title: How can I sync a script on many servers without the need to manually pull, like you would do with git?
body: <p>Currently, I have 6 servers which are running nearly the same nodejs script, they only differ in the database credentials. I frequently make changes to that script and to deploy the changes to all servers, I need to ssh on to all of them and pull all the changes.</p>
  
  <p>Is there a better way to do this?</p>
