And on Linux, you can bypass the entire hypervisor layer by using Docker directly. It was developed by Google using the Go Programming Language, and this amazing technology has been open-source since 2014. According to the Stack Overflow Developer Survey - 2020, Kubernetes is the 3 most loved platform and 3 most wanted platform. Apart from being very powerful, Kubernetes is known as quite hard to get started with. I wont say its easy, but if you are equipped with the prerequisites and go through this guide attentively and with patience, you should be able to: Get a solid understanding of the fundamentals. Prerequisites Familiarity with JavaScript Familiarity with the Linux Terminal Familiarity with Docker (suggested read: The Docker Handbook ) Project Code Code for the example projects can be found in the following repository: fhsinchykubernetes-handbook-projects Project codes used in The Kubernetes Handbook:notebook: - fhsinchykubernetes-handbook-projects fhsinchy GitHub Spare a to keep me motivated You can find the complete code in the k8s branch. It can be used in any environment where you use containers and can help you deploy the same application across different environments without requiring any redesigning. Assume that you have developed an amazing application that suggests to people what they should eat depending on the time of day. Now assume that youve containerized the application using Docker and deployed it on AWS. If the application goes down for any reason, the users lose access to your service immediately. To solve this issue, you can make multiple copies or replicas of the same application and make it highly available. Even if one of the instances goes down, the other two will be available to the users. Now assume that your application has become wildly popular among the night owls and your servers are being flooded with requests at night, while youre sleeping. What if all the instances go down due to overload Whos going to do the scaling Even if you scale up and make 50 replicas of your application, whos going to check on their health How are going to set-up the networking so that requests hit the right endpoint Load balancing is going to be a big concern as well, isnt it Kubernetes can make things much easier for these kinds of situations. ![]() Assume that you want to have 50 replicas of your application running continuously. Even if there is a sudden rise in the user count, the server needs to be scaled up automatically. You just tell your needs to Kubernetes and it will do the rest of the heavy lifting for you. Kubernetes will not only implement the state, itll also maintain it. ![]() To get Kubernetes up and running, you need two programs. Kubernetes cluster inside a Virtual Machine (VM) on your local computer. Docker is the obvious choice for the containerization platform. Recommended hypervisors are as follows: Hyper-V for Windows HyperKit for Mac Docker for Linux Hyper-V comes built into Windows 10 (Pro, Enterprise, and Education) as an optional feature and can be turned on from the control panel. HyperKit comes bundled with Docker Desktop for Mac as a core component.
