About:
A command-line tool that enables Kubernetes clusters to authenticate users and service accounts using AWS IAM credentials. It works by validating AWS IAM identities and mapping them to Kubernetes RBAC roles, eliminating the need to manage separate credentials for Kubernetes access. This provides a secure and centralized authentication mechanism for EKS and self-managed Kubernetes clusters on AWS.
Key Features:
  • Authenticates Kubernetes users via AWS IAM credentials
  • Integrates with AWS EKS and self-managed clusters
  • Provides IAM identity to Kubernetes user/group mapping
  • Supports credential verification via AWS STS
  • Enables secure, credential-less access for IAM roles
Use Cases:
  • Secure authentication for Amazon EKS clusters using IAM roles
  • Centralized access control for Kubernetes workloads running on AWS infrastructure
Alternatives:
  • kubelogin – Plugin for kubectl supporting OIDC and other providers, not AWS IAM specific
  • aws-cli – Can generate temporary tokens for EKS but lacks direct integration as an authenticator binary
