Is not authorized to perform: eks:listclusters on resource
In the rapidly evolving world of cloud computing, Amazon Elastic Kubernetes Service (EKS) has emerged as a preferred choice for organizations seeking to leverage the power of Kubernetes without the complexity of managing the underlying infrastructure. However, one common challenge faced by users is encountering the error message “is not authorized to perform: eks:listclusters on resource.” This article aims to shed light on the nature of this error, its implications, and potential solutions to resolve it effectively.
The error message “is not authorized to perform: eks:listclusters on resource” indicates that the user attempting to list the clusters within Amazon EKS does not possess the necessary permissions to perform this action. This error can occur due to various reasons, such as incorrect IAM roles, insufficient permissions, or misconfigured policies.
Understanding IAM Roles and Policies
To understand the root cause of this error, it is essential to have a basic understanding of IAM (Identity and Access Management) roles and policies in AWS. IAM roles and policies are used to define and control the permissions for AWS resources, including EKS clusters.
IAM roles are essentially trust relationships between an AWS account and an AWS service, allowing the service to assume the role on behalf of the user. Policies, on the other hand, are JSON documents that define the permissions for a particular IAM entity, such as a user or role.
Resolving the “is not authorized to perform: eks:listclusters on resource” Error
To resolve the “is not authorized to perform: eks:listclusters on resource” error, follow these steps:
1. Verify IAM Roles: Ensure that the IAM role assigned to the user or service account has the necessary permissions to list EKS clusters. The required permissions include the following policies:
– AmazonEKSFullAccess
– AmazonEKSClusterAccess
– AmazonEKSServiceRoleForCluster
2. Check Policy Attachments: Review the policies attached to the IAM role or user to ensure they grant the required permissions. If the necessary permissions are missing, you can create a custom policy or modify an existing one to grant the required access.
3. Correct Resource Permissions: If the error persists, verify that the resource (EKS cluster) itself has the correct permissions set. Ensure that the IAM role or user has the necessary permissions to access the EKS cluster resource.
4. Review CloudFormation Templates: If you are using CloudFormation templates to create EKS clusters, review the template to ensure that the IAM role assigned to the cluster has the required permissions.
5. Enable Debugging: To gain more insight into the issue, enable AWS CloudTrail logging for your account. This will provide you with detailed logs of all API calls and help identify the specific permissions issue.
By following these steps, you should be able to resolve the “is not authorized to perform: eks:listclusters on resource” error and regain access to your EKS clusters. It is crucial to have a well-defined IAM role and policy structure to ensure that users and services have the necessary permissions without compromising security.
