在 Vagrantfile 中获取 vagrant 命令行参数 [英] getting the vagrant command line arguments inside the Vagrantfile

问题描述

我有以下配置只对 vagrant up 命令有意义:

I have the following configuration that only makes sense for vagrant up command:

config.vm.provider :virtualbox do |vb|
  vb.gui = false
  if ENV["VB_GUI"] == "true" then vb.gui = true
  else
     puts("[info] VB_GUI environment variable not set so running headless")
  end
end

是否可以挂钩 vagrant API 来检索当前正在执行的命令?例如

Is it possible to hook into the vagrant API to retrieve the command currently being executed? E.g.

config.vm.provider :virtualbox do |vb|
  vb.gui = false
  if VAGRANT_API.command == "up"  # how can I do this?
    if ENV["VB_GUI"] == "true" then vb.gui = true
    else
       puts("[info] VB_GUI environment variable not set so running headless")
    end
  end
end

推荐答案

Vagrantfile 只是 ruby​​ 代码，因此您可以使用 ARGV 数组轻松获取命令行参数.

A Vagrantfile is just ruby code so you can easily get the command line arguments using the ARGV array.

以下面的 vagrant 命令为例:

Take the following vagrant command for example:

vagrant up webserver

这将启动在您的 Vagrantfile 中定义为网络服务器的 Vagrant 框.然后您可以像这样访问参数:

That would start the Vagrant box defined as webserver in your Vagrantfile. You can then access the arguments like so:

ARGV[0] = up
ARGV[1] = webserver

因此，使用您的示例，您需要执行以下操作:

So using your example you need to do the following:

config.vm.provider :virtualbox do |vb|
  vb.gui = false
  if ARGV[0] == "up"
    if ENV["VB_GUI"] == "true" then vb.gui = true
    else
       puts("[info] VB_GUI environment variable not set so running headless")
    end
  end
end
