Hello,

You can check eks authentication mode from this link: https://docs.aws.amazon.com/eks/latest/userguide/setting-up-access-entries.html, for examples: 'API_AND_CONFIG_MAP','CONFIG_MAP','API'.

If 'API_AND_CONFIG_MAP' or 'API' , you can create new access, add iam access to the cluster: https://docs.aws.amazon.com/eks/latest/userguide/creating-access-entries.html.

if 'CONFIG_MAP', you must update auth-configmap, before that you should find out the user/role who created this eks cluster, and set aws cli credentials :https://docs.aws.amazon.com/eks/latest/userguide/auth-configmap.html
