macos - Vagrant 在 Vagrantfile 中找不到主机操作系统上的文件

Question

我试图在 Vagrantfile 中引用主机操作系统上的文件并设置环境变量。
但是，Vagrant 似乎无法找到该文件。
当引用与 Vagrantfile 位于同一目录中的文件时，一切正常。
1. Vagrantfile中Vagrant可以访问的文件是否仅限于VM目录？
2.是否可以在Vagrantfile中引用VM目录之外的文件(test1，test2，test3...)？ (例如/Users/hoge/vagrant/key.json)
我的项目和 Vagrantfile 如下。

/Users/hoge
  /vagrant
    - key.json

    /test1
      - Vagrantfile
      - provision.sh
      - /workspace

    /test2
      ...

    /test3
      ...

# -*- mode: ruby -*-
# vi: set ft=ruby :

Vagrant.configure("2") do |config|

  # Every Vagrant development environment requires a box. You can search for
  # boxes at https://vagrantcloud.com/search.
  config.vm.box = "ubuntu/bionic64"

  # Directory ./workspace needs to be made in advance, or error occurs.
  config.vm.synced_folder "./workspace", "/home/vagrant/workspace"

  # Provider-specific configuration so you can fine-tune various
  # backing providers for Vagrant. These expose provider-specific options.
  # Example for VirtualBox:
  #
  config.vm.provider "virtualbox" do |vb|
    # Display the VirtualBox GUI when booting the machine
    vb.gui = false

    # Customize the number of cpus on the VM:
    vb.cpus = "2"
    
    # Customize the amount of memory on the VM:
    vb.memory = "2048"

    vb.customize ["modifyvm", :id, "--ioapic", "on"]
  end
  #
  # View the documentation for the provider you are using for more
  # information on available options.

  # Enable provisioning with a shell script. Additional provisioners such as
  # Ansible, Chef, Docker, Puppet and Salt are also available. Please see the
  # documentation for more information about their specific syntax and use.

  config.vm.provision "shell", path: "./provision.sh", env: {"CLIENT_SECRET" => "$(base64 /Users/hoge/vagrant/key.json)"}
end

主机操作系统:MacOS Big Sur 11.5.1
guest 操作系统:Ubuntu 18.04 LTS(ubuntu/bionic64)
Vagrant 2.2.17
虚拟机 6.1.26

配置程序不在主机上执行，而是在虚拟机上运行(这就是为什么当您在 Vagrantfile 所在的 vagrant 目录中有文件时它会运行，因为该目录会自动与虚拟机上的 /vagrant 共享。
如果您想将文件保留在原处，您应该添加 file provisioner在 VM 上复制 key 文件，然后运行 ​​shell 配置程序
