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 is Early Access delivered?

Early Access is currently only available as a PDF or through our online reader. As we make changes or add new chapters, the files in your Packt account will be updated so you can download them again or view them online immediately.

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.

If you’ve done any coding since roughly 2005, you have probably used Git to manage development and production. “DevOps Unleashed with Git and GitHub” (Packt, 2024) by Yuki Hattori works hard to bring veteran developers up to speed on the new tools. The book includes extensive coding samples, various development strategies, and thoroughly explores the benefits, challenges, and best practices for each approach. A quick read: the book is divided into three sections, starting with Git, excellence in practices, and beyond DevOps. This book makes an excellent reference for developers, system administrators, or project managers who are currently using GitHub. The book begins with a fresh introduction to Git from the command-line perspective, exploring structures, commands and usages. This brings the reader in at a basic level and ensures a familiarity with the approach. One interesting term, and a first for me, was InnerSource, the development tied to a team rather than OpenSource, where all code becomes widely available. InnerSource pillars are described as openness, transparency, prioritizing mentorship, and voluntary code contribution. The second section moves from the command line git to the user interface (UI) associated with GitHub. These reinforce the techniques from the first section with a point-and-click rather than a command-line approach. One of the best parts for me was the thorough overview of GitHub Issues and Projects. If you haven’t used these tools, they address a historical weakness in GitHub with being able to create work to be done and track via a Scrum or Kanban board. The section also covers establishing a GitHub actions pipeline and describes various deployments such as Blue/Green, A/B, canary, feature flags, and others in detail. Like all other actions, these approaches include benefits, challenges, and best practices to take away. Finally, the book discusses DevOps metrics with DORA and Space, and introduces the concept of Ai. GitHub Copilot, as an additional coding tool. Copilot launched in late 2021 and provides an assistant to writing code. The author references some key aspects when using AI such as detailed comments, descriptive naming conventions, thorough documentation and clearly framed problems. While one may prefer using Generative AI, simply telling it to write code to do a thing doesn’t always get the best results. My biggest issue was the DevOps portion fell a little short. The first chapter extensively covers some of the logic around DevOps, and emphasizes the cultural nature. I agree culture is the primary aspect of DevOps, but if culture is the driver, than technology becomes less important. The book’s DevOps approach feels more like framing to showcase Git and GitHub rather than a full unleashing. In full DevOps implementation, the tools matter, but people and processes carry equal weight. Tools also are a needed element but not an exclusive element to reach accelerated delivery. The DevOps SDLC appears, but the three ways of flow, feedback, and continuous improvement and the CALMS (culture, automation, Lean, Metrics, and Sharing) are conspicuously absent. Agood example might be rather than simply mentioning how Git supports DevOps, show what a full unleashing looks like to the author. Overall, “Devops Unleashed with Git and GitHub” does a much better job in describing the tools than truly unleashing DevOps. That said, this is an excellent reference for those using Git or GitHub for their current development needs. If you are working with either of those tools, I recommend this as a reference and a good introduction to some new capabilities. If you are just starting into coding, this is an excellent place to pick up some core skills.

Has a good review on Git and DevOps practices, but you have to wade through a lot of extra words on the page. Could have been much more succinct and would have appreciated leaning more towards nuts and bolts technical detail.
