Dan Pirvanescu Feb 05, 2022

A very good book. Good explanations, good examples, complete. Anyway requires little effort to adapt to the new release of Ansible, but works. I recommend it. I just succeeded the Cisco CCNA exam and helped me preparing the CCNP.

For what I have read so far, it's been great. But, I keep running into "Beyond the scope of this book". It's MASTERING Ansible. When would be a better time to put the information in the book ?Mastering Ansible...The stuff we felt that was beyond the other book.

Pyers Jul 07, 2020

This might be the best book on Ansible ever written but I can't tell because the production values are so poor. A lot of the book consists of screen caps that are reproduced in black and white. Fine except that the images come out so poorly. Text is fuzzy and unclear, light grey on a dark grey background making it very difficult to read and even more to follow. It might be a superb book but I just cannot tell.
