', 'Key': 'key', 'VersionId': 'id'}. Note that the VersionId key is optional and may be omitted.
