title: Heroku Spring application.properties file
body: <p>I am hosting my Spring boot application on Heroku using git deploy. I have a public git repository and have added my application.properties file to the .gitignore as it contains sensitive details such as an api key and database credentials.</p>
  
  <p>What is the best way of handling this situation, am I able to upload the single application.properties file myself directly to Heroku? I don't want to use the Heroku config vars as I would rather stay platform independent.</p>
