Basic cloud-config for Debian - NOT WORKING!

I’ striving to get a working template of a #cloud-config file for Debian (Wheezy) - I have the following ATM:

#-------------------------------
#!/bin/bash 
# - add wheezy-backports  
echo "deb http://cdn.debian.net/debian wheezy-backports main" > /etc/apt/sources.list.d/wheezy-full.list
apt-get -y update && apt-get -y upgrade
apt-get install -y apache2 haproxy php5 php5-memcached php5-mysqlnd php5-adodb php5-gd php-apc php5-pgsql rubygems ruby-full rkhunter lynis htop mc tmux rcconf tree nload screen nmap 
 #DigitalOcean Specific GET HOST details
export HOSTNAME=$(curl -s http://169.254.169.254/metadata/v1/hostname)
export PUBLIC_IPV4=$(curl -s http://169.254.169.254/metadata/v1/interfaces/public/0/ipv4/address)
echo "created @ $(date) local machine time <br> $HOSTNAME, IP Address: $PUBLIC_IPV4 <br> THANK YOU! cloud-config." > /var/www/index.html

However it seems to be having no effect when entering it within “User Data” upon Droplet creation. Using the API’s I’m able to see that the “User-Data” is indeed registered.

I’ve also tried the above with other cloud-config yaml blocks eg:

#cloud-config
disable_root: false
manage_etc_hosts: true
#.
#.
#.
runcmd:
 - echo "deb http://cdn.debian.net/debian wheezy-backports main" > /etc/apt/sources.list.d/wheezy-full.list
 - apt-get -y update
#.

But no luck.

Any suggestions / help would be well appreciated.
