Preface
With so many IT management and DevOps tools on the market, both open source and commercial, it's difficult to know where to start. DevOps is incredibly powerful when implemented correctly, here's how to get it done.
What this learning path covers
Module 1, Puppet Cookbook (third edition), this module covers all aspects of your puppet infrastructure using simple easy to follow recipes that are independent and can be used to solve real world problems quickly.
Puppet Cookbook takes the reader from a basic knowledge of Puppet to a complete and expert understanding of Puppet's latest and most advanced features. With emphasis on real-world implementation, this book delves into various aspects of writing good Puppet code, including using Puppet community style, checking your manifests with puppet-lint and community best practices. It then shows the readers how to set up Puppet for the first time, including instructions on installing Puppet, creating your first manifests, using version control with Puppet and so on. You will also learn to write better manifests, manage resources, files and applications. You'll then be introduced to powerful tools that have grown up around Puppet, including Hiera, Facter, and rspec-puppet. Finally, you will also learn to master common Monitoring, Reporting, and Troubleshooting techniques.
Updated with the latest advancements and best practices, this book gives you a clear view on how to "connect the dots" and expands your understanding to successfully use and extend Puppet.
Module 2, Docker Cookbook, this module aims to help you get working with Docker by providing you with step-by-step recipes that enable you to effectively deploy Docker in your development, test, and production environments.
You will start with verifying and installing Docker on different environments and look into understanding and working with containers and images. Next, you will move on to study the operations related to images. You then proceed to learn about network and data management for containers and how to build an environment for Continuous Integration with the help of services from companies like Shippable and Drone. The book then explores the RESTful APIs provided by Docker to perform different operations like image/container operations before taking a look at the Docker Remote API client. The book ends with a look at logs and troubleshooting Docker to solve issues and bottlenecks.
Module 3, Kubernetes Cookbook, Kubernetes is Google's solution to managing a cluster of containers. Kubernetes provides a declarative API to manage clusters while giving us a lot of flexibility. This book will provide you with recipes to better manage containers in different scenarios in production using Kubernetes.
We will start by giving you a quick brush up on how Kubernetes works with containers along with an overview of the main Kubernetes features such as Pods, Replication Controllers, and more. Next, we will teach you how to create Kubernetes cluster and how to run programs on Kubernetes. We'll explain features such as High Availability Kubernetes master setup, using Kubernetes with Docker, and orchestration with Kubernetes using AWS. Later, will show you how to use Kubernetes-UI, and how to set up and manage Kubernetes clusters on the cloud and bare metal.
Upon completion of this book, you will be able use Kubernetes in production and will have a better understanding of how to manage your containers using Kubernetes.
