• Manage your applications better with Kubernetes container orchestration

Book Description

Even before the COVID-19 pandemic forced many people to work remotely, the cloud, cloud-native technologies, and cloud containers were experiencing a dramatic increase in popularity. If you're interested in this field and want to work for some of the best companies, you need to stand out from the crowd.

Becoming KCNA Certified will provide you the tools to do just that. It won't just give you the practical skills needed to deploy and connect applications in Kubernetes. It will also prepare you to pass the Kubernetes and Cloud Native Associate (KCNA) exam at the first attempt.

This book will introduce you to cloud-native computing, containers, and Kubernetes through practical examples, allowing you to test the theory out for yourself. You'll learn how to configure and provide storage for your Kubernetes-connected applications and explore the principles of modern cloud-native architecture and application delivery, giving you a well-rounded view of the subject. And once you've been through the theoretical and practical aspects of the book, you'll get the chance to test yourself with two mock exams, with explanations of the answers, so you'll be well prepared for the KCNA exam.

By the end of this book, you'll have everything you need to pass the KCNA exam and forge a career in Kubernetes and cloud-native computing.

What you will learn

• Learn about Cloud Native Computing Foundation (CNCF) and its projects
• Build, configure, and run containers with Docker
• Run an application consisting of multiple containers
• Manage and encrypt container traffic with Service Mesh
• Install, deploy, configure, and update applications on Kubernetes
• Control and connect the applications that run on Kubernetes
• Manage storage and provide observability on Kubernetes
• Automate software development with CI/CD and GitOps
