Kubernetes入口-无法访问

Question

我是Kubernetes中Ingress的新手。我在AKS集群中安装了Ingress NGINX控制器。我的应用程序在testns(命名空间(中的pod(端口80(中运行。我在同一个命名空间中为它创建了一个服务。现在我想从外部访问我的应用程序。所以我为它创建了一个Ingress yaml。

服务.yaml

kubectl get svc -A | grep my-svc
testns    my-svc                         ClusterIP      10.0.116.192   <none>          80/TCP                             93m

进入

Name:             example-ingress
Namespace:        testns
Address:
Default backend:  default-http-backend:80 (<error: endpoints "default-http-backend" not found>)
Rules:
Host        Path  Backends
----        ----  --------
*
/apple   my-svc:80 (10.244.1.33:80)
Annotations:  ingress.kubernetes.io/rewrite-target: /
Events:       <none>

入口.yaml

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
name: example-ingress
annotations:
ingress.kubernetes.io/rewrite-target: /
spec:
rules:
- http:
paths:
- path: /apple
backend:
serviceName: my-svc
servicePort: 80

当我使用<IP_ADDRESS_OF_THE_INGRESS>apple，则会给出404错误。我想知道为什么应用程序无法访问。

尝试将入口类添加到YAML配置kubernetes.io/ingress.class: "nginx"中

作为注释

kubernetes.io/ingress.class: "nginx"
nginx.ingress.kubernetes.io/rewrite-target: /

示例

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
name: example-ingress
annotations:
kubernetes.io/ingress.class: "nginx"
nginx.ingress.kubernetes.io/rewrite-target: /
spec:
rules:
- http:
paths:
- path: /apple
backend:
serviceName: my-svc
servicePort: 80
