Applications running on Lens AppIQ have the capability of using environment variables to handle configurations. For example, if users need to connect with a third-party service like the Twitter API, the application will potentially need things like an api_key.

Using Lens AppIQ, the recommended way to expose these values to applications is by using environment variables. To make this easy, Lens AppIQ provides options to set and get environment variables in a running application through the dashboard and CLI, as described below.

When setting environment variables, there following options are presented:
