Summary: Running an Application on Kubernetes

Recap

In this chapter, we learned that containerized apps must be wrapped in Pods if they want to run on Kubernetes. Fortunately, Pods are lightweight constructs that add no overhead.

We saw a simple Pod defined in a YAML file and learned how to deploy it to Kubernetes with the kubectl apply command. We also learned how to inspect objects with kubectl get and kubectl describe.

Finally, we learned that Kubernetes Services allows us to connect to apps running in Pods.

So far, we’ve built, deployed, and connected to a containerized app. However, we haven’t seen self-healing, scaling, or any other cloud native features. We’ll discuss all of these in the upcoming chapters.
