问题描述

Chef似乎正在以奇怪的顺序处理资源，导致构建失败。我的主要食谱（ mytardis-chef / site-cookbooks / recipes / default.rb ）开始如下：

Chef seems to be processing resources in a strange order, causing my build to fail. My main recipe (mytardis-chef/site-cookbooks/recipes/default.rb) starts like this:

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 的较旧版本）

... (it's an older version of https://github.com/opscode-cookbooks/build-essential/blob/master/recipes/default.rb)

在运行时，由于我不明白的原因，此构建必需的配方已加载但未执行：

At runtime, for reasons I don't understand, this build-essential recipe gets loaded but not executed:

基本配方是找到并加载的，但首先要对 postgres配方进行处理。而且由于未运行build-essential（安装C编译器），因此后者失败。

That is, the build-essential recipe is "found" and "loaded", but it's the postgres recipe that gets "processed" first. And since build-essential (which installs the C compiler) wasn't run, the latter fails.

我的Vagrantfile的相关部分如下所示：

The relevant part of my Vagrantfile looks like this:

  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

我以前使用的是Chef的稍早版本（也许是10.10.0？），在那个版本中，build-essential也没有运行，但是mytardis :: deps在运行。现在使用Chef 10.12.0。物理机是OSX，虚拟机是Ubuntu Lucid。

I was previously using a slightly earlier version of Chef (perhaps 10.10.0?) In that version, build-essential was also not being run, but mytardis::deps was. Now using Chef 10.12.0. Physical machine is OSX, VM is Ubuntu Lucid.

因此，有几个问题：


  1. 为什么没有对 build-essential进行处理？

  2. 执行此操作的正确方法是什么？ （我没有写这些食谱，我了解它们已经或为他们的作者工作过。）

  3. 站点烹饪书和食谱的阴影功能是否仍然可以使用？据推测，它已被弃用： http://tickets.opscode.com/browse/CHEF-2308 （我尝试制作一个符号链接来自site-cookbooks / mytardis / recipes / build-essential，但没有乐趣）。

  1. Why is build-essential not being "processed"?
  2. What's the right way to do this? (I didn't write these recipes, and I understand they do or have worked for their author.)
  3. Should the site-cookbooks and cookbooks 'shadowing' feature still work? It's supposedly deprecated: http://tickets.opscode.com/browse/CHEF-2308 (I tried making a symbolic link under from site-cookbooks/mytardis/recipes/build-essential but no joy).


推荐答案

事实证明，这是Chef工作方式的一个非常正常的部分（但文献不足）：它会编译所有内容，然后 then 开始运行。除了某些食谱（例如Postgres）之外，使用以下代码跳过了在编译时实际安装的队列：

It turns out this is a pretty normal (but under-documented) part of how Chef works: it compiles everything, and then starts running. Except some recipes (like Postgres) jump the queue to actually install at compile-time, using code like this:

  action :nothing
end.run_action(:run)

解决方案是任何需要运行的内容Postgres也需要这样做。幸运的是， Build-essentials 的较新版本允许这样做。您可以按如下所示设置角色的属性：

The solution is that anything that needs to run before Postgres also needs to do this. Fortunately, newer versions of Build-essentials allow this. You set attributes on a role as follows:

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