Question

使用NodePort服务时，可以进入我的应用程序。但是，当我尝试通过Ingress进行访问时，我总是会收到HTTP 404。对于我有回应的这张图片中的测试图片gcr.io/google-samples/hello-app:1.0，这不会发生。这是我的部署：

apiVersion: apps/v1
kind: Deployment
metadata:
 name: app-backend-deployment
 labels:
  app: app-backend
spec:
 replicas: 1
 selector:
    matchLabels:
      app: app-backend
 template:
    metadata:
      labels:
        app: app-backend
    spec:
     containers:
     - name: app-backend
       image: go-app-backend
       ports:
       - containerPort: 8100
       imagePullPolicy: Never

我的NodePort服务：

apiVersion: v1
kind: Service
metadata:
 labels:
  app: app-backend-deployment
 name: app-backend-svc-nodeport
spec:
 type: NodePort
 ports:
 - port: 8020
   protocol: TCP
   targetPort: 8100
 selector:
  app: app-backend

从那时起，当我致电$ minikube service church-backend-svc-nodeport --url时，我会得到我的应用运行所在的地址。

但是当我尝试配置我的应用以在Ingress上获取路由时，它不起作用：

apiVersion: networking.k8s.io/v1beta1
kind: Ingress
metadata:
 annotations:
  nginx.ingress.kubernetes.io/rewrite-target: /$1
 name: app-backend-ingress
spec:
 rules:
 - host: app-backend.io
   http:
     paths:
       - backend:
          serviceName: app-backend-svc-nodeport
          servicePort: 8020
         path: /backend

但是，当我使用示例问候词应用程序（https://kubernetes.io/docs/tasks/access-application-cluster/ingress-minikube/）进行配置并替换ingress.yml中的所有内容时，一切正常。谁能看看这个，告诉我我做错了什么？

如果我没记错的话，您需要将ingress放入后端path: /backend(/|$)(.*)和元数据nginx.ingress.kubernetes.io/rewrite-target: /$2

apiVersion: networking.k8s.io/v1beta1
kind: Ingress
metadata:
  annotations:
    nginx.ingress.kubernetes.io/rewrite-target: /$2
  name: app-backend-ingress
spec:
  rules:
  - host: app-backend.io
    http:
      paths:
      - backend:
        serviceName: app-backend-svc-nodeport
        servicePort: 8020
        path: /backend(/|$)(.*)
