Building and Managing Kubernetes with Kubernetes
summary
eBay runs a fleet-management layer that models racks, switches, subnets, OS images and hosts as CRDs for hardware and OS and drives provisioning with controllers that allocate assets, IPs and kickstart bare metal. Clusters are built with Salt where each Salt deployment is tied to a Git commit ID; controllers perform staged rolling upgrades via bucketed transactions and a health-monitor framework. Production scale: 50+ clusters, ~30,000 hosts, ~160,000 pods and ~15 edge clusters, and VMs run via virtlet as Pods.
