Context: Kubernetes (κυβερνήτης kubernḗtēs, Greek for "steersman, navigator" or "guide", and the etymological root of cybernetics) was announced by Google in mid-2014. The project was created by Joe Beda, Brendan Burns, and Craig McLuckie, who were soon joined by other Google engineers, including Brian Grant and Tim Hockin.

The design and development of Kubernetes was influenced by Google's Borg cluster manager. Many of its top contributors had previously worked on Borg; they codenamed Kubernetes "Project 7" after the Star Trek ex-Borg character Seven of Nine and gave its logo a seven-spoked wheel. Unlike Borg, which was written in C++, Kubernetes source code is in the Go language.

Kubernetes 1.0 was released on July 21, 2015. Google worked with the Linux Foundation to form the Cloud Native Computing Foundation (CNCF) and offered Kubernetes as a seed technology. In February 2016, the Helm package manager for Kubernetes was released.
