composer.phar安裝問題（cloudinit vs manual）

Question

我正面臨一個奇怪的問題。當廚師從用戶數據（cloud-init）執行時，我的下面的廚師食譜失敗。

它要求輸入HOME/COMPOSER_HOME env變量。

但是，如果我從SSH終端運行手動廚師客戶端（或者甚至直接在終端上運行命令），它運行良好。

PS：composer.phar和composer.json由開發商提供的（在WordPress拉鍊捆綁）

==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 

==當從SSH終端運行==

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

添加environment HOME: '/root'您script資源（或類似）。這是必要的，因爲廚師不會爲你設置這個變量。當你通過SSH登錄時，它會被你的登錄shell設置，然後繼承到chef-client進程。
