Summary

In this chapter, we journeyed through various methods available for launching pods in Kubernetes. It’s crucial to grasp that a pod is the smallest deployable unit in Kubernetes, confined to a single node. Yet, the true power of Kubernetes is unlocked when we manage multiple pods, and we uncovered eight distinct ways to achieve this.

We started with the basics of pod creation, moved on to ReplicaSets and Deployments for managing stateless applications, and then to StatefulSets for those requiring persistent storage. We explored DaemonSets for node-wide services and Jobs and CronJobs for task scheduling. We also touched upon the self-cleaning mechanism provided by TTL and the direct node-level management of Static Pods.

While we covered fundamental aspects of pod deployment, we intentionally paused before discussing scaling strategies, such as how ReplicaSets and Deployments can adjust the number of pod instances. This sets the stage for our next chapter, where...
