Question

我正在尝试使用Chef在Wordpress多站点前设置Varnish。我是其他人建立的系统的新手，我是一个普通的初学者。

我创建了一个新配方并将其添加到运行列表中，但是当我运行chef-client时，它会执行一个不同的配方来代替我写的那个。具体来说，它运行我的食谱包含的唯一配方。

这是我的食谱，我几乎逐字逐句地复制了我们用于不同网站的预先存在的工作方法：

#
# Cookbook Name:: web_varnish_config
# Recipe:: wordpress
#

include_recipe 'web_varnish_config::default'

all_wordpress_backends = search(:node, "chef_environment:#{node.chef_environment} AND roles:web_wordpress")
all_wordpress_backends.sort_by!{ |n| n[:fqdn] } # Sort the nodes to prevent config-order thrashing.

# Error state
if all_wordpress_backends.empty?
  Chef::Log.warn("At least one node with recipes:web_wordpress must exist for chef_environment:#{node.chef_environment}. Skipping Varnish configuration.")
  return
end

template "/etc/varnish/default.vcl" do
  source "etc/varnish/wordpress.vcl.erb"
  mode "0644"
  variables(
    :all_wordpress_backends => all_wordpress_backends
  )
  notifies :restart, "service[varnish]", :delayed
end

# Use a share secret for our Varnish instances that is available to our Webservers
# so that Wordpress can clear the Varnish cache.
include_recipe 'chef-vault'
settings = chef_vault_item_for_environment("web_wordpress", "varnish")
if !settings.nil? and settings.key?('secret')
  file "/etc/varnish/secret" do
    content settings['secret']
    mode "0600"
    notifies :restart, "service[varnish]", :delayed
  end
end

当我运行chef-client时，它运行web_varnish_config :: default而不是这个食谱，web_varnish_config :: wordpress。这就是我的厨师 - 客户端输出的样子（试图复制所有内容，但不能这样，这是开始和结束，我认为最相关）：

最后：

Recipe: web_varnish_config::backend

   * web_apache_config_vhost[vhost-7-wwwhealthcheck.conf] action create
   * template[/etc/httpd/conf.d/vhost-7-wwwhealthcheck.conf] action create (up to date)
 (up to date)
 # NOTE: Below is where I'm expecting web_varnish_config:wordpress
 Recipe: web_varnish_config::default
   * service[varnish] action enable (up to date)
   * template[/etc/varnish/varnish.params] action create (up to date)
   * service[varnishncsa] action enable (up to date)
   * service[varnishncsa] action start (up to date)
   * cookbook_file[/etc/systemd/system/varnishncsa.service] action create (up to date)

如果我拿出包含行，那么chef-client会完全跳过它，没有错误。

有什么想法吗？

Answer 1

从评论中复制下来，配方中的搜索很可能不会返回任何节点，因此配方会在写入时自动跳过。

Answer 2

事实证明我忘了更新角色的名称：

# I needed to change roles:web_wordpress to roles:web_wordpress_new
all_wordpress_backends = search(:node, "chef_environment:#{node.chef_environment} AND roles:web_wordpress")

这意味着我的问题非常具体，可能对其他人没有帮助，但确实如此。

厨师运行错误的食谱
