Create a single IAM user to access only specific S3 bucket

Question

I have created an IAM user and one S3 bucket, Nad now I would like to give this user ability to access this S3 bucket using CyberDuck. 

How can I give this access to a single S3 bucket?

Answer 1

First of all, create a Policy that allows access to a single S3 bucket that you have, and will look like this:

{

  "Version": "2012-10-17",

  "Statement": [

    {

      "Sid": "Stmt1528735049406",

      "Action": [

        "s3:DeleteObject",

        "s3:GetObject",

        "s3:HeadBucket",

        "s3:ListBucket",

        "s3:ListObjects",

        "s3:PutObject"

      ],

      "Effect": "Allow",

      "Resource": "arn:aws:s3:::YOURBUCKETNAME"

    }

  ]

}

 Save the policy you created just now and then switch to "IAM user" and select the user you want. Click on "Add permission" and then select "Attach existing policies directly", look for your policy and select that.
