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.

Installing Docker

The installation of Docker varies greatly between operating systems, but for most systems, there are detailed instructions at Two levels of Docker are generally available: the Community Edition (CE) and the Enterprise Edition (EE). While slightly different, for almost everything that we will work on in this book, the Community Edition is perfectly functional and will suffice in every way. Once you reach levels of scale where you need much more advanced features, such as security scans, LDAP, and technical support, the Enterprise Edition might make sense. As would be expected, the Enterprise Edition is not free, and you can take a look at to see how these editions differ.

For our examples and any OS-specific commands in this book, from here on, we will be using Ubuntu's Long Term Support (LTS) version, with Ubuntu being currently the most popular Linux distribution. The latest version of the LTS...
