Chef执行非顺序配方执行

Question

我按照教程http://gettingstartedwithchef.com/,第1章.

我的运行列表是

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

我的phpap cookbook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"

我的食谱的依赖性

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

我的回购已经下载了下载的食谱

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

我用厨师独奏.我的主人已经过时了回购信息.旧的回购不应该是一个问题,因为我的运行列表中的第一个配方更新它.但是厨师忽略了apt配方并从mysql开始.

主机运行ubuntu 12.04.我尝试在运行列表中将自己的食谱放在phpap之前但没有任何成功.

我可以在chef-solo之前手动在bash脚本中放置apt-get update来解决这个问题.

是mysql cookbook这么糟糕吗？据我所知,厨师总是沿着奔跑的海峡前进.

Answer 1

总的来说,厨师将始终尊重运行列表.但是,有时您可能希望在任何其他资源之前运行资源(比如配置包管理器,apt/yum/etc).mysql ruby​​配方中似乎发生的事情是配方在编译时显式运行一些软件包安装(在厨师开始执行资源之前).它们失败了,因为apt配方还没有运行(没有).

有一个很好的Opscode公司后解释编译/执行阶段在这里.

mysql :: ruby​​中的违规代码是

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

该run_action(:install)告诉厨师立即运行这个(在编译时).

Answer 2

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

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

但奇怪的行为却无法解释。
