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. 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, For software engineers, operations professionals, and SREs. This book's simple Go code is accessible to all programmers.
