I'm pretty sure it is useful to model images in Heat.
Consider this scenario:
resources:
build_done_handle:
type: AWS::CloudFormation::WaitConditionHandle
build_done:
type: AWS::CloudFormation::WaitCondition
properties:
handle: {Ref: build_done_handle}
build_server:
type: OS::Nova::Server
properties:
image: build-server-image
userdata:
join [ "",
- "#!/bin/bash\n"
- "build_an_image\n"
- "cfn-signal -s SUCCESS "
- {Ref: build_done_handle}
- "\n"]
built_image:
type: OS::Glance::Image
depends_on: build_done
properties:
fetch_url: join [ "", ["http://";, {get_attribute: [ build_server,
fixed_ip ]}, "/image_path"]]
actual_server:
type: OS::Nova::Server
properties:
image: {Ref: built_image}
Anyway, seems rather useful. Maybe I'm reaching.
