# Kubernetes Production Readiness Review a workload against the failures that actually take services down: node loss, rollouts, restarts, and saturation. ## Purpose **Use this when:** - Reviewing a Deployment, StatefulSet or Helm chart before it takes production traffic. - A service exists in production and nobody has ever checked it against a baseline. - A post-incident action item is "make this service more reliable" and you need a concrete list. **Do not use this when:** - The workload is currently broken — fix it first with `kubernetes-troubleshooting`. Readiness review is for healthy services. - The question is about cluster or platform readiness (control plane HA, upgrade strategy, backup of etcd) rather than about a workload. That is a different review. **What this skill assumes:** access to the manifests (Git, Helm values, or the live objects), and a stated environment. A review of `kubectl get -o yaml` output misses defaults applied by admission controllers, so prefer reviewing both the source manifest and the live object. ## Operating Procedure 1. **Get the real manifest.** Render Helm (`helm template`) or fetch the live object. Review what is deployed, not what someone believes is deployed. 2. **Classify the workload.** Stateless request-serving, stateful, batch, and singleton workloads have different correct answers. Applying stateless advice to a StatefulSet causes data loss. 3. **Walk the checklist** below in order. Record each item as pass, f
