Set Environment Variables

Most deployment-level settings in TestGen — SMTP credentials, single sign-on, custom branding, and MCP options — are applied through environment variables. The steps to set a variable depend on the install mode. After setting any variable, restart the application for the change to take effect.

Docker mode

1. Navigate to the directory that contains the docker-compose.yml file for TestGen.

   • If the instance was installed using dk-installer.exe, the file can be located under "AppData\Local\DataKitchenApps".
   • If the instance was installed using dk-installer, the file can be located in the folder from which the Python installer was executed.

2. Add each variable under the x-common-variables section, one variable per line.

   x-common-variables: &common-variables
    TG_EXAMPLE_VARIABLE: <value>
   

3. Restart the application.

   docker compose up -d --wait
   

Pip mode

1. Open the ~/.testgen/config.env file in a text editor.

2. Add each variable on its own line, no quotes.

   TG_EXAMPLE_VARIABLE=<value>
   

3. Restart the application. Stop the running TestGen process with Ctrl+C in the terminal where it is running, then start it again.

   python3 dk-installer.py tg start
