Variable reference

May 24, 2018

When you use the repeat and repeat-item constructs in components to build multiple configuration objects, you can assign a variable name to the repeat-item construct. This variable can be then referenced in the properties of that component or in child components by using the notation $<varname>. Note that when the repeat construct is used without the repeat-item construct in a component, a default variable called $repeat-item can be used to access the iteration items.




       name: server-members-comp

       type: ns::server

       condition: $parameters.svc-server-domain-names

       repeat: $parameters.svc-server-domain-names

       repeat-item: server-name


            name: $server-name + "-server"

            domain: $server-name



              name: service-members-comp

              type: ns::service


                     name: $server-name + "-service"

                     servername: $

                     servicetype: $parameters.svc-service-type

                     port: $parameters.svc-server-port

In the above example, a variable name, server-name, is assigned to the repeat-item construct. This variable name is referred to in the properties of the same component as well as in the child components $<varname>.
