My json config file

Notice that java, elasticsearch and rabbitmq are already set up in my system.

        }
    }
}

The local cookbook

Notice that the config references a logstash-local cookbook. The default recipe have a couple of generic config, but we need more. This is where I keep my .conf.erb.

$ mkdir site-coobooks/logstash-local
$ cp -R cookbooks/logstash/templates site-cookbooks/logstash-local
$ cat > site-cookbooks/logstash-local/metadata.rb 
name             'logstash-local'
description      'templates for logstash config'
^D

Templates are now in site-cookbooks/logstash-local/templates/default/config/

My rabbit conf template

For completeness here's my version of input_rabbitmq.conf.erb

input {
  rabbitmq {
    exchange => "logstash"
    durable => true
<% if @rabbitmq_host -%>
    host => "<%= @rabbitmq_host %>"
<% end -%>
<% if @rabbitmq_vhost -%>
    vhost => "<%= @rabbitmq_vhost %>"
<% end -%>
<% if @rabbitmq_user -%>
    user => "<%= @rabbitmq_user %>"
<% end -%>
<% if @rabbitmq_password -%>
    password => "<%= @rabbitmq_password %>"
<% end -%>
  }
}
