title: ECR - What is the registry and what is a repository
body: <p>Trying to familiarize myself with ECR - i understand that you should be able to push as many repositories as you like to Docker registry.</p>
  
  <p>However, ECR has a concept of a 'repository'.
  So if i have 10 different containers comprising my app, does it mean i need 10 repositories in a registry? </p>
  
  <p>Can i have one repository and push 10 different containers with their 'latest' tags?</p>
  
  <p>Currently if i tag another image with the same {registry}/{repository_name} pattern, it replaces <code>latest</code> tag on my other image:</p>
