AWS recently introduced AWS Elastic Container Service for Kubernetes (EKS), it also open-sourced a new CNI plug-in that enables pods within EKS to use VPC networking fabric. This greatly simplifies the network connectivity within a Kubernetes cluster. The CNI is the primary plugin that is used to power Amazon EKS, and is being developed in collaboration with the community. This talk will share the implementation details of the CNI plug-in, and will discuss how the plug-in has been integrated with Calico to achieve micro-segmentation between pods running inside a cluster using Kubernetes network policy.
