Kubernetes Essentials

“Kubernetes in Practice” is our one-stop shop to learn how to build, deploy, scale, and manage Kubernetes with a step-by-step process.

We'll explore key concepts of Kubernetes with hands-on practice, including architecture, pods, deployments, services, and Ingress. Once the fundamentals are out of our way, we can put your skills to work. We’ll do this through a project where we will create and run an application in a real Kubernetes cluster.

By the time we finish this module, you will have complete confidence in our deployment and management of Kubernetes clusters.

Kubernetes in Practice

Let’s look back and see what we have learned in this chapter.


* Containers without resource limits can affect other applications sharing the same worker node.
* We can define a resource request so Kubernetes will only schedule a pod in a worker node that can fulfill that request.


* Containers can use more resources than they requested.
