As in, what is the impact of creating a dependency? When a resource depends on another resource, this means that the Heat engine will only start processing this resource as soon as the other resource it depends on has been created. If a resource depends on multiple resources, all those other resources have to be created before processing the depedent resource. > > I read http://docs.openstack.org/developer/heat/template_guide/ > hot_spec.html#resources-section and found this definition of the > “depends_on” attribute: > > > This optional attribute allows for specifying dependencies of the > current resource on one or more other resources.

I just checked the source in github and the section is there: https://github.com/openstack/heat/blob/master/doc/source/template_guide/hot_spec.rst#L452 It only looks like the wrong heading markup is used. Nice spotting actually; I will fix it. > > Thank you, > > Shaunak > _______________________________________________ > OpenStack-dev mailing list > OpenStack-dev at lists.openstack.org > http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev >
