Export and configurations

During delivery of source code to a Staging or Live environment some of the environment configurations need to be different. For example, API keys for different connectors and SMTP server settings, which is necessary because you do not want to spam the live accounts with test data.

Continuous delivery automates the delivery of configurations from Development to Live environments. This way, you do not need to manually apply transformation to configurations.

• Environment configurations
  Environment configurations are delivered with the source code and, therefore, must not be saved in the database. This is because, database is never pushed from Development to Test or Live environments. It is pulled from Live, so that new code changes can be tested against actual live application data.

  NOTE: Labels and messages (resource files) are stored as configurations and not in the database. Therefore, changes to them should pass through the continuous delivery process and not be done on your live environment.        

• Application settings
  On the other hand, there are the application configurations that need to be changed during runtime. Application configuration is a setting that is related to the applications actual functionality and is modified on the Live environment runtime. These settings need to be saved in the database, so that they are not overwritten with each subsequent delivery of code.

The following flowchart demonstrates the flow of code and database:
