集群验证测试
所有组件部署完成后，通过创建 Nginx 应用验证集群是否正常工作。
创建应用
# nginx-test.yaml
apiVersion: apps/v1
kind: Deployment
metadata:
name: nginx-deployment
spec:
replicas: 3
selector:
matchLabels:
app: nginx
template:
metadata:
labels:
app: nginx
spec:
containers:
- name: nginx
image: nginx:latest
ports:
- containerPort: 80
---
apiVersion: v1
kind: Service
metadata:
name: nginx-service
spec:
type: NodePort
selector:
app: nginx
ports:
- port: 80
targetPort: 80
nodePort: 30080
yaml
部署和验证
kubectl apply -f nginx-test.yaml
kubectl get pods -o wide
kubectl get svc
curl http://<node-ip>:30080
bash
验证要点
- Pod 是否能正常调度到 Worker 节点
- Pod 之间是否能互相通信
- Service DNS 解析是否正常
- NodePort 是否能从外部访问
