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

Using IP address of one VM with-in another VM
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] }
