How to generate a kubeconfig file for Amazon EKS cluster

Many of our customers have been facing an AccessDeniedException error when they attempt to generate a kubeconfig file for an Amazon Elastic Kubernetes Service cluster. Fortunately, our Support Engineers have an easy solution for this issue.

It involves getting permission to use the eks:DescribeCluster API action. In other words, we have to attach an IAM policy to an IAM user.

How to attach an IAM policy to an IAM user

1. First, open the IAM console.
2. Then, choose Users or Roles in the navigation pane.
3. Next, we have to choose the name of the user or role we plan to embed the policy in.
4. After that, select the Add inline policy on the Permissions tab.
5. Then, we will select the JSON tab.
6. Next, we will replace the code with the IAM policy below with a text editor:

   {
      "Version": "2012-10-17",
      "Statement": [
          {
               "Effect": "Allow",
               "Action": [
                   "eks:DescribeCluster"
               ],
               "Resource": "*"
          }
       ]
   }

7. After that, we select Review policy and enter a name for the policy in the Name field.
8. Then, we will select Create policy. Our Support Team would like to point out that an explicit deny message indicates that if the MFA is false, it is likely there is an IAM policy that is denying the actions.
   

   {
     "Version": "2012-10-17",
     "Statement": [
       {
         "Sid": "BlockMostAccessUnlessSignedInWithMFA",
         "Effect": "Deny",
         "NotAction": [
           "iam:CreateVirtualMFADevice",
           "iam:EnableMFADevice",
           "iam:ListMFADevices",
           "iam:ListUsers",
           "iam:ListVirtualMFADevices",
           "iam:ResyncMFADevice",
           "sts:GetSessionToken"
         ],
         "Resource": "*",
         "Condition": {
           "BoolIfExists": {
             "aws:MultiFactorAuthPresent": "false"
           }
         }
       }
     ]
   }
