ruby - Chef 执行非顺序配方执行

Question

我遵循教程http://gettingstartedwithchef.com/，第 1 章。

我的跑步清单是

  "run_list": [ "recipe[apt]", "recipe[phpap]" ]

我的 phpap 食谱的默认食谱

include_recipe "apache2"
include_recipe "build-essential"
include_recipe "openssl"
include_recipe "mysql::client"
include_recipe "mysql::server"
include_recipe "php"
include_recipe "php::module_mysql"
include_recipe "apache2::mod_php5"    
include_recipe "mysql::ruby"

我的食谱的依赖项

depends "apache2"
depends "mysql"
depends "php"
depends "database"

我的仓库有以下下载的食谱

apache2  aws              database  openssl  phpap    xml
apt      build-essential         mysql  php      postgresql  xfs

我用厨师独奏。我的主机已过时 apt repo 信息。旧的 apt repo 应该不是问题，因为我的运行列表中的第一个配方会更新它。但是厨师忽略了 apt recipe 并从 mysql one 开始。

主机运行 ubuntu 12.04。我试图将我自己的食谱放在运行列表中的 phpap 之前，但没有任何成功。

我可以通过在 chef-solo 之前手动将 apt-get update 放入 bash 脚本来解决这个问题。

mysql 食谱有这么差吗？据我所知，厨师总是遵循运行列表海峡前进。

Answer 1

一般来说，厨师将永远尊重运行列表。但是，有时您可能希望在任何其他资源之前运行资源（例如配置包管理器，apt/yum/等）。mysql ruby​​ 配方中似乎发生的事情是该配方在编译时显式运行一些包安装（在厨师开始执行资源之前）。他们失败了，因为 apt 配方还没有运行（没有）。

有一篇很好的 opscode 帖子在这里解释了编译/执行阶段。

mysql::ruby 中的违规代码是

node['mysql']['client']['packages'].each do |name|
  resources("package[#{name}]").run_action(:install)
end

run_action(:install)告诉厨师现在运行它（在编译时）。

Answer 2

我在裸 ubuntu 12.04（没有任何手动预更新）上获得了没有失败的 phpap 配方，并进行了以下修复。

我从 phpap 一中删除了食谱“build-essential”和“openssl”。更改后，厨师按预期执行食谱。

但是奇怪的行为无法解释。

Answer 3

vagrant destroy -f && vagrant up // destroy everything and start over => OK
