Kubernetes (,k(j)uːbərˈnɛtɪs,-ˈneɪtɪs,-ˈneɪtiːz,_-ˈnɛtiːz, commonly abbreviated K8s) is an open-source container orchestration system for automating software deployment, scaling, and management. Originally designed by Google, the project is now maintained by the Cloud Native Computing Foundation.
The name Kubernetes originates from Ancient Greek, meaning 'helmsman' or 'pilot'. Kubernetes is often abbreviated as K8s, counting the eight letters between the K and the s (a numeronym).
Kubernetes works with various container runtimes, such as containerd and CRI-O. Its suitability for running and managing large cloud-native workloads has led to widespread adoption of it in the data center. There are multiple distributions of this platform – from independent software vendors (ISVs) as well as hosted-on-cloud offerings from all the major public cloud vendors.
Kubernetes (κυβερνήτης, or , 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.
Google was already offering managed Kubernetes services, while Red Hat was supporting Kubernetes as part of OpenShift since the inception of the Kubernetes project in 2014. In 2017, the principal competitors rallied around Kubernetes and announced adding native support for it:
