Kubernetes at Reddit: Tales from Production
Talkat KubeCon + CloudNativeCon North America 2019 · on Thursday, 2019-11-21· at 15:20· Ballroom Sec 20AB - San Diego Convention Center, Upper Level·
summary
Reddit describes rapid org-wide Kubernetes adoption after a March 2019 InfraRed launch with a two-week onboarding cadence, now running about 45 services in production and ~20 queued, spread across roughly 19 clusters. Deploys use Spinnaker + Helm initially, moving Reddit-authored services to a Starlark resource generator; OPA enforces cluster policies but caused API timeouts on pre-1.14 control planes before admission timeout fixes. Local dev pivots from minikube/scaffold to remote-first + Tilt, and single‑AZ cluster groups reduce blast radius and outages.
