Learn Kubernetes & Docker - .NET Core, Java, Node.JS, PHP or Python
Learn Kubernetes & Docker - .NET Core, Java, Node.JS, PHP or Python
Be ready to create and run your containerized and orchestrated application next week.
About the Book
This book is for anyone who needs to run software using Docker and orchestrate it on Kubernetes. Whether you’re a developer, a DevOps manager or a technician, this book should help you create Docker containers then plan and run them as 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 and Docker 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 and Docker, 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 as Docker containers on your machine then on a Kubernetes cluster.
Read this book, and you can create and run your first Kubernetes application within a week. Or your money back.
This book is a combination of Learn Docker and Learn Kubernetes books so that you can save time and money in case you are interested in both subjects.
