Gust Roles

You can run Gust with different runtime roles by setting GUST_ROLE:

• core: runs the DAG pool and execution workers without the web UI.

  GUST_ROLE=core iex --sname core -S mix run --no-halt
  

• web: runs the Phoenix server and loads DAG definitions for the UI, but does not execute DAGs.

  GUST_ROLE=web iex --sname web -S mix phx.server
  

• console: loads DAG definitions and supporting runtime pieces for CLI or IEx work, but does not start DAG pooling workers.

  GUST_ROLE=console iex -S mix
  

mix gust.cli ... also defaults GUST_ROLE to console, and release builds ship a gust-cli wrapper that exports the same role automatically.

If you do not pass anything, Gust runs as single, which enables both the core and web behavior in the same node.

For choosing how core nodes pick up ready runs across a multi-node setup, see Run Dispatcher in the Configuration guide.
