Chef: template 'name' from variable?

I have an attribute in attributes/default.rb:

default["host_name"] = "domain.com"

And want to create NGINX's config with hostname from that attribute:

...
template "/etc/nginx/conf.d/#{@host_name}.conf" do
  source 'domain.conf.erb'
  owner 'root'
  group 'root'
  mode '0644'
end
...

But during build - Chef can't see host_name:

 ...
 [14:18:28][Step 1/1] Recipe: nginx_proxy::default
 [14:18:28][Step 1/1]   * template[/etc/nginx/conf.d/.conf] action create
 [14:18:28][Step 1/1]     - create new file /etc/nginx/conf.d/.conf
 [14:18:28][Step 1/1]     - update content in file /etc/nginx/conf.d/.conf rom none to cc9a26
 ...

What's wrong here? Can it be achieved at all?

Chef docs don't say anything about "dynamic" name for template.

You need to use the node object to access its attributes. What you are try to accessing with @host_name is a local variable.

The following should work:

template "/etc/nginx/conf.d/#{node['host_name']}.conf" do
  source 'domain.conf.erb'
  owner 'root'
  group 'root'
  mode '0644'
end
