Kubernetes is a one of the top cloud platform technology and offers some of the best solution over other cloud platforms. Major cloud infrastructure providers, such as AWS, Azure, and Google, offer hosted versions of Kubernetes.
This comprehensive 2-in-1 training course provides in-depth learning of core components and concepts, followed by hands-on experience installing and managing Kubernetes.
Furthermore, the course will intrigue you with deploying an app to a local Kubernetes installation, as well as an overview of best practices for deploying app models to Kubernetes.

Contents and Overview
This training program includes 2 complete courses, carefully chosen to give you the most comprehensive training possible.
The first course, Learning Kubernetes, gives you a hands-on experience in installing Kubernetes on your personal computers. See how to extend the opportunities that containerization innovations have brought about in a new and even more effective way. You will then get started with the basics, explore the fundamental elements of Kubernetes, and find out how to install it on your system, before digging a little deeper into Kubernetes core constructs. Finally, you will learn how to use Kubernetes pods, services, replication controllers, and labels to manage your clusters effectively and also get a feel for how to handle networking with Kubernetes.
The second course, Deploying Software to Kubernetes, starts by explaining the organizational alignment that has to happen in every company that wants to implement DevOps in order to be effective. We delve into deploying and managing applications on Kubernetes, but we also take a look at how Docker Swarm works. We also explore how to create a continuous delivery pipeline and deploy a microservice-based system to update it, keeping all the lights on. We will review some tools for monitoring software, but our focus will be on Stackdriver, as this monitoring solution from Google Cloud Platform provides us (out of the box) with a fairly comprehensive set of tools to deal with the flaws in our systems.
By the end of this Learning Path, you’ll have acquired all the skills and a deeper insight into deploying software on Kubernetes and deliver results from day 1.
