Overview of this book

There is a huge benefit in building small, specialized, single-purpose apps that can self-heal, auto scale, and update regularly without needing downtime. Kubernetes and cloud-native technologies come in handy in building such apps. Possessing the knowledge and skills to leverage Kubernetes can positively enhance possibilities in favor of architects who specialize in cloud-native microservices applications. ‘The KCNA Book’ is designed to help those working in technology with a passion to become certified in the Kubernetes and Cloud-Native Associate Exam. You will learn about containerization, microservices, and cloud-native architecture. You will learn about Kubernetes fundamentals and container orchestration. The book also sheds light on cloud-native application delivery and observability. It focuses on the KCNA exam domains and competencies, which can be applied to the sample test included in the book. Put your knowledge to the test and enhance your skills with the all-encompassing topic coverage. Upon completion, you will begin your journey to get the best roles, projects, and organizations with this exam-oriented book.

Primer

Cloud native application delivery is often referred to as code to cloud and code to production, and we usually automate it with continuous integration (CI) and continuous delivery (CD) pipelines as well as GitOps tools. We’ll talk more about all of this later in the chapter, but for now you should know the major automation steps.

  1. Build code
  2. Test code
  3. Release code

Automating these steps enables fast, frequent, and high-quality releases.

Finally, release is jargon for rolling out a new version of an application or an environment. For example, updating an application from version 1.1 to version 1.2 is accomplished via a release. We often use the terms rollout, update, and release to mean the same thing.
