Extending Deployment for Internet Financial Mission-Critical Scenarios
summary
Ant Financial extends Kubernetes Deployment with a custom cafe deployment controller that implements in-place upgrade and a confirmable, risk‑controlled rollout: create 100 replicas as staged batches (beta: one pod per DC, then 4‑4‑2 groups), require human confirmation per batch, support abort/rollback, and reschedule when an in‑place slot lacks resources. It preserves fixed IPs for VM‑style tooling, supports active/active multi‑DC topology and multi-active replication, uses readiness gates and load‑balancer finalizers to ensure graceful traffic drain.
