title: How to set system variable from Spring Cloud Config Server
body: <p>I'm searching for a way to set system variables (e.g. -Djavax.net.ssl.keyStore) from <a href="https://cloud.spring.io/spring-cloud-config/" rel="nofollow noreferrer">Spring Cloud Config Server</a>, because I'm facing exactly this behaviour (<a href="https://stackoverflow.com/a/30199253/1406669">https://stackoverflow.com/a/30199253/1406669</a>) in a mutual ssl environment.<br/>
  There are various ways to set it statically (<a href="https://stackoverflow.com/a/36895827/1406669">https://stackoverflow.com/a/36895827/1406669</a> || <a href="https://gist.github.com/unamanic/a7eb0c17b78fb03617cc955b06285b1d" rel="nofollow noreferrer">https://gist.github.com/unamanic/a7eb0c17b78fb03617cc955b06285b1d</a>). <br/>The thing I don't like about it, is setting it statically (once set on startup and never refreshed) and the need to define the keys in a static way. In this way I would have to redeploy the apps when there would be the need to introduce a new system variable. This is a the thing I try to avoid.<br/>
  Does anybody got an idea?</p>
