Can't run custom action with Docker

Rasa Open Source
1

Hey i’m trying to create a chatbot with RASA in Docker but i can’t use custom action, the bot don’t respond.

I’m running the action server in a Docker container with docker-compose. This is the docker-compose.yml file :

version: '3.0'
services:
  action_server:
    image: rasa/rasa-sdk:latest
    volumes:
      - ./actions:/app/actions

And this is my endpoints.yml file :

action_endpoint:
  url: "http://action_server:5055/webhook"

To interact with the chatbot, i execute rasa/rasa:latest image Docker with this command :

docker run -it --network="chatbot_rasa_default" -v $(pwd):/app rasa/rasa interactive

But at the moment where the bot should execute the custom action, he said nothing (it’s the same thing when i use rasa shell -vv cmd):

? Your input -> hey
? Your NLU model classified 'hey' with intent 'greet' and there are no entities, is this correct?  Yes

? The bot wants to run 'action_hello_world', correct?  Yes

                                   intent: greet 0.80

 3    action_hello_world 1.00
------
? The bot wants to run 'action_listen', correct?  (Y/n)

The bot sould respond “Hello World !” because it is written in action/action.py file :

from typing import Any, Text, Dict, List
from rasa_sdk import Action, Tracker
from rasa_sdk.executor import CollectingDispatcher
class ActionHelloWorld(Action):
    def name(self):
        return "action_hello_world"
    def run(self, dispatcher, tracker, domain):
        print("Hello")
        print("this is tracker",tracker)
        dispatcher.utter_message("Hello World!")
        return []

But i noticed that the action server logs returned nothing :

[root@vm]# docker-compose up
Creating network "chatbot_rasa_default" with the default driver
Creating chatbot_rasa_action_server_1 ... done
Attaching to chatbot_rasa_action_server_1
action_server_1  | 2019-11-15 10:19:17 INFO     rasa_sdk.endpoint  - Starting action endpoint server...
action_server_1  | 2019-11-15 10:19:17 INFO     rasa_sdk.executor  - Registered function for 'action_hello_world'.
action_server_1  | 2019-11-15 10:19:17 INFO     rasa_sdk.endpoint  - Action endpoint is up and running on http ('0.0.0.0', 5055)

Why the bot didn’t respond “hello world !” ? I missed a step ?

Hello @vivitare,

Are you running the Rasa server and the action server separately, not in the same Docker network ? I don’t see the Rasa server service in your docker-compose.yml

Thks @fuih

Nope, they can communicate with each other because i run rasa with this command :

docker run -it --network="chatbot_rasa_default" -v $(pwd):/app rasa/rasa:latest shell -vv

When he can’t communicate with the action server, a message appear that they can’t communicate with each other.

4

Are you running it in two separate docker containers or the way it is described in Running Rasa with Docker? If they are separate I think you might need to open the port for the action server

5

they don’t need open port because they are in the same network, they can ping between them.

Hola @vivitare!

Shooting from the hip here a little, but I think I had the same problem. Try making the docker --network in your docker container the same as the action_endpoint in endpoints.yml.

So the final command would look something like this:

docker run -it --network="action_server" -v $(pwd):/app rasa/rasa:latest shell -vv

Hope that helps!

@vivitare I had the same problem. You were able to solve it ?
