Appendix A. Solutions to the exercises

For readers working through the exercises in this book, we want to make sure you have access to all the supporting material, whether you are reading the digital edition or holding the paperback in your hands. Throughout the chapters, we mention that the “answers” or extended walkthroughs for exercises can be found in the appendix. In practice, we have chosen to make these materials available in two reliable locations:

This shift from a static printed appendix to online resources reflects a more modern approach to learning. Instead of flipping to the back of the book and working through fixed examples, you now have direct access to a searchable, indexed, and continuously updated set of solutions and examples. The GitHub repository provides runnable code, reference implementations, and evolving samples that mirror real-world platform engineering practices. These are not just “answers,” but working artifacts you can clone, run, and adapt in your environments. The Manning site complements this by hosting downloadable PDFs for exercise solutions, as well as updates and errata, ensuring readers have a curated, official source of supporting material.
