Run Training as a Kubernetes Job

Execute batch training to completion on the cluster.

Training Is Not a Server

A model server runs forever, but a training run should start, finish, and stop. Kubernetes has a different object built for that: the Job. 🏁

A Job creates one or more Pods and watches them until they exit successfully. Once training succeeds, the Job is done and frees its resources.
