Summary

This chapter gave a very high-level overview of the HashiCorp tool called Packer. It’s actually a very simple tool that delivers powerful results when working with image management at any scale. As a tool, Packer is used when needed rather than as a service that listens for tasks. You can build templates that deliver flexible, scalable, standardized images around the world or in your own private data center. We’ve explored a few basic sample templates, but the best way to learn how Packer works is to jump in with building your first template, which we’ll cover in the next chapter.
