Hello guys I am doing the course Liveview course of the pragprog and I would like to know how to put the Amazon AWS S3 bucket to be public.

I created the bucket and put the ‘CORS’ on the ‘Permissions’.
But I can’t put this new bucket on public.
Someone could help me with this please?

My application is complaining for this:

Are you trying to make your AWS bucket public? If yes, you can simply change it here with the edit button.

I tried there before but it was unsuccessfully.
Which options you put?

After setting it to public, you can update the bucket policy to allow read and write access.

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Sid": "Allow",
            "Effect": "Allow",
            "Principal": {
                "AWS": "arn:aws:iam::<user_iam_id>:user/<bucketname>"
            },
            "Action": "s3:*",
            "Resource": [
                "arn:aws:s3:::<bucketname>/*",
                "arn:aws:s3:::<bucketname>"
            ]
        },
        {
            "Sid": "AllowAllRead",
            "Effect": "Allow",
            "Principal": "*",
            "Action": "s3:GetObject",
            "Resource": [

                "arn:aws:s3:::<bucketname>"
            ]
        }
    ]
}
