If you’ve worked in enterprise IT at any point in the past six years – either in development or operations – chances are high that you’ve crossed paths with Kubernetes, which has become the de facto standard for deploying, managing and scaling containerized applications—and for good reason. Software architecture is arguably one of the most important assets for the future of your business, and Kubernetes is the foundation for today’s hybrid cloud architectures.

Safe to say, Kubernetes plays a critical role in delivering value to your customers today and enabling you to adapt tomorrow. Keeping your skills sharp and staying up-to-date on developments around this fast-moving technology are paramount.

Kubernetes by Example (Kube by Example) is here to help. Brought to you by Red Hat, Kube By Example is a free online resource that provides a broad range of Kubernetes-focused tutorials, news and community interaction—all designed around a hands-on, "learn by doing" approach that allows learners to practice skills as they are taught.

The site originally launched in 2017, and just as the Kubernetes project has matured and grown during that time, Kube By Example has evolved as well. Today, it features a variety of learning paths teaching both the fundamentals of Kubernetes and containers, as well as topics related to application development on the platform. Developers and operators will find resources and step-by-step guides led by recognized experts on topics, including:

  • Linux Essentials
  • Command Line Essentials
  • Container Fundamentals
  • Kubernetes Fundamentals
  • Application Development on Kubernetes
  • Developing with Java on Kubernetes
  • Developing with Spring Boot on Kubernetes

The tutorials are designed to be compatible with a variety of different clusters. There are two environments to use for hands-on examples: minikube or OpenShift Playground. minikube enables you to run a single-node Kubernetes cluster on a personal computer. The OpenShift Playground provides access to a Red Hat OpenShift cluster for 60 minutes at a time. You can deploy your own container image or set up a pipeline to build an application from source.

Developers looking for more robust features can also take advantage of free OpenShift trials, such as Developer Sandbox for Red Hat OpenShift, a private OpenShift environment in a shared, multi-tenant OpenShift cluster that is pre-configured with a set of developer tools.

We’ve made it as easy as possible to access and use these tutorials. That means there are no fees to participate, or hidden "premium" content that needs to be unlocked. Simply explore the learning paths and lessons from the homepage, and when you’re ready to get started, select and configure your cluster, and you’re ready to go.

The site will also be home to a new streaming show called KBE Insider. The show will illustrate first-hand how Kubernetes is evolving and give developers insights that can help them grow in their knowledge and abilities.

The show will premiere June 29, 2021, at 10 a.m. EDT and will feature Red Hat’s Clayton Coleman, a noted developer, architect, and long time core contributor to Kubernetes. In the meantime, check out our behind the scenes look at the show and a glimpse of what’s to come in the season ahead.

As with everything we do, we are striving to make your Kubernetes learning experience easy, efficient and enjoyable. If there is anything else we can do to improve, please let us know.
