Attach existing volumes to heat instances
Hi there,
I have 'n' created volumes that I wish to attach to 'n' instances using heat. These volumes have a patterned name (volume_%id%).
I've created a template where the volumes are referenced as 'parameters' like :
parameters:
volume_00:
description: ID of the volume_00
label: volume_00 ID
type: string
default: d6ec3b01-8c9a-4677-842f-c1d054b1fa6c
volume_01:
description: (...)
On the other hand, the resources are created with :
resources:
port_00:
type: OS::Neutron::Port
properties:
network: { get_param: network_name }
fixed_ips:
- subnet_id: { get_param: subnet_name }
instance_00:
type: OS::Nova::Server
properties:
key_name: { get_param: key_name }
image: { get_param: image_id }
flavor: { get_param: flavor_id }
networks:
- port: { get_resource: port_00 }
volume_attachment_00:
type: OS::Cinder::VolumeAttachment
properties:
volume_id: { get_param: volume_00 }
instance_uuid: { get_resource: instance_00 }
mountpoint: { get_param: mount_point }
Instead of rewriting 'n' times these statements, can I populate a file with the IDs (from 00 to 'n') and the corresponding volume_ids that can be used with a "repeat" statement to generate 'n' instances ? I can put the resources in a nested template, but how can I get the volume ids from a file to be sourced as the template parameters ?
Any help, suggestion appreciated :)
Regards
