User access policy examples for EMR Serverless

You can set up fine-grained policies for your users depending on the actions you want each user to perform when interacting with EMR Serverless applications. The following policies are examples that might help in setting up the right permissions for your users. This section focuses only on EMR Serverless policies. For samples of EMR Studio user policies, see Configure EMR Studio user permissions. For information about how to attach policies to IAM users (principals), see Managing IAM policies in the IAM User Guide.

Power user policy

To grant all the required actions for EMR Serverless, create and attach a AmazonEMRServerlessFullAccess policy to the required IAM user, role, or group.

The following is a sample policy that allows power users to create and modify EMR Serverless applications, as well as perform other actions like submitting and debugging jobs. It reveals all the actions that EMR Serverless requires for other services.

{ "Version": "2012-10-17", "Statement": [ { "Sid": "EMRServerlessActions", "Effect": "Allow", "Action": [ "emr-serverless:CreateApplication", "emr-serverless:UpdateApplication", "emr-serverless:DeleteApplication", "emr-serverless:ListApplications", "emr-serverless:GetApplication", "emr-serverless:StartApplication", "emr-serverless:StopApplication", "emr-serverless:StartJobRun", "emr-serverless:CancelJobRun", "emr-serverless:ListJobRuns", "emr-serverless:GetJobRun" ], "Resource": "*" } ] }

When you enable network connectivity to your VPC, EMR Serverless applications create Amazon EC2 elastic network interfaces (ENIs) to communicate with VPC resources. The following policy ensures that any new EC2 ENIs are only created in the context of EMR Serverless applications.

Note

We strongly recommend setting this policy to ensure that users cannot create EC2 ENIs except in the context of launching EMR Serverless applications.

{ "Version": "2012-10-17", "Statement": [ { "Sid": "AllowEC2ENICreationWithEMRTags", "Effect": "Allow", "Action": [ "ec2:CreateNetworkInterface" ], "Resource": [ "arn:aws:ec2:*:*:network-interface/*" ], "Condition": { "StringEquals": { "aws:CalledViaLast": "ops.emr-serverless.amazonaws.com" } } } }

If you want to restrict EMR Serverless access to certain subnets, you can tag each subnet with a tag condition. This IAM policy ensures that EMR Serverless applications can only create EC2 ENIs within allowed subnets.

{ "Sid": "AllowEC2ENICreationInSubnetAndSecurityGroupWithEMRTags", "Effect": "Allow", "Action": [ "ec2:CreateNetworkInterface" ], "Resource": [ "arn:aws:ec2:*:*:subnet/*", "arn:aws:ec2:*:*:security-group/*" ], "Condition": { "StringEquals": { "aws:ResourceTag/KEY": "VALUE" } } }
Important

If you’re an Administrator or power user creating your first application, you must configure your permission policies to allow you to create a EMR Serverless service-linked role. To learn more, see Using service-linked roles for EMR Serverless.

The following IAM policy permits you to create a EMR Serverless service-linked role for your account.

{ "Sid":"AllowEMRServerlessServiceLinkedRoleCreation", "Effect":"Allow", "Action":"iam:CreateServiceLinkedRole", "Resource":"arn:aws:iam::account-id:role/aws-service-role/ops.emr-serverless.amazonaws.com/AWSServiceRoleForAmazonEMRServerless" }

Data engineer policy

This following is a sample policy that allows users read-only permissions on EMR Serverless applications, as well as the the ability to submit and debug jobs. Keep in mind that because this policy does not explicitly deny actions, a different policy statement may still be used to grant access to specified actions.

{ "Version": "2012-10-17", "Statement": [ { "Sid": "EMRServerlessActions", "Effect": "Allow", "Action": [ "emr-serverless:ListApplications", "emr-serverless:GetApplication", "emr-serverless:StartApplication", "emr-serverless:StartJobRun", "emr-serverless:CancelJobRun", "emr-serverless:ListJobRuns", "emr-serverless:GetJobRun" ], "Resource": "*" } ] }

Using tags for access control

You can use tag conditions for fine-grained access control. For example, you can restrict users from one team such that they’re only able to submit jobs to EMR Serverless applications tagged with their team name.

{ "Version": "2012-10-17", "Statement": [ { "Sid": "EMRServerlessActions", "Effect": "Allow", "Action": [ "emr-serverless:ListApplications", "emr-serverless:GetApplication", "emr-serverless:StartApplication", "emr-serverless:StartJobRun", "emr-serverless:CancelJobRun", "emr-serverless:ListJobRuns", "emr-serverless:GetJobRun" ], "Resource": "*", "Condition": { "StringEquals": { "aws:ResourceTag/Team": "team-name" } } } ] }
