During the early days of Kubernetes, there “were no ebooks available” on the subject, Hightower said. The main goal was to help “raise the profile of the people with the job of trying to manage applications.”

“I think the whole point was when I was showing Kubernetes off [as] a contributor [and] building things around the ecosystem, my product work at CoreOS — we were all trying to solve problems that we all had in the past,” Hightower said. “We were trying to uplift the community. We were pretty sure that technology was going to be okay over time.”

More specific to Kubernetes as a platform, the concern was whether the DevOps community could grasp the concept of how distributed systems functioned in order to use them. Many in the community were familiar with configuration management tools Puppet, Chef and Ansible, for example, and “were getting exposure to things like Docker, in terms of packaging their applications and shipping them to servers in a slightly different way,” Hightower said.

“But not a lot of people really understood this whole distributed systems thing. And I think over the last five years, we’ve had so many people — either through the Kubernetes certification or ebooks — where there’s now enough education and an information ecosystem that’s based on experience and analysis, that we’re now getting people to understand what this stuff is all about.”

Hightower’s “jumping into Kubernetes” began when he was working at CoreOS and heard Kubernetes was about to be announced. On the eve of the launch, Hightower began to learn everything he could about the platform “in one night” after accessing the repository for a blog post.
