运行 厨师模板资源时如何保留现有主机文件
How to preserve existing host file when running chef template resource
我正在尝试使用 Chef 模板资源将一组新的 FQDN 和 IP 添加到现有的 Windows 主机文件中。我发现当我 运行 厨师食谱时，它会删除现有的主机文件，然后添加新的更新。我只想将新资源附加到文件末尾，我在这里使用 action :touch 做错了吗？
模板文件hosts.erb:
<% node['hostnames'].each do |name, value| %>
<%= value %>
<% end %>
食谱windows.rb文件：
template 'C:\Windows\system32\drivers\etc\hosts' do
source 'hosts.erb'
action :touch
end
kitchen converge 输出文件告诉我主机文件正在被覆盖而不是更新？为什么？
Recipe: hostnames::windows

这是大厨应有的行为。您有两个选择：1) 提供整个主机文件作为模板或 2) 使用 FileEdit class，例如 insert_line_if_no_match-instance_method.
