Setting Component Environment Variables

Environment variables are set in the container running environment and can be modified after component deployment, ensuring the flexibility of applications.

Environment variables set for an application component are local environment variables and take effect only for this application component.

If you add an application environment variable to the application where the component is located and the name of the application environment variable is the same as that of the component environment variable in the application, the application environment variable is shielded by the component environment variable and does not take effect for the component. For details about how to add application environment variables, see Managing Application Environment Variables.

This topic describes how to configure component environment variables in different deployment modes during component deployment. For details about the component deployment mode, see Deploying a Component.
