title: Fail fast if a Spring application cannot connect to its config server
body: <p>Consider you have a Spring application that gets its configuration from a config server. If it cannot connect to the config server, the application will continue to start but as all configurations are missing, it will eventually fail with a potentially misleading error.</p>
  
  <p>Is it possible to configure Spring, so it immediately aborts when it cannot connect to its config server during startup?</p>
