Now, you should have a good foundation of the core constructs in Kubernetes. We explored the new Deployment abstraction and how it improves on the basic ReplicationController, allowing for smooth updates and solid integration with services and autoscaling. We also looked at other types of workload in jobs and DaemonSets. You learned how to run short-running or batch tasks, as well as how to run agents on every node in our cluster. Finally, we took a brief look at node selection and how that can be used to filter the nodes in the cluster used for our workloads.

We will build on what you learned in this chapter and look at stateful applications in the next chapter, exploring both critical application components and the data itself.
