Description

This course is a comprehensive beginner's guide to Kubernetes. In this course, you will get a solid understanding and hands-on practical experience with Kubernetes. You will learn about key building blocks of Kubernetes: nodes, pods, services, and deployments. All you need is some basic knowledge about Docker to get started.

Kubernetes is now a de-facto standard for the deployment of the containerized applications into the production and it is the must-know tool for all DevOps engineers and software developers who want to learn how to run and test their applications in production. During this course, you will also perform practical tasks like creating a Kubernetes cluster locally on your computers using Minikube, managing the Kubernetes cluster using kubectl, creating pods, analyzing how they are assigned to nodes, and examining their internals. You will also learn to create deployments and observe how Kubernetes automatically creates necessary pods for this deployment, scale deployments, monitor deployments, and observe what happens when some of the pods fail. Furthermore, you will create services to be able to connect to the deployments both internally and externally and launch the Kubernetes dashboard. Also, in practice activities, you will learn how to deploy applications in Kubernetes following the declarative approach and you will be able to create and apply YAML configuration files for the deployments and for the services. By the end of the course, you will be able to modify deployments and services by making changes to the YAML configuration files and re-applying them.
