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 as part of the cluster creation by AWS CloudFormation. 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.
Defaults
When you use the default settings for cluster creation, an IAM role for Amazon EC2 is created by the cluster. The user that is creating the cluster must have the right level of permissions to create all of the resources required to launch the cluster, including an IAM role for Amazon EC2. Typically, the IAM user must have the permissions of an AdministratorAccess managed policy. For details 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
as individual policies in IAM and then
attach
to the appropriate resources. In both policies, replace <REGION>, <AWS
ACCOUNT ID>, and similar strings with the appropriate values.
ParallelClusterInstancePolicy
The following example sets the ParallelClusterInstancePolicy, using SGE, Slurm, or Torque as the
scheduler:
{ "Version": "2012-10-17", "Statement": [ { "Action": [ "ec2:DescribeVolumes", "ec2:AttachVolume", "ec2:DescribeInstanceAttribute", "ec2:DescribeInstanceStatus", "ec2:DescribeInstances", "ec2:DescribeRegions" ], "Resource": [ "*" ], "Effect": "Allow", "Sid": "EC2" }, { "Action": [ "dynamodb:ListTables" ], "Resource": [ "*" ], "Effect": "Allow", "Sid": "DynamoDBList" }, { "Action": [ "sqs:SendMessage", "sqs:ReceiveMessage", "sqs:ChangeMessageVisibility", "sqs:DeleteMessage", "sqs:GetQueueUrl" ], "Resource": [ "arn:aws:sqs:<REGION>:<AWS ACCOUNT ID>:parallelcluster-*" ], "Effect": "Allow", "Sid": "SQSQueue" }, { "Action": [ "autoscaling:DescribeAutoScalingGroups", "autoscaling:TerminateInstanceInAutoScalingGroup", "autoscaling:SetDesiredCapacity", "autoScaling:UpdateAutoScalingGroup", "autoscaling:DescribeTags", "autoScaling:SetInstanceHealth" ], "Resource": [ "*" ], "Effect": "Allow", "Sid": "Autoscaling" }, { "Action": [ "cloudformation:DescribeStacks", "cloudformation:DescribeStackResource" ], "Resource": [ "arn:aws:cloudformation:<REGION>:<AWS ACCOUNT ID>:stack/parallelcluster-*/*" ], "Effect": "Allow", "Sid": "CloudFormation" }, { "Action": [ "dynamodb:PutItem", "dynamodb:Query", "dynamodb:GetItem", "dynamodb:DeleteItem", "dynamodb:DescribeTable" ], "Resource": [ "arn:aws:dynamodb:<REGION>:<AWS ACCOUNT ID>:table/parallelcluster-*" ], "Effect": "Allow", "Sid": "DynamoDBTable" }, { "Action": [ "s3:GetObject" ], "Resource": [ "arn:aws:s3:::<REGION>-aws-parallelcluster/*" ], "Effect": "Allow", "Sid": "S3GetObj" }, { "Action": [ "s3:PutObject" ], "Resource": [ "arn:aws:s3:::NONE/batch/*" ], "Effect": "Allow", "Sid": "S3PutObj" }, { "Resource": [ "*" ], "Action": [ "sqs:ListQueues" ], "Effect": "Allow", "Sid": "SQSList" }, { "Action": [ "iam:PassRole" ], "Resource": [ "arn:aws:iam::<AWS ACCOUNT ID>:role/parallelcluster-*" ], "Effect": "Allow", "Sid": "BatchJobPassRole" } ] }
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. Here is an overview
of the required permissions:
{ "Version": "2012-10-17", "Statement": [ { "Action": [ "batch:SubmitJob", "batch:RegisterJobDefinition", "cloudformation:DescribeStacks", "ecs:ListContainerInstances", "ecs:DescribeContainerInstances", "logs:GetLogEvents", "logs:FilterLogEvents", "s3:PutObject", "s3:Get*", "s3:DeleteObject", "iam:PassRole" ], "Resource": [ "arn:aws:batch:<REGION>:<AWS ACCOUNT ID>:job-definition/<AWS_BATCH_STACK - JOB_DEFINITION_SERIAL_NAME>:1", "arn:aws:batch:<REGION>:<AWS ACCOUNT ID>:job-definition/<AWS_BATCH_STACK - JOB_DEFINITION_MNP_NAME>*", "arn:aws:batch:<REGION>:<AWS ACCOUNT ID>:job-queue/<AWS_BATCH_STACK - JOB_QUEUE_NAME>", "arn:aws:cloudformation:<REGION>:<AWS ACCOUNT ID>:stack/<STACK NAME>/*", "arn:aws:s3:::<RESOURCES S3 BUCKET>/batch/*", "arn:aws:iam::<AWS ACCOUNT ID>:role/<AWS_BATCH_STACK - JOB_ROLE>", "arn:aws:ecs:<REGION>:<AWS ACCOUNT ID>:cluster/<ECS COMPUTE ENVIRONMENT>", "arn:aws:ecs:<REGION>:<AWS ACCOUNT ID>:container-instance/*", "arn:aws:logs:<REGION>:<AWS ACCOUNT ID>:log-group:/aws/batch/job:log-stream:*" ], "Effect": "Allow" }, { "Action": [ "s3:List*" ], "Resource": [ "arn:aws:s3:::<RESOURCES S3 BUCKET>" ], "Effect": "Allow" }, { "Action": [ "batch:DescribeJobQueues", "batch:TerminateJob", "batch:DescribeJobs", "batch:CancelJob", "batch:DescribeJobDefinitions", "batch:ListJobs", "batch:DescribeComputeEnvironments", "ec2:DescribeInstances" ], "Resource": "*", "Effect": "Allow" } ] }
ParallelClusterUserPolicy
The following example sets the ParallelClusterUserPolicy, using SGE, Slurm, or Torque as the
scheduler:
{ "Version": "2012-10-17", "Statement": [ { "Sid": "EC2Describe", "Action": [ "ec2:DescribeKeyPairs", "ec2:DescribeRegions", "ec2:DescribeVpcs", "ec2:DescribeSubnets", "ec2:DescribeSecurityGroups", "ec2:DescribePlacementGroups", "ec2:DescribeImages", "ec2:DescribeInstances", "ec2:DescribeInstanceStatus", "ec2:DescribeSnapshots", "ec2:DescribeVolumes", "ec2:DescribeVpcAttribute", "ec2:DescribeAddresses", "ec2:CreateTags", "ec2:DescribeNetworkInterfaces", "ec2:DescribeAvailabilityZones" ], "Effect": "Allow", "Resource": "*" }, { "Sid": "EC2Modify", "Action": [ "ec2:CreateVolume", "ec2:RunInstances", "ec2:AllocateAddress", "ec2:AssociateAddress", "ec2:AttachNetworkInterface", "ec2:AuthorizeSecurityGroupEgress", "ec2:AuthorizeSecurityGroupIngress", "ec2:CreateNetworkInterface", "ec2:CreateSecurityGroup", "ec2:ModifyVolumeAttribute", "ec2:ModifyNetworkInterfaceAttribute", "ec2:DeleteNetworkInterface", "ec2:DeleteVolume", "ec2:TerminateInstances", "ec2:DeleteSecurityGroup", "ec2:DisassociateAddress", "ec2:RevokeSecurityGroupIngress", "ec2:RevokeSecurityGroupEgress", "ec2:ReleaseAddress", "ec2:CreatePlacementGroup", "ec2:DeletePlacementGroup" ], "Effect": "Allow", "Resource": "*" }, { "Sid": "AutoScalingDescribe", "Action": [ "autoscaling:DescribeAutoScalingGroups", "autoscaling:DescribeAutoScalingInstances" ], "Effect": "Allow", "Resource": "*" }, { "Sid": "AutoScalingModify", "Action": [ "autoscaling:CreateAutoScalingGroup", "ec2:CreateLaunchTemplate", "ec2:ModifyLaunchTemplate", "ec2:DeleteLaunchTemplate", "ec2:DescribeLaunchTemplates", "ec2:DescribeLaunchTemplateVersions", "autoscaling:PutNotificationConfiguration", "autoscaling:UpdateAutoScalingGroup", "autoscaling:PutScalingPolicy", "autoscaling:DescribeScalingActivities", "autoscaling:DeleteAutoScalingGroup", "autoscaling:DeletePolicy", "autoscaling:DisableMetricsCollection", "autoscaling:EnableMetricsCollection" ], "Effect": "Allow", "Resource": "*" }, { "Sid": "DynamoDBDescribe", "Action": [ "dynamodb:DescribeTable" ], "Effect": "Allow", "Resource": "*" }, { "Sid": "DynamoDBModify", "Action": [ "dynamodb:CreateTable", "dynamodb:DeleteTable", "dynamodb:TagResource" ], "Effect": "Allow", "Resource": "*" }, { "Sid": "SQSDescribe", "Action": [ "sqs:GetQueueAttributes" ], "Effect": "Allow", "Resource": "*" }, { "Sid": "SQSModify", "Action": [ "sqs:CreateQueue", "sqs:SetQueueAttributes", "sqs:DeleteQueue", "sqs:TagQueue" ], "Effect": "Allow", "Resource": "*" }, { "Sid": "SNSDescribe", "Action": [ "sns:ListTopics", "sns:GetTopicAttributes" ], "Effect": "Allow", "Resource": "*" }, { "Sid": "SNSModify", "Action": [ "sns:CreateTopic", "sns:Subscribe", "sns:DeleteTopic" ], "Effect": "Allow", "Resource": "*" }, { "Sid": "CloudFormationDescribe", "Action": [ "cloudformation:DescribeStackEvents", "cloudformation:DescribeStackResource", "cloudformation:DescribeStackResources", "cloudformation:DescribeStacks", "cloudformation:ListStacks", "cloudformation:GetTemplate" ], "Effect": "Allow", "Resource": "*" }, { "Sid": "CloudFormationModify", "Action": [ "cloudformation:CreateStack", "cloudformation:DeleteStack", "cloudformation:UpdateStack" ], "Effect": "Allow", "Resource": "*" }, { "Sid": "S3ParallelClusterReadOnly", "Action": [ "s3:Get*", "s3:List*" ], "Effect": "Allow", "Resource": [ "arn:aws:s3:::<REGION>-aws-parallelcluster*" ] }, { "Sid": "IAMModify", "Action": [ "iam:PassRole", "iam:CreateRole", "iam:CreateServiceLinkedRole", "iam:DeleteRole", "iam:GetRole", "iam:TagRole", "iam:SimulatePrincipalPolicy" ], "Effect": "Allow", "Resource": "arn:aws:iam::<AWS ACCOUNT ID>:role/<PARALLELCLUSTER EC2 ROLE NAME>" }, { "Sid": "IAMCreateInstanceProfile", "Action": [ "iam:CreateInstanceProfile", "iam:DeleteInstanceProfile" ], "Effect": "Allow", "Resource": "arn:aws:iam::<AWS ACCOUNT ID>:instance-profile/*" }, { "Sid": "IAMInstanceProfile", "Action": [ "iam:AddRoleToInstanceProfile", "iam:RemoveRoleFromInstanceProfile", "iam:GetRolePolicy", "iam:GetPolicy", "iam:AttachRolePolicy", "iam:DetachRolePolicy", "iam:PutRolePolicy", "iam:DeleteRolePolicy" ], "Effect": "Allow", "Resource": "*" }, { "Sid": "EFSDescribe", "Action": [ "elasticfilesystem:DescribeMountTargets", "elasticfilesystem:DescribeMountTargetSecurityGroups", "ec2:DescribeNetworkInterfaceAttribute" ], "Effect": "Allow", "Resource": "*" }, { "Sid": "SSMDescribe", "Action": [ "ssm:GetParametersByPath" ], "Effect": "Allow", "Resource": "*" }, { "Sid": "FSx", "Effect": "Allow", "Action": [ "fsx:*" ], "Resource": "*" } ] }
