I am trying to create a stack using this template:

heat_template_version: 2013-05-23

description: Simple template to deploy a single compute instance

    type: OS::Nova::Server
      key_name: Key1
      image: ubuntu14.04
      flavor: m1.small

But the stack fails to create with this error:

Resource CREATE failed: BadRequest: Multiple possible networks found, use a Network ID to be more specific.

Please help me resolve the issue.

P.S. I am not sure wether ubuntu14.04 image is cfn-tools-enabled image or not. Would it matter?

Regarding your question of cfn-tools-enabled image, if you are using the user data scripts then you need cfn-tools because it uses it for injectiing the scripts, so that you get a VM pre-configured with whatever configs you want

Hi, this error is because you got more than 1 network available in your project, you need to specify in the stack's YAML the propertie

          - network: <Network name or UUID>

Saved my bacon on this :-) Had a question though. When using this resources: wordpress_instance: type: OS::Nova::Server properties: image: { get_param: image_id } flavor: { get_param: instance_type } key_name: { get_param: key_name } networks: - network: 64304f40-a0c1-4ec9-8125-ca5309698266 user_data: Should you use your Private address ID then add your Public Floating to the instance or should you add Both Priv and Pub here? And again thanks for the very much needed tip!!
