Heat - Create volume and launch instance from it.
I was trying to write heat template for launch instance from volume, but no succseed.
Template:
heat_template_version: 2013-05-23
description: Test Template
parameters:
ImageID:
type: string
description: Image use to boot a server
NetID:
type: string
description: Network ID for the server
resources:
server1:
type: OS::Nova::Server
depends_on: volume1
properties:
name: "Ubuntu Node 01"
block_device_mapping: [{ device_name: "vda", volume_id : { get_resource : volume1 }, delete_on_termination : "true" }]
flavor: "m1.medium"
networks:
- network: { get_param: NetID }
volume1:
type: OS::Cinder::Volume
properties:
name : "Server 1 - Root Disk"
image : {"Ref": "ImageID"}
size : 1
Volume is created successfully, but instance not launched. For cinder volumes I use ceph backend.
In nova-compute log I was found this:

Your template looks OK (although
get_paramis preferable toRefin a HOT template). Have you tried this setup using the Nova and Cinder APIs directly? It seems likely that the problem may not be in Heat.What hypervisor are you running on your system ? What OS are you running on your compute node? As zaneb ask. Can you make an instance without Heat?
