Technical requirements

Before starting, you need the following to run the examples in this chapter:

• A Raspberry Pi cluster with K3s installed
• kubectl configured to access your cluster
• Helm installed and configured

Note

If you don’t want to use Traefik and you want to omit the default installation of this ingress controller in your cluster, add the --no-deploy traefik --disable traefik flags when you are installing your master node. For other details of installing your K3s cluster, refer to Chapter 3, K3S Advanced Configurations and Management, or visit https://rancher.com/docs/k3s/latest/en/installation/install-options/server-config/. Remember to install a bare metal load balancer such as MetalLB, which is necessary to generate a load balancer service, which is needed to install ingress controllers.

With these requirements, you are going to experiment with exposing your applications in different ways.
