我有以下Chef食谱（web.rb）：
# Install Apache and start the service.
httpd_service 'customers' do
mpm 'prefork'
action [:create, :start]
end
# Add the site configuration.
httpd_config 'customers' do
instance 'customers'
source 'customers.conf.erb'
notifies :restart, 'httpd_service[customers]'
end
# Create the document root directory.
directory node['awesome_customers_ubuntu']['document_root'] do
recursive true
end
# Write the home page.
file "#{node['awesome_customers_ubuntu']['document_root']}/index.html" do
content '<html>This is a placeholder</html>'
mode '0644'
owner node['awesome_customers_ubuntu']['user']
group node['awesome_customers_ubuntu']['group']
end
我的default.rb食谱如下：
include_recipe 'apt::default'
include_recipe 'awesome_customers_ubuntu::firewall'
include_recipe 'awesome_customers_ubuntu::web_user'
include_recipe 'awesome_customers_ubuntu::web'
和attributes/default.rb：
default['firewall']['allow_ssh'] = true
default['awesome_customers_ubuntu']['open_ports'] = 80
default['awesome_customers_ubuntu']['user'] = 'web_admin'
default['awesome_customers_ubuntu']['group'] = 'web_admin'
default['awesome_customers_ubuntu']['document_root'] = '/var/www/customers/public_html'
当我执行kitchen converge时，我收到以下错误：
Recipe: awesome_customers_ubuntu::web

如何解决此问题？
答案 0 :(得分：1)
似乎在https://github.com/chef-cookbooks/httpd/blob/master/libraries/httpd_service_debian.rb#L8，package_name为nil。
跟踪此内容会导致https://github.com/chef-cookbooks/httpd/blob/master/libraries/httpd_service.rb#L23依赖于从https://github.com/chef-cookbooks/httpd/blob/master/libraries/info_service_packages.rb#L37延迟加载包名称
您可以通过明确声明您的资源来解决此问题：
httpd_service 'customers' do
mpm 'prefork'
package_name 'apache2'
action [:create, :start]
end
虽然，你真的不需要！也许提出错误？
