Description:
***[CNCF Endorsed] ***Student Testimonials -★★★★★ "This was not the first Kubernetes course I enrolled in. After completing the others, I felt like I was missing the details; like I could work with a K8s Cluster as long as everything is in great shape. But if the slightest gear would crack (which likely may happen, especially when updating K8s), I felt like I did not even have a clue where to start looking at. This course filled the majority of these knowledge gaps for me and I am very happy that I have enrolled in this! Wish this were my first K8s course before enrolling in the others"★★★★★ "Amazing! I especially like the part on dissecting the various components of Kubernetes: shut down all the components and starting them one by one to see what each of them does. It gives me a good understanding of how Kubernetes works under the hood. The explanations and demos are also concise and clear. Not to mention the convenient and awesome lab environment. Thank you James for this awesome course!"★★★★★ "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!"★★★★★ "Excellent course for those who want to learn basics of Docker and well explained Kubernetes basic concepts including its architecture. Quiz section is just good to evaluate your knowledge and Lab Challenge contains exercise which if you complete properly then you will become confident in Container and Kubernetes concepts."★★★★★ "Clear information, spoken and visual. The content covers a lot of question, the tone is perfect with enough space to be able to follow without replaying any section. I'm delighted."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 Kubernetes ArchitectureMy 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!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.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.
Who this course is for:
Beginners in Containers
System Administrators
Developers
Operations
Technical Project Managers
Users of Docker looking to make the next step into Kubernetes
