Initially developed by a group of Google engineers, the first Kubernetes commit on GitHub was made on June 6, 2014, paving the way for the release of Kubernetes v1.0 on July 10, 2015.
Today, Kubernetes is the leading container-orchestration system, with countless companies building on and migrating to this popular open-source technology. A Container Journal survey found that 95% of Kubernetes users find clear benefits from using it, with resource utilization and shorter software development leading the way.
