get: bad option;当尝试在K8容器中挂载azure文件共享时，对于几个文件系统(例如nfs, cifs).

Question

我创建了一个Azure文件共享，我可以在我的windows 10笔记本电脑上使用地图网络驱动器连接到它。我创建了一个hello-world spring引导应用程序，它带有用于azure文件共享的卷挂载配置，并试图在docker-desktop中部署到Kubernetes中。但是我的pod不启动-

hello-world-9d7479c4d-26mv2   0/1     ContainerCreating   0          15s

当我描述POD -

时，我可以在事件中看到错误

Events:

然后我更新了我的Dockerfile来安装cifs-utils -

FROM ubuntu:16.04
# Install Java
RUN apt-get update && 
apt-get install -y openjdk-8-jdk && 
apt-get install -y ant && 
apt-get install -y cifs-utils && 
apt-get clean;
ENV PORT 8080
EXPOSE 8080
COPY target/*.jar /opt/app.jar
WORKDIR /opt
CMD ["java", "-jar", "app.jar"]

这个错误仍然没有消失。我在谷歌上搜索了很多解决方案，但没有运气。在docker-desktop [windows机器]中使用azure文件共享与kuberates容器有任何限制吗?

Answer 1

您可能需要安装一个知道如何挂载该文件系统的包。对于NFS，这可能是NFS -在Debian/Ubuntu中很常见。

sudo apt update && sudo apt install nfs-common -y

Answer 2

它发生在我的ubuntu服务器22.04 LTS机器上。用sudo apt install nfs-common或sudo apt install nfs-utils解决
