We took a look at the overall architecture for Kubernetes, as well as the core constructs, provided to build your services and application stacks. You should have a better understanding of how these abstractions make it easier to manage the life cycle of your stack and/or services as a whole and not just the individual components. Additionally, we took a first-hand look at how to manage some simple day-to-day tasks using pods, services, and replication controllers. We also looked at how to use Kubernetes to automatically respond to outages via health checks. Finally, we explored the Kubernetes scheduler and some of the constraints users can specify to influence scheduling placement.
In the next chapter, we will dive into the networking layer of Kubernetes. We'll see how networking is done and also look at the core Kubernetes proxy that is used for traffic routing. We will also look at service discovery and the logical namespace groupings.
