Run Dayu System
Start the support layer
Run the script from the repository root:
TEMPLATE=template ACTION=start bash dayu.sh
The command starts Backend, Frontend, Datasource, and Redis. It does not install the selected scheduler policy or application DAG. Open the Frontend URL printed by the script, then complete the application installation workflow.
To stop Dayu:
TEMPLATE=template ACTION=stop bash dayu.sh
The stop command first asks Backend to stop the active query and application runtime, then completes support-layer
cleanup. Runtime uninstall is asynchronous: the frontend and GET /install_state may show cancellation, uninstall, or
finalization phases while exact RuntimeService-owned objects are being removed.
Operate in the frontend
Open the home page
Orchestrate the task DAG
Configure the source
Install the application runtime
Choose a policy, datasource, DAG, and allowed nodes. The page remains in progress until Backend commits an active RuntimeDirectory. If installation is cancelled or fails after resources were created, use the same page to complete cleanup before starting another installation.
