title: Add SSH-Key for nginx user (for github)
body: <p>I'm running into a bit of issues with nginx and SSH keys.</p>
  
  <p>I need to add a ssh key for the nginx user to access private github repositories and then run the "git ..." commands to pull or clone the repo onto my Ubuntu box.</p>
  
  <p>With the nginx user just being a worker task is it possible to generate a key for this user?</p>
  
  <p>Thanks for any help!</p>
