kubernetes Minikube:无法从外部访问节点端口服务 [英] kubernetes Minikube : Node port service not accessible from outside

问题描述

我正在尝试在 minikube (Windows-10) 上部署简单的 Spring Boot REST 服务.下面是我的配置

Docker 文件

FROM openjdk:8-jdk-alpine入口点 ["/usr/bin/java", "-jar", "/usr/share/myservice/minikube-spring-boot-demo-0.0.1-SNAPSHOT.jar"]添加目标/minikube-spring-boot-demo-0.0.1-SNAPSHOT.jar/usr/share/myservice/libARG JAR_FILE添加目标/${JAR_FILE}/usr/share/myservice/minikube-spring-boot-demo-0.0.1-SNAPSHOT.jar曝光 8080

docker 镜像运行良好，我可以运行该应用程序.

docker run -p 8080:8080 minikube-spring-boot-demo:0.0.1-SNAPSHO

服务详情

我无法使用 service-ip:Nodeport/Uri
访问其余端点

解决方案

minikube 正在虚拟机中运行.机器外的localhost或127.0.0.1都无法访问服务.

尝试运行 minikube service minikube-spring-boot-demo-service.它将显示服务详细信息并在浏览器中打开服务.

I am trying to deploy simple spring boot REST service on minikube (Windows-10). Below are my configuration

Docker file

FROM openjdk:8-jdk-alpine
ENTRYPOINT ["/usr/bin/java", "-jar", "/usr/share/myservice/minikube-spring-boot-demo-0.0.1-SNAPSHOT.jar"]
ADD target/minikube-spring-boot-demo-0.0.1-SNAPSHOT.jar  /usr/share/myservice/lib
ARG JAR_FILE
ADD target/${JAR_FILE} /usr/share/myservice/minikube-spring-boot-demo-0.0.1-SNAPSHOT.jar
EXPOSE 8080

docker image is running fine and i am able to run the app.

docker run -p 8080:8080 minikube-spring-boot-demo:0.0.1-SNAPSHO

kubectl get all status

kubectl cluster-info

minikube logs

Service Details

i am not able to access the rest endpoint using service-ip:Nodeport/Uri
http://127.0.0.1:30008/hello

http://172.17.0.2:30008/hello

Anything i am missing here? any inputs will be useful.

output of netstat -a

解决方案

minikube is running in a virtual machine. Services can't be accessed through either localhost or 127.0.0.1 out of the machine.

Try to run minikube service minikube-spring-boot-demo-service. It will show service details and open the service in the browser.
