heat_template_version: 2013-05-23
description: >
A template to test host assignment for translated hot resources.
It makes sure if a resource depends on multiple hosts only the
one with the "HostedOn" relationship is picked as the host. In
this template, the translated resource 'app_collectd_create_deploy'
would depend on 'logstash_server' and 'app_server'. But it would
have "HostedOn" relationship with 'app_server', and that server
would be its host.
