title: Modify environment variables or configurations for a module on an IoT Edge deployment
body: <p>Is there a quick way to modify environment variables, or configurations (that is accessible) for a module in IoT Edge?
  Once a deployment is created, the environment variables become read only.
  What would be the best practice of maintaining a modifiable set of configurations, so I can rather easily change them on the fly, and have the module be able to access them?</p>
  
  <p>On Azure Cloud Services, for example, there are web configurations that are editable and would restart the service so they would kick in (since they are accessible to the service). I am looking for the same kind of behavior.</p>
