AWS Identity and Access Management roles in AWS ParallelCluster

AWS ParallelCluster uses AWS Identity and Access Management (IAM) roles for Amazon EC2 to enable instances to access AWS services for the deployment and operation of a cluster. By default, the IAM role for Amazon EC2 is created when the cluster is created. This means that the user that creates the cluster must have the appropriate level of permissions, as described in the following sections.

AWS ParallelCluster uses multiple AWS services to deploy and operate a cluster. See the complete list in the AWS Services used in AWS ParallelCluster section.

Default settings for cluster creation

When you use the default settings for cluster creation, an IAM role for Amazon EC2 is created by the cluster. The user that creates the cluster must have the right level of permissions to create all of the resources required to launch the cluster. This includes an IAM role for Amazon EC2. Typically, the IAM user must have the permissions of an AdministratorAccess managed policy. For information about managed policies, see AWS managed policies in the IAM User Guide.

Using an existing IAM role for Amazon EC2

You can use an existing IAM role for Amazon EC2 when creating a cluster, but you must first define the IAM policy and role before attempting to launch the cluster. Typically, you choose an existing IAM role for Amazon EC2 to reduce the permissions that are granted to users as they launch clusters. The following example shows an IAM policy and role for both Amazon EC2 and the AWS ParallelCluster. You must create both policies and roles as individual policies in IAM and then attach the roles and policies to the appropriate resources. In the policies, replace <REGION>, <AWS ACCOUNT ID>, and similar strings with the appropriate values.

AWS ParallelCluster example instance and user policies

The following example policies include Amazon Resource Names (ARNs) for the resources. If you're working in the AWS GovCloud (US) or AWS China partitions, the ARNs must be changed. Specifically, they must be changed from "arn:aws" to "arn:aws-us-gov" for the AWS GovCloud (US) partition or "arn:aws-cn" for the AWS China partition. For more information, see Amazon Resource Names (ARNs) in AWS GovCloud (US) Regions in the AWS GovCloud (US) User Guide and ARNs for AWS services in China in Getting Started with AWS services in China.

ParallelClusterInstancePolicy using SGE, Slurm, or Torque

The following example sets the ParallelClusterInstancePolicy using SGE, Slurm, or Torque as the scheduler.

ParallelClusterInstancePolicy using awsbatch

The following example sets the ParallelClusterInstancePolicy using awsbatch as the scheduler. You must include the same policies that are assigned to the BatchUserRole that is defined in the AWS Batch AWS CloudFormation nested stack. The BatchUserRole ARN is provided as a stack output. In this example, “<RESOURCES S3 BUCKET>” is the value of the cluster_resource_bucket setting; if cluster_resource_bucket is not specified then “<RESOURCES S3 BUCKET>” is “parallelcluster-*”. The following example is an overview of the required permissions:

ParallelClusterUserPolicy using Slurm

The following example sets the ParallelClusterUserPolicy, using Slurm as the scheduler. In this example, “<RESOURCES S3 BUCKET>” is the value of the cluster_resource_bucket setting; if cluster_resource_bucket is not specified then “<RESOURCES S3 BUCKET>” is “parallelcluster-*”.

Note

If you use a custom role, ec2_iam_role = <role_name>, you must change the IAM resource to include the name of that role from:

"Resource": "arn:aws:iam::<AWS ACCOUNT ID>:role/parallelcluster-*"

To:

"Resource": "arn:aws:iam::<AWS ACCOUNT ID>:role/<role_name>"

ParallelClusterUserPolicy using SGE or Torque

The following example sets the ParallelClusterUserPolicy, using SGE or Torque as the scheduler. In this example, “<RESOURCES S3 BUCKET>” is the value of the cluster_resource_bucket setting; if cluster_resource_bucket is not specified then “<RESOURCES S3 BUCKET>” is “parallelcluster-*”.

Note

If you use a custom role, ec2_iam_role = <role_name>, you must change the IAM resource to include the name of that role from:

"Resource": "arn:aws:iam::<AWS ACCOUNT ID>:role/parallelcluster-*"

To:

"Resource": "arn:aws:iam::<AWS ACCOUNT ID>:role/<role_name>"

ParallelClusterUserPolicy using awsbatch

The following example sets the ParallelClusterUserPolicy using awsbatch as the scheduler. In this example, “<RESOURCES S3 BUCKET>” is the value of the cluster_resource_bucket setting; if cluster_resource_bucket is not specified then “<RESOURCES S3 BUCKET>” is “parallelcluster-*”.
