Questions tagged [google-kubernetes-engine]
Google Kubernetes Engine is a cluster manager and orchestrator for running Docker containers. It schedules your containers into the cluster and manages them automatically based on requirements you define (such as CPU and memory). It's built on the open source Kubernetes system, giving you the flexibility to take advantage of on-premises, hybrid, or public cloud infrastructure. It was formerly called Google Container Engine.
