Configure Kubernetes Networking, Services, and Ingress
In this lab, you’ll practice using the Container Network Interface (CNI) plugin to configure your cluster networking. You will also deploy Service and Ingress Kubernetes resources. When you’re finished, you’ll have hands-on knowledge of Kubernetes networking, and will know how to expose your applications within and outside of your cluster.

Get Started in the Lab Environment
Here are the initial instructions and explanation of the lab environment. Read this while your environment is busy creating itself from nothing. Yes, this violates physics; we know. How fun!

Challenge
Inspect the CNI Plugin
The Container Network Interface (CNI) plugin is a critical component of the Kubernetes cluster–it ensures that different applications can communicate within and outside of the cluster. To start this lab, you will check the CNI plugin configured in your Kubernetes environment and review its configuration.

Challenge
Manage DNS
Kubernetes creates DNS records for services and pods so you can contact services using consistent DNS names instead of IP addresses. In this challenge, you will learn more about the DNS resolution, and how Kubernetes dynamically creates and removes DNS records as resources are updated.
-
Challenge
Deploy Kubernetes Services
A Service is a method for exposing a network application that is running as one or more Pods in your cluster. You will learn about the different types of Service resources that are available, and you will configure the most important ones like ClusterIP and NodePort.

Challenge
Expose Applications with Ingress Resources
Services are usually used to expose an app within the cluster. The Ingress resource allows you to expose the http applications easily within your cluster. In this challenge, you will learn more about the Ingress resource, and create a sample application that exposes an http endpoint using Ingress.

Challenge
Work with Gateway API
Gateway API is a Kubernetes add-on which provides dynamic infrastructure provisioning and advanced traffic routing. You will configure, deploy, and test a Gateway API resource.
