Kubernetes
/ˌkuːbərˈnɛtɪs/
n. “You don’t run containers. You herd them.”
Kubernetes is a container orchestration system designed to manage, scale, and keep alive large numbers of containerized applications. If Docker made containers practical, Kubernetes made them survivable in the real world — where machines fail, traffic spikes, deployments go wrong, and nobody wants to SSH into production at 3 a.m.
