Develop a deep understanding of Kubernetes and other orchestration systems by building your own with Go and the Docker API. Orchestration systems like Kubernetes can seem like a black box: you deploy to the cloud and it magically handles everything you need. That might seem perfect—until something goes wrong and you don’t know how to find and fix your problems. Build an Orchestrator in Go (From Scratch) reveals the inner workings of orchestration frameworks by guiding you through creating your own. In Build an Orchestrator in Go (From Scratch) you will learn how to: Identify the components that make up any orchestration system Schedule containers on to worker nodes Start and stop containers using the Docker API Manage a cluster of worker nodes using a simple API Work with algorithms pioneered by Google’s Borg Demystify orchestration systems like Kubernetes and Nomad Build an Orchestrator in Go (From Scratch) explains each stage of creating an orchestrator with diagrams, step-by-step instructions, and detailed Go code samples. Don’t worry if you’re not a Go expert. The book’s code is optimized for simplicity and readability, and its key concepts are easy to implement in any language. You’ll learn the foundational principles of these frameworks, and even how to manage your orchestrator with a command line interface. About the technology Orchestration frameworks like Kubernetes and Nomad radically simplify managing containerized applications. Building an orchestrator from the ground up gives you deep insight into deploying and scaling containers, clusters, pods, and other components of modern distributed systems. This book guides you step by step as you create your own orchestrator—from scratch. About the book Build an Orchestrator in Go (From Scratch) gives you an inside-out perspective on orchestration frameworks and the low-level operation of distributed containerized applications. It takes you on a fascinating journey building a simple-but-useful orchestrator using the Docker API and Go SDK. As you go, you’ll get a guru-level understanding of Kubernetes, along with a pattern you can follow when you need to create your own custom orchestration solutions. What's inside Schedule containers on worker nodes Start and stop containers using the Docker API Manage a cluster of worker nodes using a simple API Work with algorithms pioneered by Google’s Borg About the reader For software engineers, operations professionals, and SREs. This book’s simple Go code is accessible to all programmers. About the author Tim Boring has 20+ years of experience in software engineering. For most of that time he has worked with orchestration systems, including Borg, Kubernetes, and Nomad.

Written by the chief military correspondent of the New York Times and a prominent retired Marine general, this is the definitive account of the invasion of Iraq. A stunning work of investigative journalism, Cobra II describes in riveting detail how the American rush to Baghdad provided the opportunity for the virulent insurgency that followed. As Gordon and Trainor show, the brutal aftermath was not inevitable and was a surprise to the generals on both sides. Based on access to unseen documents and exclusive interviews with the men and women at the heart of the war, Cobra II provides firsthand accounts of the fighting on the ground and the high-level planning behind the scenes. Now with a new afterword that addresses what transpired after the fateful events of the summer of 2003, this is a peerless re-creation and analysis of the central event of our times.

"The Cobra Civil War is over but there's no risk of a peace outbreak. 'Cobra Command' begins as Krake, the new Cobra Commander, kicks off his reign with total war as he invades the sovereign nation of Nanzhao with all the military might under his power. While the JOEs have been hit hard Flint must still lead a team into the country to stop them."--Page 4 of cover.

The American Villain: Encyclopedia of Bad Guys in Comics, Film, and Television seeks to provide one go-to reference for the study of the most popular and iconic villains in American popular culture. Since the 1980s, pop culture has focused on what makes a villain a villain. The Joker, Darth Vader, and Hannibal Lecter have all been placed under the microscope to get to the origins of their villainy. Additionally, such bad guys as Angelus from Buffy the Vampire Slayer and Barnabas Collins from Dark Shadows have emphasized the desire for redemption—in even the darkest of villains. Various incarnations of Lucifer/Satan have even gone so far as to explore the very foundations of what we consider "evil." The American Villain: Encyclopedia of Bad Guys in Comics, Film, and Television seeks to collect all of those stories into one comprehensive volume. The volume opens with essays about villains in popular culture, followed by 100 A–Z entries on the most notorious bad guys in film, comics, and more. Sidebars highlight ancillary points of interest, such as authors, creators, and tropes that illuminate the motives of various villains. A glossary of key terms and a bibliography provide students with resources to continue their study of what makes the "baddest" among us so bad.
