We have just completed the tenth and final chapter of this book. This chapter focused on the most common issues that I, and the people I work with, regularly encounter with Puppet. We learned how to identify and rectify the node definition issues. We also looked at how to work around duplicate declaration and dependency cycle errors as well as what to do when Puppet reports resources are not found. Finally, we created a Puppet Agent certificate problem and learned how to fix it by regenerating the certificate signing request.

I hope you enjoyed this final chapter as well as the overall book.

Thanks!
