Learn Kubernetes - Container orchestration using Docker
Learn Kubernetes - Container orchestration using Docker
Be ready to create and run your orchestrated application next week.
About the Book
This book is for anyone who needs to run software on Kubernetes. Whether you’re a developer, a DevOps manager or a technician, this book should help you plan and run Kubernetes workloads.
I assume that you have no previous knowledge about containers or containers orchestration.
I made my best to keep this book small, so that you can learn Kubernetes quickly without getting lost in petty details. If you are looking for a reference book where you’ll find answers to all the questions you may have within the next 4 years of your Kubernetes practice, you’ll find other heavy books for that. My purpose is to swiftly provide you with the tools you need to create and run your first cloud-ready application using Kubernetes, then be able to look for more by yourself when needed.
Plus this book is packed with exercises and samples where you create, run and manage your own applications on a Kubernetes cluster.
Read this book, and you can create and run your first Kubernetes application within a week. Or your money back.
