Overview

Worker nodes in an Amazon EKS Cluster will operate either in a public or a private subnet. If the subnet’s traffic does not have a default route through an Internet Gateway, this subnet is considered to be private. There are three ways to configure the VPC for your Amazon EKS cluster:

Only Public Subnets Worker Nodes and Ingress resources (like load balancers) all are instantiated in the same public subnets.

Only Public and Private Subnets Worker Nodes are instantiated in private subnets and ingress resources (like load balancers) are instantiated in the public subnets.

Only Private Subnets There are no public ingress resources as this configuration is only used for workloads that do not need to receive any communications from the public internet.

Defaults
