Question

我想知道在使用Vagrant创建多机环境时是否有办法为配置程序指定默认值？

我试图做以下事情：

Vagrant.configure("2") do |config|
  config.vm.box = "andyshinn/ubuntu-precise64"

  config.vm.provision :chef_client do |chef|
    chef.chef_server_url = "https://api.opscode.com/organizations/myorg"
    chef.validation_key_path = "~/.chef/myorg-validator.pem"
    chef.delete_node = true
    chef.delete_client = true
    chef.validation_client_name = "myorg-validator"
  end

  config.vm.define :app do |app|
    app.vm.network "private_network", ip: "172.16.64.61"
    app.vm.host_name = "vagrant-app-#{ENV['USER']}"

    app.vm.provision :chef_client do |chef|
      chef.add_recipe "myrecipe1"
      chef.add_recipe "myrecipe2"
      chef.add_recipe "sudo"
    end
  end

  config.vm.define :web do |web|
    web.vm.network "private_network", ip: "172.16.64.62"
    web.vm.host_name = "vagrant-web-#{ENV['USER']}"

    web.vm.provision :chef_client do |chef|
      chef.add_recipe "myrecipe3"
      chef.add_recipe "myrecipe4"
      chef.add_recipe "sudo"
    end
  end
end

但是每个VM块似乎都没有获取任何主配置块设置。我收到这个错误：

There are errors in the configuration of this machine. Please fix
the following errors and try again:

chef client provisioner:
* Chef server URL must be populated.
* Validation key path must be valid path to your chef server validation key.

可以通过其他方法吗？

您的问题属于范围之一。变量chef在config.vm.provision do块中具有块范围。

一旦此块退出，您的更改就会消失。您应该遵循流浪网站上的multi-machine文档中的示例。

config.vm.provision "shell", inline: "echo Hello"

Vagrant.configure("2") do |config|
  config.vm.box = "andyshinn/ubuntu-precise64"


  config.vm.provision "chef_client", chef_server_url: "https://api.opscode.com/organizations/myorg"
  config.vm.provision "chef_client", validation_key_path:  "~/.chef/myorg-validator.pem                
  config.vm.provision "chef_client", delete_node: true
  config.vm.provision "chef_client", delete_client: true
  config.vm.provision "chef_client", validation_client_name: "myorg-validator"


  config.vm.define :app do |app|
    app.vm.network "private_network", ip: "172.16.64.61"
    app.vm.host_name = "vagrant-app-#{ENV['USER']}"

    app.vm.provision :chef_client do |chef|
      chef.add_recipe "myrecipe1"
      chef.add_recipe "myrecipe2"
      chef.add_recipe "sudo"
    end
  end

应该做的伎俩

也许你已经有了这个工作，但如果没有，请检查一下：

它部分解决了我的问题;也许它会帮助你。

我认为内部块“覆盖”外部块。但是，你可以做一些事情，比如我最终在我的答案（我自己的问题）中假装inside out ordering of provisioners而不是像Vagrant提供的那样从外到。在你的情况下，你不会像我一样拥有一个shell和puppet供应商，但是你应用类似template method模式的东西来扩展一个厨师供应商的食谱。也许是这样的事情：

module Vagrant
  module Config
    module V2
      class Root
        def provision(extra_recipes)
          config.vm.provision :chef_client do |chef|
            chef.chef_server_url = "https://api.opscode.com/organizations/myorg"
            chef.validation_key_path = "~/.chef/myorg-validator.pem"
            chef.delete_node = true
            chef.delete_client = true
            chef.validation_client_name = "myorg-validator"
            extra_recipes.each { |recipe| chef.add_recipe(recipe) }
          end
        end
      end
    end
  end
end

Vagrant.configure("2") do |config|
  config.vm.box = "andyshinn/ubuntu-precise64"

  config.vm.define :app do |app|
    app.vm.network "private_network", ip: "172.16.64.61"
    app.vm.host_name = "vagrant-app-#{ENV['USER']}"

    app.provision("myrecipe1", "myrecipe2", "sudo")
  end

  config.vm.define :web do |web|
    web.vm.network "private_network", ip: "172.16.64.62"
    web.vm.host_name = "vagrant-web-#{ENV['USER']}"

    app.provision("myrecipe3", "myrecipe4", "sudo")
  end
end
