部署顺序：

1. 先创建 PV

kubectl apply -f elasticsearch-pv.yaml

2. 再创建 PVC（会自动绑定到 PV）

kubectl apply -f elasticsearch-pvc.yaml

3. 创建 StatefulSet 和 Service

kubectl apply -f elasticsearch-statefulset.yaml
kubectl apply -f elasticsearch-service.yaml

验证部署：

检查 PV 和 PVC 状态

kubectl get pv
kubectl get pvc

检查 Pod 状态

kubectl get pods -l app=elasticsearch

检查 Service

kubectl get svc elasticsearch
