+We recommend using the `.pkrtpl.hcl` file extension when using the `templatefile` function to create templates. Packer treats HCL templates as combination of file and template. As a result, HCL template files have slightly different set of features than the templates with a `.pkr.hcl` extension. Using the `.pkr.hcl` extension also enables syntax highlighters to properly understand your file.

 The template syntax is the same as for string templates in the main HCL2
 language, including interpolation sequences delimited with `${ ... }`. This
 function just allows longer template sequences to be factored out into a
