I don’t know if the problem is still actual, but maybe this will help someone looking for the answer.
You need to add actions service to your docker-compose.yml file:
version: '3.0'
services:
rasa:
image: rasa/rasa:latest
restart: always
ports:
- 5005
volumes:
- ./app:/app
command:
- run
actions:
image: rasa/rasa-sdk:latest
restart: always
volumes:
- ./app/actions:/app/actions
ports:
- 5055
This way when you run docker compose up you gonna have two docker containers: one with rasa assistant and one with actions server.
