Deployment with Docker

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.

Chapter 5. Keeping the Data Persistent

In this chapter, we will cover how to keep your important data persistent, safe, and independent of your containers by covering everything about Docker volumes. We will go through various topics, including the following:

  • Docker image internals
  • Deploying your own instance of a repository
  • Transient storage
  • Persistent storage
    • Bind-mounts
    • Named volumes
    • Relocatable volumes
  • User and group ID handling

While we won't cover all the available storage options, especially ones that are specific to orchestration tooling, this chapter should give you a better understanding of how Docker handles data and what you can do to make sure it is kept in exactly the way you want it.
