Configuring an IAM role for S3 Batch Replication - Amazon Simple Storage Service

Configuring an IAM role for S3 Batch Replication

Because Amazon S3 Batch Replication is a type of Batch Operations job, you must create an AWS Identity and Access Management (IAM) role to grant Batch Operations permissions to perform actions on your behalf. You also must attach a Batch Replication IAM policy to the Batch Operations IAM role.

Use the following procedures to create a policy and an IAM role that give Batch Operations permission to initiate a Batch Replication job.

To create a policy for Batch Replication

  1. Sign in to the AWS Management Console and open the IAM console at https://console.aws.amazon.com/iam/.

  2. Under Access management, choose Policies.

  3. Choose Create policy.

  4. On the Specify permissions page, choose JSON.

  5. Insert one of the following policies, depending on whether your manifest is generated by Amazon S3 or whether you are supplying your own manifest. For more information about manifests, see Specifying a manifest for a Batch Replication job.

    Before using these policies, replace the user input placeholders in the following policies with the names of your replication source bucket, manifest bucket, and completion report bucket.

    Note

    Your IAM role for Batch Replication needs different permissions, depending on whether you are generating a manifest or supplying one, so make sure that you choose the appropriate policy from the following examples.

    Policy if using and storing an Amazon S3 generated manifest

    {
   "Version":"2012-10-17",
   "Statement":[
      {
         "Action":[
            "s3:InitiateReplication"
         ],
         "Effect":"Allow",
         "Resource":[
            "arn:aws:s3:::amzn-s3-demo-source-bucket/*"
         ]
      },
      {
         "Action":[
            "s3:GetReplicationConfiguration",
            "s3:PutInventoryConfiguration"
         ],
         "Effect":"Allow",
         "Resource":[
            "arn:aws:s3:::amzn-s3-demo-source-bucket"
         ]
      },
      {
         "Action":[
            "s3:GetObject",
            "s3:GetObjectVersion"
         ],
         "Effect":"Allow",
         "Resource":[
            "arn:aws:s3:::amzn-s3-demo-manifest-bucket/*"
         ]
      },
      {
         "Effect":"Allow",

         ],
         "Resource":[
            "arn:aws:s3:::amzn-s3-demo-completion-report-bucket/*",
            "arn:aws:s3:::amzn-s3-demo-manifest-bucket/*"    
         ]
      }
   ]
}

    Policy if using a user-supplied manifest

    {
   "Version":"2012-10-17",

         "Action":[
            "s3:InitiateReplication"
         ],

            "arn:aws:s3:::amzn-s3-demo-source-bucket/*"
         ]
      },
            {

         ],
         "Effect":"Allow",

            "arn:aws:s3:::amzn-s3-demo-manifest-bucket/*"
         ]
      },
      {
         "Effect":"Allow",
         "Action":[
            "s3:PutObject"
         ],
         "Resource":[
            "arn:aws:s3:::amzn-s3-demo-completion-report-bucket/*"    
         ]
      }
   ]
}
