无法使用 Minikube 在 Windows Home 上的浏览器中访问 Kubernetes Ingress? [英] Could not access Kubernetes Ingress in Browser on Windows Home with Minikube?
问题描述
我面临的问题是我无法使用其 IP 访问浏览器上的 Kubernetes Ingress.我已经在 Windows 10 Home 上安装了 K8s 和 Minikube.
我正在关注这个官方文档 -
接下来，我公开了我在上面创建的部署.为此，我运行了以下命令.
kubectl 公开部署 web --type=NodePort --port=8080
这创建了一个可以通过运行以下命令看到的服务:
kubectl 获取服务网站服务截图如下:
我现在可以通过运行以下命令在浏览器上访问该服务:
minikube 服务网站
在下面的屏幕截图中，您可以看到我可以在浏览器上查看它.
接下来，我通过运行以下命令创建了一个 Ingress:
kubectl apply -f
入口 ip 列为
192.168.49.2.所以这意味着如果我应该在浏览器中打开它，那么它应该会打开，但不幸的是没有.显示网站无法访问.请参阅下面的截图.有什么问题.请给我一个解决方案?
我还在 etchosts 文件中添加了映射.
192.168.49.2 hello-world.info然后我也尝试在浏览器上打开 hello-world.info 但没有成功.
在下图中，我对
hello-world.info执行 ping 操作，IP 地址为 192.168.49.2.这表明 etchosts 映射是正确的:我也 curl 到 minikube ip 和
hello-world.info并且都超时.见下图:kubectl describe services web提供了以下详细信息:名称:web命名空间:默认标签:应用程序=网络注释:<none>选择器:app=web类型:节点端口IP:10.100.184.92端口:<unset>8080/TCP目标端口:8080/TCP节点端口:<unset>31880/TCP端点:172.17.0.4:8080会话亲和力:无外部流量策略:集群事件:<无>kubectl describe ingress example-ingress给出以下输出:名称:example-ingress命名空间:默认地址:192.168.49.2默认后端:default-http-backend:80(<错误:未找到端点default-http-backend">)规则:主机路径后端---- ---- --------hello-world.info/web:8080 172.17.0.4:8080)注解:nginx.ingress.kubernetes.io/rewrite-target:/$1事件:<无>请帮忙.谢谢.
解决方案和 OP 有同样的问题，只能在
minikube ssh中工作，分享下面的 ingress.yaml.apiVersion:networking.k8s.io/v1种类:入口元数据:名称:前端入口注释:nginx.ingress.kubernetes.io/rewrite-target:/$2规格:默认后端:服务:名称:default-http-backend港口:数量:80规则:- 主机:myapp-com # 域(即需要更改主机表)网址:path: # 下面指定路径，只有在超过1条路径时才有效；如果只有 1 条路径，则始终使用/作为路径- 小路:/路径类型:前缀后端:服务:名称:frontend-service # 内部服务港口:number: 8080 # 内部服务暴露的端口号- 路径:/e($|/)(.*)路径类型:前缀后端:服务:name: express-service # 内部服务港口:number: 3000 # 内部服务暴露的端口号I am facing the problem which is that I could not access the Kubernetes Ingress on the Browser using it's IP. I have installed K8s and Minikube on Windows 10 Home.
I am following this official document - https://kubernetes.io/docs/tasks/access-application-cluster/ingress-minikube/
First I created the deployment by running this below command on Minikube.
kubectl create deployment web --image=gcr.io/google-samples/hello-app:1.0
The deployment get created which can be seen on the below image:
Next, I exposed the deployment that I created above. For this I ran the below command.
kubectl expose deployment web --type=NodePort --port=8080
This created a service which can be seen by running the below command:
kubectl get service webThe screenshot of the service is shown below:
I can now able to visit the service on the browser by running the below command:
minikube service web
In the below screenshot you can see I am able to view it on the browser.
Next, I created an Ingress by running the below command:
kubectl apply -f https://k8s.io/examples/service/networking/example-ingress.yaml
By the way the ingress yaml code is:
apiVersion: networking.k8s.io/v1 kind: Ingress metadata: name: example-ingress annotations: nginx.ingress.kubernetes.io/rewrite-target: /$1 spec: rules: - host: hello-world.info http: paths: - path: / pathType: Prefix backend: service: name: web port: number: 8080The ingress gets created and I can verify it by running the below command:
kubectl get ingressThe screenshot for this is given below:
The ingress ip is listed as
192.168.49.2. So that means if I should open it in the browser then it should open, but unfortunately not. It is showing site can't be reached. See the below screeshot.What is the problem. Please provide me a solution for it?
I also added the mappings on etchosts file.
192.168.49.2 hello-world.infoThen I also tried opening hello-world.info on the browser but no luck.
In the below picture I have done ping to
hello-world.infowhich is going to IP address 192.168.49.2. This shows etchosts mapping is correct:I also did curl to minikube ip and to
hello-world.infoand both get timeout. See below image:The
kubectl describe services webprovides the following details:Name: web Namespace: default Labels: app=web Annotations: <none> Selector: app=web Type: NodePort IP: 10.100.184.92 Port: <unset> 8080/TCP TargetPort: 8080/TCP NodePort: <unset> 31880/TCP Endpoints: 172.17.0.4:8080 Session Affinity: None External Traffic Policy: Cluster Events: <none>The

Thank you.
解决方案Having same issue as OP and things only work in
minikube ssh, sharing the ingress.yaml below.apiVersion: networking.k8s.io/v1 kind: Ingress metadata: name: frontend-ingress annotations: nginx.ingress.kubernetes.io/rewrite-target: /$2 spec: defaultBackend: service: name: default-http-backend port: number: 80 rules: - host: myapp-com # domain (i.e. need to change host table) http: paths: # specified path below, only be working when there is more than 1 path; If only having 1 path, it's always using / as path - path: / pathType: Prefix backend: service: name: frontend-service # internal service port: number: 8080 # port number that internal service exposes - path: /e($|/)(.*) pathType: Prefix backend: service: name: express-service # internal service port: number: 3000 # port number that internal service exposes这篇关于无法使用 Minikube 在 Windows Home 上的浏览器中访问 Kubernetes Ingress?的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
