description: >
This is a default no-op template which provides empty user-data
which can be passed to the OS::Nova::Server resources.
This template can be replaced with a different implementation via
the resource registry, such that deployers may customize their
first-boot configuration.
resources:
userdata:
type: OS::Heat::MultipartMime
outputs:
# This means get_resource from the parent template will get the userdata, see:
# http://docs.openstack.org/developer/heat/template_guide/composition.html#making-your-template-resource-more-transparent
# Note this is new-for-kilo, an alternative is returning a value then using
# get_attr in the parent template instead.
OS::stack_id:
value: {get_resource: userdata}
