composer.phar安装问题（cloudinit vs manual）

Question

我正面临一个奇怪的问题。当厨师从用户数据（cloud-init）执行时，我的下面的厨师食谱失败。

它要求输入HOME/COMPOSER_HOME env变量。

但是，如果我从SSH终端运行手动厨师客户端（或者甚至直接在终端上运行命令），它运行良好。

PS：composer.phar和composer.json由开发商提供的（在WordPress拉链捆绑）

==配方片段==

# Install Composer 

script "install_composer" do 
    interpreter "bash" 
    user "root" 
    cwd "#{node.apache.default_docroot}/html" 
    code <<-EOH 
    /opt/rh/rh-php56/root/usr/bin/php composer.phar install 
    EOH 
    not_if {File.exists?("#{node.default_docroot}/html/composer.lock")} 
end 

==当从SSH终端运行==

* script[install_composer] action run 
    - execute "bash" "/tmp/chef-script20160722-5397-1sjwxg9"

添加environment HOME: '/root'您script资源（或类似）。这是必要的，因为厨师不会为你设置这个变量。当你通过SSH登录时，它会被你的登录shell设置，然后继承到chef-client进程。
