Extending Deployment for Internet Financial Mission-Critical Scenarios
summary
Ant Financial builds a custom CRD called cafe deployment CRD that adds in-place upgrades, stable pod IPs and active‑active multi‑datacenter topology to Kubernetes. It deploys in a gated sequence—beta then 4‑4‑2 batching—requiring human confirmation per batch, supports rescheduling when an in‑place node lacks capacity, and integrates with ReplicaSet/StatefulSet. Graceful shutdown uses readinessGate plus a load‑balancer finalizer to drain traffic. Demo shows abort and automatic rollback work and batches progress only after confirmation.
