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.

[openstack-dev] [Heat] Resource dependencies
Hi, In a Heat template, what does it mean for a resource to depend on another resource? As in, what is the impact of creating a dependency? 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. Please refer to section > hot_spec_resources_dependencies for details. Unfortunately, I can’t seem to find the referenced “hot_spec_resources_dependencies” section anywhere.
