I'm trying to add new set of FQDN and IPs into the existing Windows hosts file by using the Chef template resources. What I found out is when I ran the chef recipe it will erase the existing hosts file and then add the new updates. I only want to append the new resources to the end of the file, am I doing something wrong here by using action :touch
?
template file hosts.erb:
<% node['hostnames'].each do |name, value| %>
<%= value %>
<% end %>
recipe windows.rb file:
template 'C:\\Windows\\system32\\drivers\\etc\\hosts' do
source 'hosts.erb'
action :touch
end
kitchen converge output file tells me the hosts file is getting overwritten and not update? why?
Recipe: hostnames::windows
* template[C:\Windows\system32\drivers\etc\hosts] action touch

This is proper Chef's behavior. You have two options: 1) Provide whole hosts file as atemplate or 2) Use FileEdit class, for example insert_line_if_no_match-instance_method.
