如何为我的kubernetes部署和服务创建ingress nginx?

我可以使用LoadBalancer服务类型访问django应用程序部署,但我正在尝试切换到ClusterIP服务类型和ingress nginx,但当我尝试通过主机url访问网站时,503服务暂时不可用。描述入口也表明 error: endpoints "django-service" not found 和 error: endpoints "default-http-backend" not found .我做错了什么?

这是我的服务和ingress yaml:

---
apiVersion: v1
kind: Service
metadata:
  name: django-service
spec:
  type: ClusterIP
  ports:
  - name: http
    protocol: TCP
    port: 80
    targetPort: 8000
---
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: django-ingress
  annotations:
    nginx.ingress.kubernetes.io/rewrite-target: /
    nginx.ingress.kubernetes.io/force-ssl-redirect: 'true'
    nginx.ingress.kubernetes.io/ssl-redirect: 'true'
spec:
  tls:
  - hosts:
    - django.example.com
  rules:
  - host: django.example.com
    http:
      paths:
      - path: /
        pathType: Prefix
        backend:
          service:
            name: django-service
            port:
              number: 80
  ingressClassName: nginx

kubectl获得全部
