  (Asked by: username_0 on 2019-02-10)
  
  I want to setup an auto-scaling configuration but cannot think how I can securely get code from a private repo when I spin up new instances.
  
  I obviously don't want to put passwords in startup scripts, or store private keys somewhere that can be downloaded without a password.
  
  How can I achieve this?

  Another option is to use saltstack's product: salt
  
  This Configuration Management System (CMS) can protect sensitive data in three ways.
  
  1) Pillars; these are securely stored and encrypted key:value or key:list dictionaries stored on your primary computer(s) that you manage the entire cluster from.
  
  This will allow you to create salt scripts that can have that data inserted at time of running into the scripts (so not stored in the actual scripts).
  
  2) GPG cipher; this allows you to write in actual passwords and keys into scripts and have them encrypted into hashes as placeholders for when you store these scripts into a revision control system (github/gitlab/bitbucket).
  
  The GPG key used for encrypting/decrypting is stored on your primary computer (master) for managing the cluster.
  
  3) Salt-cloud; all of your salt scripts are stored in the `/srv/salt/` directory on the primary machine, however the credentials/keys for spinning up VMs in the cloud is stored in `/etc/salt/` directory.
  
  This allows you to store the work you share with other people on a project in github, but all the sensitive data salt needs to spin up more resources isnt even in the same directory to be recorded.
