Keynote: Pushing the Limits of Kubernetes with Game of Thrones

on YouTube ↗21m

" summary

HBO moves 15,000 pods into production to survive Game of Thrones Season 7 premiere, provisioning clusters on AWS with Terraform modules, autoscaler tweaks and per-node ELBs for production. Modules add reserve minions and backup minions (tainted and affinity-bound) so Prometheus on EBS keeps data during scale downs. Networking uses flannel and surfaces UDP drops and DNS timeouts fixed by kube-dns tuning (cache 10,000, --local answers), plus weekly mega load tests and metric filtering for ~20k containers.
