 ## Serve the application
 
 ```bash

 This command deploys a new variant to the Agenta platform. It processes the code in the specified folder, with `myapp.py` as the entrypoint. This command builds a Docker image and deploys a container based on it. As a result, the variant becomes accessible in the web UI, allowing for prediction generation and API calls. The variant is named as `myapp.default` in the UI.
