Summary
In this chapter, we learned that Pods are the most basic building block we have to work with in Kubernetes. It's important to have a strong understanding of Pods and all their subtleties because all compute on Kubernetes uses Pods as a building block. It's probably pretty obvious by now, but Pods are very small, individual things that are not very sturdy. Running an application as a single Pod on Kubernetes with no controller is a bad decision, and any issue with your Pod will result in downtime.
In the next chapter, we'll see how to prevent this by using Pod controllers to run multiple replicas of an application at once.
