use python to set up the permissions recursively

#!/usr/bin/env python
import boto3
import sys

client = boto3.client('s3')
BUCKET='enter-bucket-name'

def process_s3_objects(prefix):
    """Get a list of all keys in an S3 bucket."""
    kwargs = {'Bucket': BUCKET, 'Prefix': prefix}
    failures = []
    while_true = True
    while while_true:
      resp = client.list_objects_v2(**kwargs)
      for obj in resp['Contents']:
        try:
            print(obj['Key'])
            set_acl(obj['Key'])
            kwargs['ContinuationToken'] = resp['NextContinuationToken']
        except KeyError:
            while_true = False
        except Exception:
            failures.append(obj["Key"])
            continue

    print "failures :", failures

def set_acl(key):
  client.put_object_acl(     
    GrantFullControl="id=%s" % get_account_canonical_id,
    Bucket=BUCKET,
    Key=key
)

def get_account_canonical_id():
  return client.list_buckets()["Owner"]["ID"]
