How To Make S3 Bucket Public In Python

I have an already created bucket in amazon s3. I want to make its content publicly available without any authentication. I have tried from documents of boto To set a canned ACL fo

Solution 1:

You will need to create a Bucket Policy, which defines permissions on the bucket as a whole.

See 'Bucket Policy' in: Managing Access to S3 Resources (Access Policy Options)

You can do this via boto in Python with put_bucket_policy():

put_bucket_policy(**kwargs)

Replaces a policy on a bucket. If the bucket already has a policy, the one in this request completely replaces it.

Request Syntax

response = client.put_bucket_policy(Bucket='string', Policy='string')

See Bucket Policy Examples to find a suitable policy.

Here is a policy that makes the whole bucket publicly readable (just insert your own bucket name):

{
  "Version":"2012-10-17",
  "Statement":[
    {
      "Sid":"AddPerm",
      "Effect":"Allow",
      "Principal": "*",
      "Action":["s3:GetObject"],
      "Resource":["arn:aws:s3:::examplebucket/*"]
    }
  ]
}
