title: docker-compose creating multiple instances for the same image
body: <p>I need to start multiple containers for the same image. If i create my compose file as shown below, it works fine. </p>
  
  <pre><code>version: '2'
  
  services:
    app01:
      image: app
    app02:
      image: app
    app03:
      image: app
    app04:
      image: app
    app05:
      image: app  
  </code></pre>
  
  <p>Is there any easy way for me to mention the number of instances for the compose instead of copy and pasting multiple times?</p>
