Summary

In this chapter, we deployed two applications. We started the chapter by deploying the guestbook application. During that deployment, we looked into the details of Pods, ReplicaSets, and deployments. We also used dynamic configuration using ConfigMaps. Finally, we looked into how services are used to route traffic to the deployed applications.

The second application we deployed was a WordPress application. We deployed it via the Helm package manager. As part of this deployment, PVCs were used, and we explored how these were used in the system.

In the next chapter, we will look into scaling applications and the cluster itself. We will first look at the manual and automatic scaling of the application, and afterward, we'll look at the manual and automatic scaling of the cluster itself. Finally, we will explain different ways in which applications can be updated on Kubernetes.
