Here is an example David. Not sure if this fits your use case well enough though.

cookbook_file "/etc/consul.d/common.json" do # This is the file that will be created
  source "sjc-common.json" # This is the file name in chef cookbook /files/default/ that will be used
  owner "consul"
  group "consul"
  mode "0644"
  action :create_if_missing
end
