Kubernetes is an open-source container orchestration system for automating software deployment, scaling, and management.
Google originally designed Kubernetes, but the Cloud Native Computing Foundation now maintains the project.
Kubernetes works with Docker, Containerd, and CRI-O.[7] Originally, it interfaced exclusively with the Docker runtime[8] through a "Dockershim"; however, from 2016[citation needed] up to April 2022, Kubernetes has deprecated the shim in favor of directly interfacing with the container through Containerd, or replacing Docker with a runtime that is compliant with the Container Runtime Interface . With the upcoming release of v1.24 in April 2022, "Dockershim" has been removed entirely.
Amazon, Google, IBM, Microsoft, Oracle, Red Hat, SUSE and VMware offer Kubernetes-based platforms or infrastructure as a service (IaaS) that deploy Kubernetes.
Kubernetes was first announced by Google in mid-2014. Joe Beda, Brendan Burns, and Craig McLuckie were the initial founders of Kubernetes,but other Google engineers, including Brian Grant and Tim Hockin, joined them shortly thereafter. Google's Borg system had a significant influence on the design and development of Kubernetes. Many of the top contributors to the project previously worked on Borg. The original codename for Kubernetes within Google was Project 7, a reference to the Star Trek ex-Borg character Seven of Nine. The seven spokes on the wheel of the Kubernetes logo are a reference to that codename. The original Borg project was entirely in C++,but Kubernetes source code is in the Go language.
Kubernetes 1.0 was released on July 21, 2015,along which Google partnered with the Linux Foundation to form the Cloud Native Computing Foundation (CNCF)and offered Kubernetes as a seed technology. In February 2016,the Helmpackage manager for Kubernetes was released. On March 6, 2018, Kubernetes Project reached the ninth place in the list of GitHub projects by the number of commits, and second place in authors and issues, after the Linux kernel.
Until version 1.18, Kubernetes followed an N-2 support policy, meaning that the three most recent minor versions receive security updates and bug fixes.Starting with version 1.19, Kubernetes follows an N-3 support policy.
