// Creates an EKS Pod Identity association between a service account in an Amazon
// EKS cluster and an IAM role with EKS Pod Identity. Use EKS Pod Identity to give
// temporary IAM credentials to pods and the credentials are rotated automatically.
// Amazon EKS Pod Identity associations provide the ability to manage credentials
// for your applications, similar to the way that Amazon EC2 instance profiles
// provide credentials to Amazon EC2 instances. If a pod uses a service account
// that has an association, Amazon EKS sets environment variables in the containers
// of the pod. The environment variables configure the Amazon Web Services SDKs,
// including the Command Line Interface, to use the EKS Pod Identity credentials.
// Pod Identity is a simpler method than IAM roles for service accounts, as this
// method doesn't use OIDC identity providers. Additionally, you can configure a
// role for Pod Identity once, and reuse it across clusters.
