uploading file to specific folder in S3 using boto3

Question

Everything with my code works. The only pitfall I am currently facing is that I cannot specify the folder within the S3 bucket that I would like to place my file in. Here is what I have:

s3.meta.client.upload_file('/tmp/'+filename, '<bucket-name>', filename)

I have tried both:

s3.meta.client.upload_file('/tmp/'+filename, '<bucket-name>/folder/', filename)

and:

s3.meta.client.upload_file('/tmp/'+filename, '<bucket-name>', '/folder/'+filename)

if anyone has any tips on how to direct this to a specific folder (if this is possible) please let me know!

Answer 1

You do not need to pass the Key value as an absolute path. The following should work:

upload_file('/tmp/' + filename, '<bucket-name>', 'folder/{}'.format(filename))

Answer 2

I figured out my problem. I had the right idea with the /folder/ option in the key parameter area, however, I did not need the first / Thank you all! This is essentially the same idea as hjpotter92's suggestion above.

Answer 3

Use this for python 3.x

s3.upload_file(file_path,bucket_name, '%s/%s' % (bucket_folder,dest_file_name))

Answer 4

You can use put_object in the place of upload_file:

file = open(r"/tmp/" + filename)
response = s3.meta.client.Bucket('<bucket-name>').put_object(Key='folder/{}'.format(filename), Body=file)
