Does the images need to have cloud-init pre-installed for user_data section to work?

Just to add another point I am using docker container here as the image. Can that be a issue.

Hello,

Somehow I see that user data section is not working for me. Rest all works fine  Here is a simple template.

heat_template_version: 2013-05-23
description: A simple server.
resources:
  server:
    type: OS::Nova::Server
    properties:
      flavor: m1.tiny
      networks:
        - network: demo-net
      key_name: demo-key-new
      image: httpd
      user_data:
        #!/bin/bash
        mkdir -p /opt/test
        touch /usr/bin/test/1.txt
        echo "hello" >> /usr/bin/test/1.txt

outputs:
  HttpIP:
    description: IP of HTTP server
    value:
      str_replace:
        template: http://host
      params:
        host: { get_attr: [server, first_address] }

Regards
Ashish

Yes.  As an example take a look at
"https://github.com/openstack/heat-templates/blob/master/hot/F20/WordPress_2_Instances.yaml".

The "WebServer" is configured with the IP address of the "DatabaseServer":

db_ipaddr: { get_attr: [DatabaseServer, networks, private, 0] }
