SirM Aug 31, 2019

One can tell from introduction going forward the author did not in anyway rely much on readers feedback from previous edition thus you have the same introductory formula in writing style applied. The author assumes the readers somehow have an ideal setup like he does whereby when using vagrant you have ssh issues, does not indicate whether he uses global or local inventory file and thus you have to fill-in the gaps via google search. Literally the material is hard to digest thus a greater balance of understanding will depend on the user investing their time on official ansible docs. A half baked effort that is not engaging, could have been better.

I bought the book since this is fairly recent, ansible 2.9 is the current version. I first considered ansible up and running from O'Reilly Press but that book is a little bit aged and reviews said that it great but it should be updated to a new edition soon. This is why I landed on this book. Unfortunately, I feel I learned not a whole lot from this book. The Author is giving examples but is failing to explain these. Or I was unable to follow as good. Also, the author is half helping with the vagrant setup, It took me a couple of hours to have a working environment with vagrant since I had to research a whole bunch. I would have liked a better thought through examples. In fact, after this book, I have read the extract from ansible up and running which is containing the first two chapters. Which explained vagrant in a far better way and how I can get started.I am missing for whom this book is written because I feel the examples are really basic but the missing of explanations I would assume it's for more advanced users. I guess this book is missing some kind of clear concept. Sometimes the Author is touching onto topics that seem completely out of place at that moment.I recently purchased jeff Geerling's Ansible for DevOps ebook which is regularly updated so it is really current, and it fits me a lot more. Since the Author is really clear about what he is trying to achieve.Unfortunately, I missed the date to give the kindle version back of this book.

Where can I send feedback about an Early Access title?

If you have any feedback about the product you're reading, or Early Access in general, then please fill out a contact form here and we'll make sure the feedback gets to the right team.

Can I download the code files for Early Access titles?

We try to ensure that all books in Early Access have code available to use, download, and fork on GitHub. This helps us be more agile in the development of the book, and helps keep the often changing code base of new versions and new technologies as up to date as possible. Unfortunately, however, there will be rare cases when it is not possible for us to have downloadable code samples available until publication.

When we publish the book, the code files will also be available to download from the Packt website.

How accurate is the publication date?

The publication date is as accurate as we can be at any point in the project. Unfortunately, delays can happen. Often those delays are out of our control, such as changes to the technology code base or delays in the tech release. We do our best to give you an accurate estimate of the publication date at any given time, and as more chapters are delivered, the more accurate the delivery date will become.

How will I know when new chapters are ready?

We'll let you know every time there has been an update to a course that you've bought in Early Access. You'll get an email to let you know there has been a new chapter, or a change to a previous chapter. The new chapters are automatically added to your account, so you can also check back there any time you're ready and download or read them online.

I am a Packt subscriber, do I get Early Access?

Yes, all Early Access content is fully available through your subscription. You will need to have a paid for or active trial subscription in order to access all titles.

How do I buy Early Access content?

Early Access is a way of us getting our content to you quicker, but the method of buying the Early Access course is still the same. Just find the course you want to buy, go through the check-out steps, and you’ll get a confirmation email from us with information and a link to the relevant Early Access courses.

What is Early Access?

Keeping up to date with the latest technology is difficult; new versions, new frameworks, new techniques. This feature gives you a head-start to our content, as it's being created. With Early Access you'll receive each chapter as it's written, and get regular updates throughout the product's development, as well as the final course as soon as it's ready.We created Early Access as a means of giving you the information you need, as soon as it's available. As we go through the process of developing a course, 99% of it can be ready but we can't publish until that last 1% falls in to place. Early Access helps to unlock the potential of our content early, to help you start your learning when you need it most. You not only get access to every chapter as it's delivered, edited, and updated, but you'll also get the finalized, DRM-free product to download in any format you want when it's published. As a member of Packt, you'll also be eligible for our exclusive offers, including a free course every day, and discounts on new and popular titles.
