How do I make all files in an S3 bucket public?

Question

My S3 Bucket was private. But now I have updated it to be public. I still can't seem to access the files without signing the URL etc. How do I make all of them public?

Answer 1

To make all objects in a bucket publicly readable, create a Bucket Policy on that specific bucket, which grants GetObject permissions for anonymous users. Replace "examplebucket" with the name of the bucket. You can add the Bucket Policy in the Amazon S3 Management Console, in the Permissions section.

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