Deployment with Docker

By: Srdjan Grubor

Overview of this book

Deploying Docker into production is considered to be one of the major pain points in developing large-scale infrastructures, and the documentation available online leaves a lot to be desired. With this book, you will learn everything you wanted to know to effectively scale your deployments globally and build a resilient, scalable, and containerized cloud platform for your own use. The book starts by introducing you to the containerization ecosystem with some concrete and easy-to-digest examples; after that, you will delve into examples of launching multiple instances of the same container. From there, you will cover orchestration, multi-node setups, volumes, and almost every relevant component of this new approach to deploying services. Using intertwined approaches, the book will cover battle-tested tooling, or issues likely to be encountered in real-world scenarios, in detail. You will also learn about the other supporting components required for a true PaaS deployment and discover common options to tie the whole infrastructure together. At the end of the book, you learn to build a small, but functional, PaaS (to appreciate the power of the containerized service approach) and continue to explore real-world approaches to implementing even larger global-scale services.

Pitfall avoidance

In most small and medium deployments, you will never see the same problems that you will start seeing when you scale up beyond them, so this section is to show you the most common issues that you will encounter and how to work around them in the cleanest way possible. While this list should cover most of the glaring issues you will encounter, some of your own will need custom fixes. You shouldn't be scared to make those changes because almost all host OS installations are just not geared towards the configuration that a high-load multi-container would need.


WARNING! Many of the values and tweaks in this section have been based on personal experiences with deploying Docker clusters in the cloud. Depending on your combination of cloud provider, OS distribution, and infrastructure-specific configurations, the values may not need changing from the defaults, and some may even be detrimental to your system if used verbatim without spending some time learning what they mean...
