如何為我的kubernetes部署和服務創建ingress-nginx？

我可以使用 LoadBalancer 服務型別訪問我的 django 應用程式部署，但我正在嘗試切換到 ClusterIP 服務型別和 ingress-nginx，但是當我嘗試通過主機 url 訪問該站點時，我得到 503 Service Temporarily Unavailable。描述入口還顯示error: endpoints "django-service" not found和 error: endpoints "default-http-backend" not found。我究竟做錯了什么？

這是我的服務和入口 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

  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

我認為您忘記在您的服務中與您的部署建立鏈接。

apiVersion: v1
kind: Service
metadata:
  name: django-service
spec:
  type: ClusterIP
  ports:
  - name: http
    protocol: TCP
    port: 80
    targetPort: 8000
  selector:
    app: your-deployment-name

您的標簽也必須在您的部署中設定：

spec:
  selector:
    matchLabels:
      app: your-deployment-name
  template:
    metadata:
      labels:
        app: your-deployment-name
