Summary
In this chapter, we branched out from having a single large Packer template to having a structured tree of images. We also added some container images to our tree for applications. We now have base system images, application system images, and container images all in one strategy. We set ourselves up for some basic automation and bulk-building images. We are still running Packer manually though and have not added automation pipelines.
In the next chapter, we will expand on automation and implement full pipelines to trigger builds based on code changes and event triggers. This is where Packer shines and becomes collaborative as teams can contribute to different parts of template code.
