Unable to run Duckling server using docker-compose

Rasa Open Source

@jpark2111 go with the generic approach please don’t mention dockerignore and copy everything which is required for model training.

22

@nik202 If I’m not using dockerignore file and copying everything, COPY . /app this line should be removed tho, correct? Even then all the config, credential, domain and endpoint.yml files are copied manually one by one to docker container? I’m confused here :frowning:

23

@jpark2111 no no you can even copy a single file too but as per training, we required some files.

@jpark2111 can you inspect the container? when you copied all file?

docker exec -u root -t -i <container ID> /bin/bash

You need to inspect

@nik202 Action server now is working, again I need to allow the 5055 port on VM. But duckling still getting error, port 8000 also is being allowed. attaching error message and files you might want to look at.

 rasa.nlu.extractors.duckling_entity_extractor  - Failed to connect to duckling http server. Make sure the duckling server is running/healthy/not stale and the proper host and port are set in the configuration. More information on how to run the server can be found on github: https://github.com/facebook/duckling#quickstart Error: HTTPConnectionPool(host='localhost', port=8000): Max retries exceeded with url: /parse (Caused by NewConnectionError('<urllib3.connection.HTTPConnection object at 0x7ffadb98b640>: Failed to establish a new connection: [Errno 111] Connection refused'))

This is duckling config in config.yml

  - name: DucklingEntityExtractor
    url: http://duckling:8000

Is this is the right image?

26

I changed it to latest, still getting same error. Do I need to train model again? Since I’m using a model that trained during docker image is being built, do I need to build docker image for rasa again? @nik202

27

@jpark2111 yes, delete all the images and volume and run docker-compose build . do let me know.

@jpark2111 do check the duckling command which you mentioned in docker-compose.yml

CMD ["duckling-example-exe", "-p", "8000", "--no-access-log", "--no-error-log"]

28

@nik202 rasa server, action server and duckling are all up and running without issue now :slight_smile: Thank you for your support!!

29

@jpark2111 Great! :+1::+1: Next time please create a new thread for the new issue. Have a great day!

@jpark2111 for a record and feedback do share the final files (docker and docker-compose) for other readers whenever you got time.

Hi @nik202 ,

I have recently started to develop a chatbot using rasa and currently I am trying to talk to a bot using docker compose. I have set up a docker compose file, a docker file in the main folder and a docker file in the action folder. I have made sure that the action-server defined in the docker compose is same in the endpoints.yml file and followed the solution at- Unable to run Duckling server using docker-compose - Rasa Open Source - Rasa Community Forum.

When I run the docker compose file, the duckling, rasa server and action server starts but when I try to talk to the bot, the first error is “Failed to connect to duckling server” and also all the “action session” fails to start.

docker-compose.yml (772 Bytes) Dockerfile (255 Bytes) Dockerfile_Action (214 Bytes)

Error on starting shell is: ‘’’ ERROR rasa.core.actions.action - Failed to run custom action ‘action_session_start’. Couldn’t connect to the server at ‘http://action-server:5056/webhook’.

Please check the logs of your action server for more information. ‘’’

I am using Rasa version 2.2.9

Please give suggestions to enable my bot and let me know if any further information is required.

Thank you
