Is there an S3 policy for limiting access to only see/access one bucket?

Question

I have a simple bucket that looks like images.mysite.com on my S3 and other buckets containing backups, etc.

I want to allow a specific user to be able

Answer 1

Try this policy. User cannot list any bucket, they have to use direct link to allowed bucket.

For example: s3.console.aws.amazon.com/s3/buckets/bucketname/?region=us-east-1&tab=overview

{
  "Statement": [
    {
      "Action": [
        "s3:ListBucket"
      ],
      "Effect": "Allow",
      "Resource": [
        "arn:aws:s3:::bucketname"
      ]
    },
    {
      "Action": [
        "s3:PutObject",
        "s3:GetObject"
      ],
      "Effect": "Allow",
      "Resource": [
        "arn:aws:s3:::bucketname*"
      ]
    },

  ],
