Look inside

As a Kubernetes administrator at Interpop, a music streaming service, you know that container applications can’t run without pod communication. Your task is to ensure connectivity between pods in the service’s cluster. You’ll connect nodes together using Weave, a container network interface (CNI). To keep communication traffic secure, you’ll implement network policies, and you’ll simplify traffic routing with the NGINX Ingress controller. You’ll learn how to troubleshoot network problems in the cluster using kubectl, and how to find solutions for pod failures. When you’re done, you’ll have experience implementing networking and troubleshooting techniques that will keep your container applications working together in harmony.

This project is designed for learning purposes and is not a complete, production-ready application or solution.
