Running a Rasa SDK Action Server

There are two ways to run the action server, depending on whether you are using an environment with rasa installed or not:

If rasa is installed, you can run the action server using a rasa command:

rasa run actions

Alternatively you can make your assistant listen on a specific address using the SANIC_HOST environment variable:

SANIC_HOST= rasa run actions

If rasa is not installed, you can run the action server directly as a python module:

python -m rasa_sdk --actions actions

Running the action server directly as a python module allows for SANIC_HOST too:

SANIC_HOST= python -m rasa_sdk --actions actions

Using the command above, rasa_sdk will expect to find your actions in a file called or in a package directory called actions. You can specify a different actions module or package with the --actions flag.

The full list of options for running the action server with either command is:
