What isAmazon Elastic Container Service for Kubernetes (Amazon EKS)

Amazon Elastic Kubernetes Service (EKS) has incorporated the Kubernetes Role-Based Access Control (RBAC) system with AWS Identity and Access Management (IAM), allowing users to securely authenticate and authorise access to Kubernetes APIs and AWS resources. This integration paves the way for corporate IT departments to set up Identity and Access Management for their Kubernetes clusters through EKS, with AWS IAM acting as the central access control hub.

FAQ: Amazon EKS and Kubernetes RBAC Integration

Amazon Elastic Kubernetes Service (EKS) is a fully managed Kubernetes service that allows you to easily run, scale, and secure your containerized applications on the AWS platform. One of the key features of EKS is its integration with Kubernetes Role-Based Access Control (RBAC) and AWS Identity and Access Management (IAM), allowing you to manage access to your cluster resources with greater precision and control.

What is Kubernetes RBAC?

Kubernetes RBAC is the built-in authentication and authorization mechanism for Kubernetes, which is a widely used open-source container orchestration platform. RBAC allows you to define granular access controls for users, groups, and service accounts that need to interact with your Kubernetes resources, such as pods, deployments, services, and namespaces.

What is AWS IAM?

AWS IAM is the identity and access management service for AWS, which enables you to manage users, groups, and roles that can access your AWS resources. IAM provides fine-grained permissions for AWS services and APIs, as well as integration with external identity providers, such as Active Directory and SAML-based federated authentication.

How does Amazon EKS integrate Kubernetes RBAC with AWS IAM?

Amazon EKS provides a seamless integration between Kubernetes RBAC and AWS IAM, allowing you to leverage the benefits of both services in a unified way. When you create an EKS cluster, AWS automatically creates an IAM role for the cluster, which grants permissions to the master nodes and worker nodes.

You can then use Kubernetes RBAC to define roles, role bindings, and service accounts that map to IAM policies, roles, and users. This allows you to manage access to your cluster resources based on the principle of least privilege, which means granting only the necessary permissions to each user or system entity.

What are the benefits of using Amazon EKS with Kubernetes RBAC and AWS IAM?

By using Amazon EKS with Kubernetes RBAC and AWS IAM, you can achieve the following benefits:

  • Enhanced security: RBAC and IAM enable you to control who can access your cluster resources and what actions they can perform. This reduces the risk of unauthorized access, privilege escalation, and data breaches.
  • Greater flexibility: RBAC and IAM allow you to assign permissions at a fine-grained level, which means you can create custom roles and policies that reflect your unique security and compliance requirements.
  • Simplified management: EKS automates many of the tasks associated with deploying and scaling Kubernetes clusters, while RBAC and IAM simplify the management of access controls and permissions.
  • Seamless integration: EKS provides a seamless integration with Kubernetes RBAC and AWS IAM, which means you can use familiar tools and workflows to manage your cluster resources.


Amazon EKS is a powerful service that integrates Kubernetes RBAC and AWS IAM, providing you with enhanced security, greater flexibility, simplified management, and seamless integration. By using these services together, you can confidently run your containerized applications on AWS, knowing that your resources are protected by industry-leading security controls.
