Amazon EKS clusters can utilize IAM roles and policies for Pods to establish precise access control to AWS services by integrating AWS IAM entities with Kubernetes RBAC, thus facilitating least-privileged access for applications. This is achieved through the use of an OpenID Connect (OIDC) provider that verifies Pod identity and collaborates with AWS Secure Token Service (STS) to grant temporary credentials for IAM roles. The process involves creating an OIDC provider within the EKS cluster, configuring IAM roles and policies for specific applications like an S3 app, and deploying the app with IAM-backed Service Accounts. The integration automates Pod identity management and credential injection, enabling secure and effective access to AWS resources. This method can be extended with Kubernetes RBAC for more granular control over API resources, offering a native and secure experience for users. Additional resources and examples are provided for further exploration and implementation of EKS and OIDC provider for Pod IAM.
