Description

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 Architecture

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!

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
