Description
The videos in the course has been created using different concept. We have taken screenshots of step by step implementation of various Kubernetes concepts. From those screenshots, we have created course videos. Please remember that creating course using this approach took significant more time that otherwise would have taken. Now question arises why we have taken this approach?Kubernetes is a complex concept involving many components. Understanding how these components work individually and in combination is necessary for understanding Kubernetes. For understanding complex relation among different building blocks of Kubernetes, creation of high quality diagrams is must.
In this course, we have created 3 node Kubernetes cluster using three virtual machines (VMs). Now when we create pods (using Pod, ReplicaSet, Deployment, DaemonSet objects), these are given unique IP address, name and scheduled on nodes dynamically. So when we first took screenshots, we were able to create exact diagrams based on IP, Name, Node allocated. After that we created course videos. Same is true when we talk about Kubernetes service object.
We have checked the effectiveness of this approach many times when taking online classes. This approach was very effective in making people understand Kubernetes properly.
If you are not convinced about the effectiveness of this approach, then we will suggest that this course is not for you. The following will be covered
