Building a Kubernetes on Bare-Metal Cluster
summary
Builds Kubernetes clusters on bare metal to run Wikipedia traffic on 1,200 hardware machines, packaging Debian kube 1.7 and etcd, using calico with BGP to announce routable pod IPs (10.0.0.0/8) and IPv6 support, and routing external traffic via nodePort plus an in‑house PIBO load balancer that programs lvs direct routing. Uses one-namespace-per-service, Helm with per-namespace Tiller, active‑active across two DCs and simple canary releases; deployment is live and serving production traffic.
