linux - 在 Docker for Windows 中创建符号链接(symbolic link)失败，还不支持吗？

Question

我有一个运行 Ubuntu Server 的 docker 容器。我正在运行适用于 Windows 的 Docker，并且分别安装了以下版本的 Docker 和 Docker Compose:

> docker-compose -v
docker-compose version 1.11.2, build f963d76f

> docker -v
Docker version 17.03.1-ce-rc1, build 3476dbf

这是我到目前为止没有成功的尝试:

// The dojo linked file exists so I've tried to update it as per this answer (http://stackoverflow.com/a/1951752/719427)
> docker exec -it dockeramp_webserver_1 ln -sf /var/www/html/externals/dojo /var/www/html/externals/public_html/js/dojo
ln: failed to create symbolic link '/var/www/html/externals/public_html/js/dojo': No such file or directory

// I have deleted the previous linked file and then I tried to create a new one
> docker exec -it dockeramp_webserver_1 ln -s /var/www/html/externals/dojo /var/www/html/externals/public_html/js/dojo
ln: failed to create symbolic link '/var/www/html/externals/public_html/js/dojo': No such file or directory

// removed the directory name from the link name
> docker exec -it dockeramp_webserver_1 ln -s /var/www/html/externals/dojo /var/www/html/externals/public_html/js    
ln: failed to create symbolic link '/var/www/html/externals/public_html/js': No such file or directory

因为报错一直说目录不存在所以我查了一下报错是对还是错:

> docker exec -u www-data -it dockeramp_webserver_1 ls -la /var/www/html/externals/dojo

-rwxr-xr-x 1 root root 6141 Mar 25 15:11 quoteit_delegate_search.js

它们都存在，所以……我在这里缺少什么？ Windows 还不支持它吗？我发现开发团队添加了一个名为 mfsymlinks 的东西比我的版本早。

该命令告诉您 /var/www/html/externals/public_html 不存在。您只显示了 /var/www/html/externals/dojo 和 /var/www/html/public_html/js 文件夹存在。我相信这是您命令中的一个简单错字。
