Application Environment Variable Overview

Environment variables are parameters set in the system or user applications. You can obtain the values of environment variables by calling APIs. During deployment, parameters are specified through environment variables instead of in the code, which makes the deployment flexible. Environment variables added to an application are global environment variables and take effect for all application components.

To add environment variables for a specific component:

• For container-deployed components, see Configuring Environment Variables of a Component.
• For VM-deployed components, see Adding a Component Environment Variable.
