Model and Operate Datacenter by Kubernetes at eBay
summary
eBay models its physical datacenter and fleet as Kubernetes CRDs and runs controllers to operate them at scale, controlling tens of thousands of machines and ~200,000 VMs. Concrete models include CRD model for Rack, L2Domain, NetworkScope, Asset, Flavor, K8sCluster and a SaltStack-based configuration layer that does OS install and disk partitioning. Controllers provision nodes, bootstrap clusters, and perform rack-level rolling upgrades for Kubernetes components; result: search, Hadoop, databases and edge POPs run on Kubernetes in production.
