Jump right into Kubernetes development with career-focused lessons and hands-on practice.

DevOps for Developers

Kubernetes is a powerful container management tool that's taking the world by storm. This detailed course will help you master it.

In this course, you'll start with the fundamentals of Kubernetes and what the main components of a cluster look like. You'll then learn how to use those components to build, test, deploy, and upgrade applications, as well as how to achieve state persistence once your application is deployed. You'll also learn how to secure your deployments and manage resources, which are crucial DevOps skills.

By the time you're done, you'll have a firm grasp on what Kubernetes is, as well as the skills to deploy your own clusters and applications with confidence.

A Practical Guide to Kubernetes

# Summary

Everything we learned led us to Deployments. Pods must not be created directly, but through ReplicaSets which, similarly, must not be created directly, but through Deployments. They are the objects that allow us not only to create the ReplicaSets and Pods, but that can also be updated without producing any downtime (when applications are designed accordingly). 

We combine Deployments with Services so that Pods can communicate with each other and be accessed from outside a cluster. All in all, we have everything we need to release our Services to production. That is not to say that we understand all the crucial aspects of Kubernetes. We’re not even close to that point. However, we do have almost everything we need to run some types of applications in production. What we’re missing now is just networking.
