How to upload a file to S3 and make it public using boto3?

Question

I am able to upload an image file using:

s3 = session.resource('s3') bucket = s3.Bucket(S3_BUCKET) bucket.upload_file(file, key) 

However, I want to make the file public too. I tried looking up for some functions to set ACL for the file but seems like boto3 have changes their API and removed some functions. Is there a way to do it in the latest release of boto3?

Answer 1

To upload and set permission to publicly-readable in one step, you can use:

bucket.upload_file(file, key, ExtraArgs={'ACL':'public-read'})

See https://boto3.amazonaws.com/v1/documentation/api/latest/guide/s3-uploading-files.html#the-extraargs-parameter

Answer 2

I was able to do it using objectAcl API:

s3 = boto3.resource('s3') object_acl = s3.ObjectAcl('bucket_name','object_key') response = object_acl.put(ACL='public-read')
