Amazon Elastic Kubernetes Service (EKS) provides a managed Kubernetes service that makes it easy to run Kubernetes on AWS without needing to install and operate your own Kubernetes control plane or nodes. One of the key considerations when deploying an EKS cluster is ensuring its security and network isolation. This is where the concept of a private EKS cluster becomes crucial.
What is a Private EKS Cluster?
A private EKS cluster is one where the Kubernetes API server is accessible only within your Amazon Virtual Private Cloud (VPC). This setup restricts public internet access to the API server, enhancing security by ensuring that only resources within your VPC can communicate with the cluster.
Enabling Private Clusters in EKS
To enable a private EKS cluster, you need to set the privateCluster parameter to enabled: true in your cluster configuration. This configuration ensures that the Kubernetes API server endpoint is private, and you can access it only from within your VPC.
