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.

It’s a key part of DevOps practices and enables fast, repeatable, and reliable testing and deployment. It also gives developers more time to work on features and fixes. The automated steps are often referred to as a pipeline.
Continuous integration (CI)
CI is focussed on automating software builds and tests. A developer will typically merge code to a repo with a particular tag that kicks-off an automated pipeline that builds the software and runs tests against it. It’s common to spin-up the build in a container and perform the tests. The code that passes the tests gets passed on to later CD stages.
Continuous delivery (CD)
CD is focussed on automating the delivery of software and infrastructure to live environments. It typically runs after CI processes and only deploys “...
