User defined parameters

Rudder provides a simple way to add common and reusable variables in either plain Directives, or techniques created using the Technique editor: the parameters.


The parameters enable the user to specify a content that can be put anywhere, using the following syntax:

  • In Directives: ${} will expand the content of the "name" parameter.
  • In the Technique Editor: ${} will do the same.

Using this, you can specify common file headers (this is the default parameter, "rudder_file_edit_header"), common DNS or domain names, backup servers, site-specific elements…
