I''m trying to write my first puppet template, but I am running into some issues. The following is my template: *# Managed by Puppet* *CONFIG_FILE=/etc/rabbitmq/rabbitmq* *<% if @rabbitmq_port != ''UNSET'' -%>* *NODE_PORT=<%= @rabbitmq_port %>* *<% end -%>* *<% if @rabbitmq_address != ''UNSET'' -%>* *NODE_IP_ADDRESS=<%= @rabbitmq_address %>* *<% end -%>* This is a pretty simply template, but the issue I''m seeing is that "NODE_PORT=" & "NODE_IP_ADDRESS=" is always printed into the config file regardless if the variables are set to UNSET or not. What I''m wanting to do is not print NODE_PORT= or NODE_IP_ADDRESS= if the matching variable is equal to UNSET. Output of configuration file when rabbitmq_port and rabbitmq_address are set to UNSET: *# Managed by Puppet* *CONFIG_FILE=/etc/rabbitmq/rabbitmq* *NODE_PORT=* *NODE_IP_ADDRESS=* * * Any help would be appreciated! -- You received this message because you are subscribed to the Google Groups "Puppet Users" group.

Could you show the puppet code that sets ''$rabbitmq_port'' and ''$rabbitmq_address'' ? I''d recommend dropping a line like this in your template: *NODE_PORT=<%= @rabbitmq_port.inspect %>* (If you see ''nil'', the variable either hasn''t been set or has been set to ''undef'').

If you are using hiera, you can set the default value to UNSET for those
variables, it should do it.
*rabbitmq_port =
hiera(''**rabbitmq_port'',''UNSET'')*
*
*
If you are using host facts, you can modify if condition like this:
*<% if **@rabbitmq_port != '''' and **@rabbitmq_port !=
''UNSET'' -%>*

Note that it does *not* contain NODE_PORT=UNSET NODE_IP_ADDRESS=UNSET , which is what you might expect it to print if the conditionals were somehow not working. The variables do not contain the values you think they do. My first guess would be that the Puppet variables you are trying to access from the template are neither global nor local to the scope in which the template is evaluated. Perhaps they belong to a parent scope. In particular, note that defined type bodies establish their own scopes. To my knowledge, defined-type instances do not inherit variables from the class that declares them (though they can reference class variables by all the normal mechanisms).
