Summary
In this chapter, you deployed two applications. You started the chapter by deploying the guestbook application. During that deployment, the details of pods, ReplicaSets, and deployments were explored. You also used dynamic configuration using ConfigMaps. Finally, you looked into how services are used to route traffic to the deployed applications.
The second application you deployed was a WordPress application. You deployed it via the Helm package manager. As part of this deployment, PVCs were used, and you explored how they were used in the system and how they were linked to disks on Azure.
In Chapter 4, Building scalable applications, you will look into scaling applications and the cluster itself. You will first learn about the manual and automatic scaling of the application, and afterward, you'll learn about the manual and automatic scaling of the cluster itself. Finally, different ways in which applications can be updated on Kubernetes will be explained.
