Set up IAM roles for Cloud Volumes ONTAP

02/16/2024 Contributors

IAM roles with the required permissions must be attached to each Cloud Volumes ONTAP node. The same is true for the HA mediator. It's easiest to let BlueXP create the IAM roles for you, but you can use your own roles.

This task is optional. When you create a Cloud Volumes ONTAP working environment, the default option is to let BlueXP create the IAM roles for you. If your business's security policies require you to create the IAM roles yourself, then follow the steps below.

Providing your own IAM role is required in the AWS Commercial Cloud Services Environment. Learn how to deploy Cloud Volumes ONTAP in C2S.

Steps

Go to the AWS IAM console.

Create IAM policies that include the following permissions:

Base policy for Cloud Volumes ONTAP nodes

Standard regions

{
	"Version": "2012-10-17",
	"Statement": [{
			"Action": "s3:ListAllMyBuckets",
			"Resource": "arn:aws:s3:::*",
			"Effect": "Allow"
		}, {
			"Action": [
				"s3:ListBucket",
				"s3:GetBucketLocation"
			],
			"Resource": "arn:aws:s3:::fabric-pool-*",
			"Effect": "Allow"
		}, {
			"Action": [
				"s3:GetObject",
				"s3:PutObject",
				"s3:DeleteObject"
			],
			"Resource": "arn:aws:s3:::fabric-pool-*",
			"Effect": "Allow"
		}
	]
}

}

Backup policy for Cloud Volumes ONTAP nodes

If you plan to use BlueXP backup and recovery with your Cloud Volumes ONTAP systems, the IAM role for the nodes must include the second policy shown below.

Standard regions

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Action": [

                "s3:GetBucketLocation"
            ],
            "Resource": "arn:aws:s3:::netapp-backup*",
            "Effect": "Allow"
        },
        {

Create an IAM role and attach the policies that you created to the role.

Result

You now have IAM roles that you can select when you create a new Cloud Volumes ONTAP working environment.
