Kubernetes is the hottest topics in the realm of DevOps and is one of the most demanded skillsets. As a DevOps Engineer, salaries upwards of $100,000 annually are readily available.
This course fully takes you from ground zero! You'll learn the basics of Containers. You'll learn how to become effective with Docker (how to use Docker to run, manage and even build multi platform containers!). We'll then focus on Kubernetes and by the end of this course you'll also have a solid foundation of Kubernetes and every component that is used.
Provided with this course is an incredible lab environment that will enforce all knowledge in the course as well as quizzes, optional study and optional challenges!
This course was created based on my own personal frustrations when learning Kubernetes. Many courses and books explain the core components as theory but have little hands on usage or examples of the architectural components.
⭐⭐⭐⭐⭐ "Brilliant concise course. I needed a refresher to Kubernetes architectural fundamentals and this was perfect. It is a very engaging and well designed course, with great visuals (e.g. the indicator lines superimposed on terminal text, the smooth scrolling, the diagrams etc). I thought using a one node cluster might make things more confusing but actually it made it much easier and I liked the way things came full circle at the end. Highly recommend this for newcomers to Kubernetes or those like me who need a refresher in the fundamentals" - Student Testimonial
My belief is that an understanding of the Kubernetes core components, as well as those that are hidden in the background provides you with a much better understanding of how and why Kubernetes works and will also make you more much effective with Kubernetes!
⭐⭐⭐⭐⭐ "The course is direct to the point in terms of it being hands-on. You are practically taken through the installations and finally, an outline of the entire deep-dive is shared for better understanding. Also, the quiz and challenges section is detailed in such a way that it would offer one a comprehensive review of the entire course. Great!" - Student Testimonial
After an overview of the history of Containers, Kubernetes and the relationship to Docker, we'll cover the use of Dockershim, it's deprecation, the inception of Containerd and Runc and we'll configure these as part of our container runtime environment.
We'll then install and configure Nerdctl, a cli for Containerd that provides the awesome CLI experience that we're used to with Docker!
CNI plugins provide an introduction to the world of Container Network Interfaces.
We'll build a Kubernetes cluster using kubeadm and explore common components and functionality - Pods, the Pause container, Deployments, Replicasets and Services.
With our Kubernetes cluster running, we'll carefully dismantle the components one by one. We'll then start each component, repeating the functionality that we've explored and will understand, step by step, what each component is and why it's important in the Kubernetes ecosystem.
⭐⭐⭐⭐⭐ "Great video for kickstarting with k8s. Thanks, James, same as the Ansible course, the videos are super clean and organized" - Student Testimonial
We'll talk through the use of the Kubelet, ETCD, Kube-ApiServer, Kube-Scheduler, Controller-Manager, Kube-Proxy, CoreDNS and Kube-DNS!
Lastly there are Quizzes and Challenges to test and take your knowledge further.
