title: One App -> Run Multiple Docker Instances on Single Ec2
body: <p>I have an application , say an api , running as docker container on ec2.
  As this container has dependency on the ec2 host ( port mapping) , i am unable to run more than one instance in a same machine.</p>
  
  <p>I want to achieve a state where i have 5 hosts which are fronted with an elb and i should be able to run more than 1 instance of the container in all these hosts.</p>
  
  <p>I am aware that i can achieve this state using ECS.</p>
  
  <p>Can i do this with Ec2 , ELB and Docker? </p>
  
  <p>-Thanks</p>
