Education will be critical. As the early adopters of Kubernetes make way to the majority, it is very important to have the right resources for organizations and developers to pick up Kubernetes and be productive quickly. There are already some pretty good resources, and, in the future, I predict that the number and quality will just increase. Of course, the book you're reading right now is part of this drive.
The official Kubernetes documentation is getting better and better. The online tutorials are great for getting started:
- The CNCF has a free introductory Kubernetes course (as well as more advanced paid courses), at https://www.cncf.io/certification/training/.
- Google has created a few Udacity courses on Kubernetes. Check them out at https://www.udacity.com/course/scalable-microservices-with-kubernetes--ud615.
- Another excellent resource is KataCoda, which provides a completely free Kubernetes playground, where you can get a private cluster within seconds, in addition to multiple hands-on tutorials on advanced topics, at https://www.katacoda.com/courses/kubernetes.
There are also a lot of paid training options for Kubernetes. As the popularity of Kubernetes grows even further, more and more options will be available.
