Question

Chef似乎正在以奇怪的顺序处理资源，导致我的构建失败。我的主要食谱（mytardis-chef/site-cookbooks/recipes/default.rb）开头是这样的：

include_recipe "build-essential"
include_recipe "mytardis::deps"
include_recipe "mytardis::nginx"
include_recipe "mytardis::postgresql"

mytardis-chef/cookbooks/build-essential/recipes/default.rb看起来像这样：

case node['platform']
when "ubuntu","debian"
  %w{build-essential binutils-doc}.each do |pkg|
    package pkg do
      action :install
    end
  end
when "centos","redhat","fedora","scientific"
  %w{gcc gcc-c++ kernel-devel make}.each do |pkg|
    package pkg do
      action :install
    end
  end
end

...（这是https://github.com/opscode-cookbooks/build-essential/blob/master/recipes/default.rb的旧版本）

在运行时，出于我不理解的原因，这个构建必需的配方会被加载但不会被执行：

也就是说，构建必需的配方是“找到”和“加载”，但它是首先被“处理”的postgres配方。由于build-essential（安装C编译器）没有运行，后者失败了。

我的Vagrantfile的相关部分如下所示：

  config.vm.provision :chef_solo do |chef|
     chef.log_level = :debug
     chef.cookbooks_path = ["mytardis-chef/site-cookbooks", "mytardis-chef/cookbooks"]
     chef.roles_path = "mytardis-chef/roles"
     chef.data_bags_path = "mytardis-chef/data_bags"
     chef.add_recipe "mytardis"    
  end

我之前使用的是早期版本的Chef（也许是10.10.0？）在那个版本中，build-essential也没有运行，但mytardis :: deps是。现在使用Chef 10.12.0。物理机是OSX，VM是Ubuntu Lucid。

所以，有几个问题：

为什么build-essential不被“处理”？
这样做的正确方法是什么？（我没有写这些食谱，我知道他们为他们的作者做过或曾经为他们工作过。）
网站烹饪书和烹饪书的“阴影”功能是否仍然有效？它应该被弃用：http://tickets.opscode.com/browse/CHEF-2308（我尝试在site-cookbooks / mytardis / recipes / build-essential下创建一个符号链接，但没有欢乐）。

Answer 1

事实证明，这是一个非常正常（但记录不足）的部分，如何使用Chef：它编译所有内容，然后开始运行。除了一些食谱（如Postgres）之外，使用以下代码跳转队列以在编译时实际安装：

  action :nothing
end.run_action(:run)

解决方案是在Postgres之前需要运行的任何事情都需要这样做。幸运的是，较新版本的Build-essentials允许这样做。您可以按如下方式在角色上设置属性：

name "myapp"
run_list(
  "recipe[build-essential]",
  "recipe[myapp]"
)
default_attributes(
  "build_essential" => {
    "compiletime" => true
  }
)

Answer 2

如果要编写食谱，请将属性添加到属性文件中：

node.default['build_essential']['compiletime'] = true
