Managed nodegroup degradation after AdditionalEKSAdminRoleArn AdditionalEKSAdminUserArn modification

[tomiszili]

Hi!

I had a properly working EKS cluster without AdditionalEKSAdminRoleArn and AdditionalEKSAdminUserArn specified. I added managed node groups to the cluster and everything was fine. But when i updated the stack with the AdditionalEKSAdminRoleArn and AdditionalEKSAdminUserArn later i got the following error in the EKS console compute section:

I have to manually fix the configmap with the following code to the list of the mapRoles section: {"rolearn":"arn:aws:iam::<account_id>:role/eks-quickstart-test-ManagedNodeInstance","username":"system:node:{{EC2PrivateDNSName}}","groups":["system:bootstrappers","system:nodes"]}

The quickstart template should be fixed to work properly.
