This is the second book you should buy after 'Kubernetes Up & Running'. 'Cloud Native DevOps' introduces the new world of cloud native applications and gives you a wealth of practical tips on how to run Kubernetes clusters, how to write and deploy Kubernetes applications, and how to apply DevOps best practices: infrastructure as code, continuous deployment, metrics, observability. We also cover managing cloud infrastructure with Terraform, migrating legacy applications to Kubernetes, building cloud native microservices in Go, and we provide complete, working example code for everything in the book, available in a separate GitHub repo. This book takes you from zero to Kubernetes in 210 densely-packed pages!
If you’re a cloud native novice, you’ll learn everything you need to know to get your application into the cloud. If you’ve been working with Kubernetes for a while, you’ll learn about the latest tools and features, community best practices, and battle-tested recipes from real production clusters. Even if you’re an experienced Kubernetes user, there’ll be a few things in this book that you didn’t know… we hope!
Kubernetes is hard
If you’ve been hearing a lot about Kubernetes, and maybe read some things about it, or even tried to get started running something in Kubernetes, you may be feeling a little dispirited, confused, overwhelmed, puzzled, and possibly suffering the early symptoms of imposter syndrome. Well, don’t worry: it’s not just you.
Here’s the shocking truth that conference talks, promotional material, corporate press releases, and those other blogs won’t tell you:
Kubernetes is hard.
Of course, everyone who’s enthusiastic about Kubernetes wants to tell you how easy it is. “You can learn Kubernetes in a day!” Well, that would be quite a day. While Kubernetes is powerful and useful, it’s not necessarily so easy to get your head around, especially at first. It involves a lot of puzzling jargon and technical terms which don’t mean much to the newbie:
- Pod
- StatefulSet
- PersistentVolumeClaim
- Custom Resource Definition
- Ingress
- Deployment
- Horizontal Pod Autoscaler
… and so on. If you feel depressed and angry at the amount of new things Kubernetes requires you to learn, then we can absolutely relate to that. We’ve been through some of the same emotions on our Kubernetes journey, which is by no means complete, but the point of this blog is to hammer a few signposts into the swamp to help others feeling similarly lost.
