Cluster Access for Multiple AWS Users

Get the ARNs and names of users who need access to your cluster.

Set the Kubernetes context to your Amazon EKS cluster.

Edit the authorization configuration map for the cluster using the kubectl edit command:

$ kubectl edit -n kube-system configmap/aws-auth

Under the mapRoles section, insert the mapUser section. An example is shown here with the following parameters:

For each additional user, insert the - userarn: entry in the mapUsers: section:

…​ mapUsers: |
    - userarn: arn:aws:iam::012345678901:user/new.user
      username: new.user
      groups:
        - system:masters
    - userarn: arn:aws:iam::901234567890:user/second.user
      username: second.user
      groups:
        - system:masters
…​

Save the configuration map.
