In this chapter, you learned how to build a Helm chart from scratch by writing a chart to deploy the Guestbook application. You began by creating a chart that deployed the Guestbook frontend and a Redis dependency chart, and you later improved upon this chart by writing life cycle hooks and adding input validation. You concluded this chapter by building your own chart repository with GitHub Pages and publishing your
guestbook chart to this location.
In the next chapter, you will learn strategies around testing and debugging a Helm chart, to enable you to further strengthen your chart development skills.
