Amazon Elastic Kubernetes Service (EKS) announces domainless Group Managed Service Account (gMSA) support for Windows containers. This helps customers to easily authenticate applications hosted on Amazon EKS with Microsoft Active Directory (AD) using a portable user identity and a plug-in mechanism to retrieve the gMSA credentials for their Windows containers. Now, customers can run containers that require AD authentication without joining the EKS nodes to the domain, even in case of autoscaling events.
