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.

Summary


In this chapter, we have learned many advanced tools and techniques needed to deploy robust clusters, such as the following:

  • Additional debugging options to manage container issues.
  • Deep dives into Docker's advanced networking topics.
  • Implementing our own queue messaging.
  • Various security hardening tips and tricks.

All of these topics combined with previous material should cover the gamut of deployment needs for most clusters. But in the next chapter, we will see what issues we need to worry about when the number of hosts, services, and tasks reaches levels that aren't generally expected and we start seeing the clusters fall apart and what we can do to mitigate such problems.
