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 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.

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.
