Amazon EKS - Deploy Cilium CNI and Secure Pod Communications using Network Policies

Cilium is an open source software for providing, securing and observing network connectivity between container workloads - cloud native, and fueled by the revolutionary Kernel technology eBPF.

In this Lab scenario, you'll learn how to reconfigure an EKS cluster to utilize Cilium as it's CNI provider. 

You'll also learn how to deploy a sample Star Wars themed application into the cluster, and then secure it using Cilium based Network Policies.

May the force be with you!
