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

As we have seen, even though defining the container's request will help with the scheduling of pods, it will not limit how much memory or CPU a container can use. Our `busybox` container was, in fact, using double the amount of CPU it requested.

We can use the `limits` property to define hard limits for these resources:

Learn how we can limit our container to use defined resources.
