When only the public endpoint for the cluster is enabled, Kubernetes API requests that originate from within the Amazon VPC, such as worker node to control plane communication, leave the VPC but don't leave Amazon's network. Public endpoint onlyĮxposing the control plane via a public endpoint is the default mode for new Amazon EKS clusters. For more information, see Amazon EKS cluster endpoint access control. You can change the endpoint settings anytime through the Amazon EKS console or the API. How Amazon EKS nodes connect to the managed Kubernetes control plane is determined by which endpoint setting is configured for the cluster. When you enable the public endpoint, you can add Classless Inter-Domain Routing (CIDR) restrictions to limit the client IP addresses that can connect to the public endpoint. You can enable the default public endpoint, a private endpoint, or both endpoints simultaneously. EKS provides several ways to control access to the cluster endpoint. Amazon EKS can provision managed node groups in both public and private subnets.Įndpoint access control lets you configure whether the API Server endpoint is reachable from the public internet or through the VPC. A public subnet hosts resources that must be connected to the internet, and a private subnet hosts resources that aren't connected to the public internet. With Amazon Virtual Private Cloud (Amazon VPC), you can launch Amazon Web Services (AWS) resources into a virtual network composed of public and private subnets, or ranges of IP addresses in the VPC. This article is part of a series of articles that helps professionals who are familiar with Amazon Elastic Kubernetes Service (Amazon EKS) to understand Azure Kubernetes Service (AKS).
