Run your Kubernetes cluster on OpenStack in Production
summary
Shows how Kubernetes on OpenStack uses Kuryr/CNI, OVN, Neutron and Octavia to get bare‑metal datapath: SR-IOV and OVS‑DPDK are exposed to pods, provider networks in OpenShift 4.6 remove floating IPs, and Kuryr avoids double VXLAN encapsulation. OVN+Octavia (node L4) outperforms Amphora VMs for throughput, OVN incremental ACL processing cuts CPU and latency by over 50%, and a DPDK demo hits 4 million pps with one core, demonstrating production-grade telco performance.
