Summary

This brings us to the end of our journey to understanding Ohai and its plugin ecosystem. We learned about Ohai and its associated plugins and went on to develop our own custom plugin. We learned about how to make use of the Ohai DSL and how Ohai is used by chef-client to fetch information about the concerned node. In the next chapter, we are going to learn about data bags and templates in detail and how they can make your life easier.
