Amazon EKS node IAM role
The Amazon EKS node kubelet
daemon makes calls to AWS APIs on your behalf. Nodes receive
permissions for these API calls through an IAM instance profile and associated policies.
Before you can launch nodes and register them into a cluster, you must create an IAM role
for those nodes to use when they are launched. This requirement applies to nodes launched
with the Amazon EKS optimized AMI provided by Amazon, or with any other node AMIs that you intend
to use. Additionally, this requirement applies to both managed node groups and self-managed
nodes.
Note
You can't use the same role that is used to create any clusters.
Before you create nodes, you must create an IAM role with the following permissions:
-
Permissions for the
kubelet
to describe Amazon EC2 resources in the VPC, such as provided by theAmazonEKSWorkerNodePolicy
policy. This policy also provides the permissions for the Amazon EKS Pod Identity Agent. -
Permissions for the
kubelet
to use container images from Amazon Elastic Container Registry (Amazon ECR), such as provided by theAmazonEC2ContainerRegistryReadOnly
policy. The permissions to use container images from Amazon Elastic Container Registry (Amazon ECR) are required because the built-in add-ons for networking run pods that use container images from Amazon ECR. -
(Optional) Permissions for the Amazon EKS Pod Identity Agent to use the
eks-auth:AssumeRoleForPodIdentity
action to retrieve credentials for pods. If you don't use the AmazonEKSWorkerNodePolicy, then you must provide this permission in addition to the EC2 permissions to use EKS Pod Identity. -
(Optional) If you don't use IRSA or EKS Pod Identity to give permissions to the VPC CNI pods, then you must provide permissions for the VPC CNI on the instance role. You can use either the
AmazonEKS_CNI_Policy
managed policy (if you created your cluster with theIPv4
family) or an IPv6 policy that you create (if you created your cluster with theIPv6
family). Rather than attaching the policy to this role however, we recommend that you attach the policy to a separate role used specifically for the Amazon VPC CNI add-on. For more information about creating a separate role for the Amazon VPC CNI add-on, see Configuring the Amazon VPC CNI plugin for Kubernetes to use IAM roles for service accounts (IRSA).
Note
Prior to October 3, 2023, AmazonEKSWorkerNodePolicy
and AmazonEC2ContainerRegistryReadOnly
were required on the IAM
role for each managed node group.
The Amazon EC2 node groups must have a different IAM role than the Fargate profile. For more information, see Amazon EKS Pod execution IAM role.
Check for an existing node role
You can use the following procedure to check and see if your account already has the Amazon EKS node role.
To check for the
eksNodeRole
in the IAM console
Open the IAM console at https://console.aws.amazon.com/iam/
. -
In the left navigation pane, choose Roles.
-
Search the list of roles for
eksNodeRole
,AmazonEKSNodeRole
, orNodeInstanceRole
. If a role with one of those names doesn't exist, then see Creating the Amazon EKS node IAM role to create the role. If a role that containseksNodeRole
,AmazonEKSNodeRole
, orNodeInstanceRole
does exist, then select the role to view the attached policies. -
Choose Permissions.
-
Ensure that the AmazonEKSWorkerNodePolicy and AmazonEC2ContainerRegistryReadOnly managed policies are attached to the role or a custom policy is attached with the minimal permissions.
Note
If the AmazonEKS_CNI_Policy policy is attached to the role, we recommend removing it and attaching it to an IAM role that is mapped to the
aws-node
Kubernetes service account instead. For more information, see Configuring the Amazon VPC CNI plugin for Kubernetes to use IAM roles for service accounts (IRSA). -
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": "ec2.amazonaws.com" }, "Action": "sts:AssumeRole" } ] }
Creating the Amazon EKS node IAM role
You can create the node IAM role with the AWS Management Console or the AWS CLI.
