Chapter 6. Technical Kubernetes Topics
The way that applications are built and deployed today has fundamentally changed with the rise of containerization adoption, and Kubernetes is rapidly becoming the preferred solution for deploying and managing software in cloud environments. However, it presents a significant learning curve, particularly for newcomers. In this chapter, our goal is to simplify the Kubernetes landscape by providing a high-level overview of its essential components and their interactions, making it accessible to those who are just getting started.
We will explore the key components and features of Kubernetes, such as the master and worker nodes, the Pod lifecycle, the service discovery and networking mechanisms, and the security and observability tools. We will also present the concept of service mesh, a powerful technology that enhances the management and reliability of microservices architectures. In the last section, you will be provided with a list of the most used Kubernetes commands and output samples that will help you to grasp the concepts.
By the end of this chapter, you should have a solid understanding of how Kubernetes works under the hood and how it enables you to build and deploy scalable, resilient, and secure applications.
