Amazon Services require valid accounts to be used. This proxy allows external users to access an AWS EKS cluster without requiring access to AWS credentials.

Disclaimer: the proxy does not implement any form of authentication. You are responsible for implementing whatever security measure you wish to enforce in front of it.

In order to give access to an AWS EKS cluster without distribution credentials, you can start the proxy with the necessary credentials as well as the cluster ID. For example, using Docker:

$ docker run --rm -p 8080:8080 \
             -e AWS_ACCESS_KEY_ID=<AWS_ACCESS_KEY_ID> \
             -e AWS_SECRET_ACCESS_KEY=<AWS_SECRET_ACCESS_KEY> \
             -e EKS_CLUSTER_ID=<EKS_CLUSTER_ID> \
    camptocamp/aws-iam-authenticator-proxy:latest

You should then be able to retrieve authentication tokens for your user at http://localhost:8080.

You can set up your ~/.kube/config to use the exec authentication mechanism using curl:

users:
- name: <cluster_name>
  user:
    exec:
      apiVersion: client.authentication.k8s.io/v1alpha1
      command: curl
      args:
        - -s
        - "http://<your_ip>:8080/"
