我尝试将文件夹与boot2docker Vagrant框同步（在Windows 8.1上）：
Vagrantfile
# -*- mode: ruby -*-
# vi: set ft=ruby :
Vagrant.configure(2) do |config|
config.vm.hostname = "docker-host"
config.vm.box = "hashicorp/boot2docker"
config.vm.synced_folder "./src", "/sync/src"
end
我尝试了几种同步文件夹的方法：
如果我没有定义类型（如何同步），Vagrant使用SMB。所以就像我写的那样：
config.vm.synced_folder "./src", "/sync/src", type: "smb"
使用此配置安装失败（我输入我登录的Windows帐户的凭据）：

can work properly. The command attempted was:

如果我使用
config.vm.synced_folder "./src", "/sync/src", type: "nfs"
相反，Vagrant仍然使用 SMB （与之前相同的输出）。如果我使用
config.vm.synced_folder "./src", "/sync/src", type: "virtualbox"
我得到了

The synced folder type 'virtualbox' is reporting as unusable for
your current setup. Please verify you have all the proper
prerequisites for using this shared folder type and try again.
如果我使用
config.vm.synced_folder "./src", "/sync/src", type: "rsync"
安装 vagrant-gatling-rsync 插件
vagrant plugin install vagrant-gatling-rsync
并在Cygwin中运行（Cmd没有rsync），我明白了：

如何让文件夹同步与Vagrant和boot2docker一起运行？
答案 0 :(得分：0)
我在Windows上使用 dduportal / boot2docker 的工作设置如下所示：
# -*- mode: ruby -*-
# vi: set ft=ruby :
Vagrant.configure(2) do |config|
config.vm.hostname = "docker-host"
config.vm.box = "dduportal/boot2docker"
config.vm.provision "docker"
config.vm.synced_folder ".", "/vagrant", type: "virtualbox"
end
