Thank you Eldad! JFrog rules the world. This book brought me up to speed from novice to expert in kubernetes and container management. It's easy to read, understand and apply the knowledge to simple and complex DevOps solutions. I'm very happy I came across this book after going through many such books on the topic. Thank you again for excellent work!

I highly recommend this new book by Rimantas Mocevicius. Finally a good book on the Swiss army knife, kubectl, for k8s with good examples. The first 6 chapters shows all about kubectl and how to do this and that with kubectl. Although we will often do declarative deployments. It is still important to know how to do things imperatively, e.g. k drain/cordon a problematic node, describe this and that k8s objects, k rollout undo/status/history, etc... It shows many real life kubectl on cloud examples with GCP GKE.I like Chapter 7 most because it shows how we can extend kubectl with plugins, e.g. how to use Krew to find and install plugins, then you can use "k really get all" plugin, k view-allocations, etc. It then teaches how to create your own simple plugin.Chapter 8 teaches Kustomize and how to use it to deploy with overlays.Chapter 9 is another favorite, Helm! Rimantas knows this very well because he is a co-author of Helm."Helm is the de facto Kubernetes package manager, and one of the best and easiest ways to install any kind of complex application on Kubernetes." (p. 93 of the book).He walks the readers step by step in Helm and how to use it to helm install, upgrade, rollback, template, lint, plugin, ... applications/deployments etc. For example, Rimantas shows us the proper way to change values of a helm chart (p.97). "To change values, it is recommended to use the override-values.yaml file ...Changing the default values.yaml file that comes with the chart is not recommended, as you might lose track of changes in the newer versions of the file.”! (It is a very good tip !)Ch.10 has some kubectl best practices and docker commands. I like the side by side equivalent of docker commands in kubectl. When the k8s API server is not responding, then these docker commands can help you troubleshoot more.Cons: there are a few syntax errors on p. 46, 53 and 70 when it should be double dashes " - -" but shown as single long dash "-" in the code block. Likely a formatting issue when published.

As other reviews have mentioned, this book does a great job of using kubectl to create and modify Kubernetes cluster resources. The official documentation can be overwhelming when new to Kubernetes. This book does a good job of aiding with order and structure to learn kubectl.This book also touches on kustomize and Helm, a nice surprise and not something often discussed while teaching kubectl.I would have enjoyed more detail on creating kubectl plugins. A more thorough chapter on creating plugins would make this book really stand out.

Can I download the code files for Early Access titles? Chevron down icon Chevron up icon

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? Chevron down icon Chevron up icon

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.

We'll let you know every time there has been an update to a course that you've bought in 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.
