Kubernetes Networking

In this Kubernetes Networking workshop, you will deploy a helloworld application from https://github.com/remkohdev/helloworld and apply different service types and networking policies to controll access to the cluster and application.

Labs

1. Lab00 - Setup
2. Lab01 - Services and ClusterIP, see Lab01
3. Lab02 - NodePort, see Lab02
4. Lab03 - Loadbalancer and Network Load Balancer (NLB) 1.0, see Lab03,
5. Lab04 - Ingress and Application Load Balancer (ALB), see Lab04
6. Lab05 - Kubernetes Network Policy and Calico, see Lab05

Prerequisites

1. Kubernetes Cluster
   • For Lab01 and Lab02 about Service types ClusterIP and NodePort you can use a single worker node Kubernetes cluster.
   • For Lab02 and Lab04 about Service type LoadBalancer and Ingress you need to have a Kubernetes cluster with a minimum of two worker nodes.
   • For Lab05 about Kubernetes Network Policy and Calico, you need.
2. Client, recommended to use IBM Cloud shell at https://shell.cloud.ibm.com.
