Summary
In this chapter, we covered some troubleshooting and debugging options, including how to control process flow. We also started to discuss which options are ideal for manual builds and which are better suited to automation, as we discuss using Packer with automation in the next chapter. While developing templates, it may be necessary to run interactive builds with prompts to answer questions or stop execution. For automation, you will need to make it non-interactive. In the next chapter, we’ll cover how that’s done.
