Kubernetes v1.21.3 releases, container cluster management system
Kubernetes is an open-source system for managing containerized applications across multiple hosts; providing basic mechanisms for deployment, maintenance, and scaling of applications.
Kubernetes builds upon a decade and a half of experience at Google running production workloads at scale using a system called Borg, combined with best-of-breed ideas and practices from the community.
Kubernetes is hosted by the Cloud Native Computing Foundation (CNCF). If you are a company that wants to help shape the evolution of technologies that are container-packaged, dynamically scheduled, and micro-services-oriented, consider joining the CNCF. For details about who’s involved and how Kubernetes plays a role, read the CNCF announcement.
