Chef On The Train
summary
DB Systel runs a Chef-based fleet management system for 255 train sets, using Scientific Linux, KVM guests and AWS-hosted Chef servers to give each platform four chef clients per platform that can boot from image or run in chef local mode for offline installs. A gateway enforces non-intrusiveness so over‑the‑air updates, pinned cookbook environments and Jenkins/Packer/Cobbler builds push changes fast while reserving hard drive releases for risky network or config shifts, and the system works in production.
