Amazon Elastic Kubernetes Service (EKS) released customer-routed control plane egress, enabling outbound control plane traffic such as admission webhooks and OIDC lookups to traverse customers' own VPCs. This shift permits full routing and security control over Kubernetes API server egress paths.
This capability is especially useful for organizations with strict data perimeter or compliance needs, allowing access to private OIDC providers or webhook servers reachable only within private networks. Customers can enable this setting when creating or updating clusters, with policy enforcement via IAM condition keys. This feature is free and available in all AWS regions supporting EKS.
