When I finished the last book (The DevOps 2.5 Toolkit: Monitoring, Logging, and Auto-Scaling Kubernetes), I wanted to take a break from writing for a month or two. I thought that would clear my mind and help me decide which subject to tackle next. Those days were horrible. I could not make up my mind. So many cool and useful tech is emerging and being adopted. I was never as undecided as those weeks. Which should be my next step?
I could explore serverless. That’s definitely useful, and it might be considered the next big thing. Or I could dive into Istio. It is probably the biggest and the most important project sitting on top of Kubernetes. Or I could tackle some smaller subjects. Kaniko is the missing link in continuous delivery. Building containers might be the only thing we still do on the host level, and Kaniko allows us to move that process inside containers. How about security scanning? It is one of the things that are mandatory in most organizations, and yet I did not include it in “The DevOps 2.4 Toolkit: Continuous Deployment To Kubernetes”. Then there is skaffold, prow, KNative, and quite a few other tools that are becoming stable and very useful. Continue reading →
Soon after I started working on The DevOps 2.3 Toolkit: Kubernetes, I realized that a single book could only scratch the surface. Kubernetes is vast, and no single book can envelop even all the core components. If we add community projects, the scope becomes even more extensive. Then we need to include hosting vendors and different ways to set up and manage Kubernetes. That would inevitably lead us to third-party solutions like OpenShift, Rancher, and DockerEE, to name a few. It doesn’t end there. We’d need to explore other types of community and third-party additions like those related to networking and storage. And don’t forget the processes like, for example, continuous delivery and deployment. All those things could not be explored in a single book so The DevOps 2.3 Toolkit: Kubernetes ended up being an introduction to Kubernetes. It can serve as the base for exploring everything else.
The moment I published the last chapter of The DevOps 2.3 Toolkit: Kubernetes, I started working on the next material. A lot of ideas and tryouts came out of it. It took me a while until the subject and the form of the forthcoming book materialized. After a lot of consultation with the readers of the previous book, the decision was made to explore continuous delivery and deployment processes in a Kubernetes cluster. The high-level scope of the book you are reading right now was born. Continue reading →
The goal of this book is not to convince you to adopt Kubernetes but to provide a detailed overview of its features. I want you to become confident in your Kubernetes knowledge and only then choose whether to embrace it. That is, unless you already made up your mind and stumbled upon this book in search of Kubernetes guidance. Continue reading →
The third installment in The DevOps Toolkit Series is public! Even though, while I’m writing this post, only 20% of The DevOps 2.2 Toolkit: Self-Healing Clusters is finished, I hope you’ll pick it up and send me your feedback. I need your help in setting the direction of the book. I need you to help me shape it into something great. I need you to help me make this book a community effort.
DevOps is the word of the year. Everyone speaks about it, and many are hoping to apply it, even though most are confused what it truly means.
Inquiring about DevOps does not seem to help. If you speak with a software vendor, he’ll tell you that all you need to become DevOps ninja is to purchase his product. Puppet, Chef, Ansible, Docker, Terraform, Packer, Jenkins, Nexus, Git… Every software vendor seems to have a DevOps sticker attached to his product. You’ll notice those stickers being right next to “we make Docker easy” and “we convert your architecture into microservices.” Continue reading →
I published The DevOps 2.1 Toolkit: Docker Swarm on LeanPub early. I think that only around 20% was written when it went public. That allowed you to get early access to the material, and me to get your feedback. The result is fantastic. Many send me their notes, reported bugs, proposed suggestions for improvements, recommended tools and processes that should be explored, and so on. Continue reading →
At the beginning of 2016, I published The DevOps 2.0 Toolkit. It took me a long time to finish it. Much longer than I imagined.
I started by writing blog posts in TechnologyConversations.com. They become popular and I received a lot of feedback. Through them, I clarified the idea behind the book. The goal was to provide a guide for those who want to implement DevOps practices and tools. At the same time, I did not want to write a material usable to any situation. I wanted to concentrate only on people that truly want to implement the latest and greatest practices. I hoped to make it go beyond the “traditional” DevOps. I wished to show that the DevOps movement matured and evolved over the years and that we needed a new name. A reset from the way DevOps is implemented in some organizations. Hence the name, The DevOps 2.0 Toolkit. Continue reading →
