An Amazon EKS cluster IAM role is required for each cluster. Kubernetes clusters managed by Amazon EKS use this role to automate routine tasks for storage, networking, and compute autoscaling.
Before you can create Amazon EKS clusters, you must create an IAM role with the policies required for EKS Auto Mode. You can either attach the suggested AWS IAM managed policies, or create custom polices with equivalent permissions.
Check for an existing cluster role
You can use the following procedure to check and see if your account already has the Amazon EKS cluster role.
-
Open the IAM console at https://console.aws.amazon.com/iam/
. -
In the left navigation pane, choose Roles.
-
Search the list of roles for
AmazonEKSAutoClusterRole. If a role that includesAmazonEKSAutoClusterRoledoesn’t exist, then see the instructions in the next section to create the role. If a role that includesAmazonEKSAutoClusterRoledoes exist, then select the role to view the attached policies. -
Choose Permissions.
-
Ensure that the AmazonEKSClusterPolicy managed policy is attached to the role. If the policy is attached, your Amazon EKS cluster role is properly configured.
-
Choose Trust relationships, and then choose Edit trust policy.
-
Verify that the trust relationship contains the following policy. If the trust relationship matches the following policy, choose Cancel. If the trust relationship doesn’t match, copy the policy into the Edit trust policy window and choose Update policy.
{ "Version": "2012-10-17", "Statement": [ { "Effect": "Allow", "Principal": { "Service": "eks.amazonaws.com" }, "Action": [ "sts:AssumeRole", "sts:TagSession" ] } ] }
Note
AWS does not require the name AmazonEKSAutoClusterRole for this role.
Creating the Amazon EKS cluster role
You can use the AWS Management Console or the AWS CLI to create the cluster role.

AWS CLI
-
Copy the following contents to a file named
cluster-trust-policy.json.{ "Version": "2012-10-17", "Statement": [ { "Effect": "Allow", "Principal": { "Service": "eks.amazonaws.com" }, "Action": [ "sts:AssumeRole", "sts:TagSession" ] } ] } -
Create the role. You can replace
AmazonEKSAutoClusterRolewith any name that you choose.aws iam create-role \ --role-name AmazonEKSAutoClusterRole \ --assume-role-policy-document file://"cluster-trust-policy.json" -
Attach the required IAM policies to the role:
AmazonEKSClusterPolicy:
aws iam attach-role-policy \
--role-name AmazonEKSAutoClusterRole \
--policy-arn arn:aws:iam::aws:policy/AmazonEKSClusterPolicy
AmazonEKSComputePolicy:
aws iam attach-role-policy \
--role-name AmazonEKSAutoClusterRole \
--policy-arn arn:aws:iam::aws:policy/AmazonEKSComputePolicy
AmazonEKSBlockStoragePolicy:
aws iam attach-role-policy \
--role-name AmazonEKSAutoClusterRole \
--policy-arn arn:aws:iam::aws:policy/AmazonEKSBlockStoragePolicy
AmazonEKSLoadBalancingPolicy:
aws iam attach-role-policy \
--role-name AmazonEKSAutoClusterRole \
--policy-arn arn:aws:iam::aws:policy/AmazonEKSLoadBalancingPolicy
AmazonEKSNetworkingPolicy:
aws iam attach-role-policy \
--role-name AmazonEKSAutoClusterRole \
--policy-arn arn:aws:iam::aws:policy/AmazonEKSNetworkingPolicy
