Posted to Use Rails 4 secrets.yml for database config over 1 year ago

We use this technique for the simplicity of having a single source of truth for all app configuration that's easy to manage & reason about.

We deploy with our apps with Docker & use Chef to provision the metal.

  • The canonical source of secrets.yml lives in our Chef setup
  • Chef copies the secrets.yml file to all servers in the cluster
  • Docker containers mount the directory where secrets.yml is kept
  • On startup, the containers copy secrets.yml to APP/config/secrets.yml then start the app

It's working nicely for us & removes the cognitive load of having configs spread across multiple files & environment variables. YMMV
