How to upload a file to directory in S3 bucket using boto

Question

I want to copy a file in s3 bucket using python.

Ex : I have bucket name = test. And in the bucket, I have 2 folders name "dump" & "input". Now I want to copy a file from local directory to S3 "dump" folder using python... Can anyone help me?

Answer 1

Try this...

import boto import boto.s3 import sys from boto.s3.key import Key  AWS_ACCESS_KEY_ID = '' AWS_SECRET_ACCESS_KEY = ''  bucket_name = AWS_ACCESS_KEY_ID.lower() + '-dump' conn = boto.connect_s3(AWS_ACCESS_KEY_ID,         AWS_SECRET_ACCESS_KEY)   bucket = conn.create_bucket(bucket_name,     location=boto.s3.connection.Location.DEFAULT)  testfile = "replace this with an actual filename" print 'Uploading %s to Amazon S3 bucket %s' % \    (testfile, bucket_name)  def percent_cb(complete, total):     sys.stdout.write('.')     sys.stdout.flush()   k = Key(bucket) k.key = 'my test file' k.set_contents_from_filename(testfile,     cb=percent_cb, num_cb=10) 

[UPDATE] I am not a pythonist, so thanks for the heads up about the import statements. Also, I'd not recommend placing credentials inside your own source code. If you are running this inside AWS use IAM Credentials with Instance Profiles (http://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles_use_switch-role-ec2_instance-profiles.html), and to keep the same behaviour in your Dev/Test environment, use something like Hologram from AdRoll (https://github.com/AdRoll/hologram)

import boto3  s3 = boto3.resource('s3') BUCKET = "test"  s3.Bucket(BUCKET).upload_file("your/local/file", "dump/file")
