Set up credentials for Amazon S3

Step 1: Create an IAM policy

1. Open AWS Management Console.

2. Choose IAM > Policy, and choose Create Policy.

3. Create a policy. You can follow the example below to use IAM policy statement with minimum permissions, and change the <your-bucket-name> in the policy statement accordingly.

Note

For S3 buckets in AWS China Regions, make sure you also change to use arn:aws-cn:s3::: instead of arn:aws:s3:::.

Policy for source bucket

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Sid": "dth",
            "Effect": "Allow",
            "Action": [
                "s3:GetObject",
                "s3:ListBucket"
            ],
            "Resource":[
                "arn:aws:s3:::<your-bucket-name>/*",
                "arn:aws:s3:::<your-bucket-name>"
            ]
        }
    ]
}

Policy for destination bucket

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Sid": "dth",
            "Effect": "Allow",
            "Action": [
                "s3:PutObject",
                "s3:ListBucket",
                "s3:PutObjectAcl",
                "s3:AbortMultipartUpload",
                "s3:ListBucketMultipartUploads",
                "s3:ListMultipartUploadParts"
            ],
            "Resource": [
                "arn:aws:s3:::<your-bucket-name>/*",
                "arn:aws:s3:::<your-bucket-name>"
            ]
        }
    ]
}

To enable S3 Delete Event, you need to add "s3:DeleteObject" permission to the policy.

Data Transfer Hub has native support for the S3 source bucket which enabled SSE-S3 and SSE-KMS. If your source bucket enabled SSE-CMK, please replace the source bucket policy with the policy for S3 SSE-KMS.

Step 2: Create a user

1. Open AWS Management Console.

2. Choose IAM > User, and choose Add User to follow the wizard to create a user with credential.

3. Specify a user name, for example, dth-user.

4. For Access Type, select Programmatic access only and choose Next: Permissions.

5. Select Attach existing policies directly, search and use the policy created in Step 1, and choose Next: Tags.

6. Add tags if needed, and choose Next: Review.

7. Review the user details, and choose Create User.

8. Make sure you copied/saved the credential, and then choose Close.
