Overview

EKS has native support for bearer tokens and bearer tokens and webhook token authentication. The bearer token is the only piece of information that carries the identity of the caller to the Kubernetes server. It consists of a pre-signed URL that includes an Amazon credential and signature.

For more details:

Generate a Token

For the current IAM User, associated with the current AWS_PROFILE:

aws eks get-token --cluster <cluster-name>

For an arbitrary IAM role:

aws eks get-token --cluster <cluster-name> --role <role-arn>
