如何为我的kubernetes部署和服务创建ingress nginx

Question

我可以使用LoadBalancer服务类型访问我的django应用程序部署，但我试图切换到ClusterIP服务类型和ingress nginx，但当我试图通过主机url访问网站时，我得到了503服务暂时不可用。对入口的描述还示出了CCD_ 1和CCD_。我做错了什么？

这是我的服务和入口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
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:

- host: django.example.com
http:
paths:
- path: /
pathType: Prefix

service:

ingressClassName: nginx

我想您忘记了在服务中建立与部署的链接。

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

您的标签也必须在部署中设置：

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