App Configuration Management

Note: The information in this section is applicable for an app executable only.

Flogo allows you to externalize app configuration using app properties so that you can run the same app in different environments without modifying your app. It integrates with configuration management systems such as Consul, SNAPSHOT, and AWS Systems Manager Parameter Store to get the values of app properties at runtime.

You can switch between configuration management systems without modifying your app. You can do this by running the configuration-management-system-specific environment variable from the Data Plane. Since the environment variables are set for the specific configuration management system, at runtime, the app connects to that specific configuration management system to pull the values for the app properties.

For this, the engine variable FLOGO_APP_PROP_RECONFIGURE should be set to true for that particular app.

You can test these features with FLOGO_APP_PROP_SNAPSHOTS engine variable. When you dynamically override the app properties while the flow is running, it takes the values from the snapshot if this variable is set to true.
