Jenkins on Kubernetes

This folder contains a Jenkins StatefulSet and Service.

• statefulset.yaml provisions persistent Jenkins data with a volumeClaimTemplates request.
• service.yaml exposes both Jenkins UI and agent ports.
• Review resources, storage size, and service type before production use.
