install-docker-ubuntu1504.sh

# Usage: curl -H 'Cache-Control: no-cache' -s https://gist.githubusercontent.com/tsaqib/737607e64a1fba4d4562f2de21fd16d8/raw/ | sudo sh
# Works on: https://azure.microsoft.com/en-us/marketplace/partners/canonicalandmsopentech/dockeronubuntuserver1404lts/
# 'Docker on Ubuntu 15.04 LTS' works flawlessly on Azure's classical port mapping. If you map port 20001 from docker,
# you may easily map at Azure's Endpoints, for example public port = private port = 20001.
