Hello… I have set up RasaX in a cluster environment using Kubernetes. I am however failing to connect to the duckling server. I am getting the error on the rasa production container. : 2020-03-02 03:37:57 ERROR rasa.nlu.extractors.duckling_http_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: GitHub - facebook/duckling: Language, engine, and tooling for expressing, testing, and evaluating composable language rules on input strings.

I am thinking that duckling is using another hostname that is not “duckling” that is why I am getting this error. What should i put in my config file to fix this

Hey @SimbaM , so the url won’t just be duckling, it’ll be the service name. So probably something similar to <release-name>-duckling, but you can check that in your kubernetes console

Hi @SimbaM , Did you use the Rasa X helm charts to deploy rasa x to your kubernetes cluster?

Yes… I basically followed through the steps in the Master class

Hey @akelad Thanks for your response. So I did as you advised, but still cant connect to duckling. So these are the steps that I took: Getting the name of the service kubectl get services --namespace=rasaxkube NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE rasa-x-1583082199-app ClusterIP 10.12.8.92 5055/TCP,80/TCP 6d1h rasa-x-1583082199-duckling ClusterIP 10.12.13.245 8000/TCP 6d1h Insert it in the config file: language: en pipeline: name: SpacyNLP name: SpacyTokenizer name: SpacyFeaturizer name: RegexFeaturizer name: CRFEntityExtractor name: EntitySynonymMapper name: SklearnIntentClassifier name: DucklingHTTPExtractor url: ‘ http://rasa-x-1583082199-duckling ’ dimensions: time number amount-of-money policies: name: MemoizationPolicy name: KerasPolicy name: MappingPolicy name: FormPolicy name: FallbackPolicy nlu_threshold: 0.4 core_threshold: 0.3 fallback_action_name: action_sos Had a sample chat and this was what was in the logs of the production pod. 2020-03-08 12:23:42 ERROR rasa.nlu.extractors.duckling_http_extractor - Failed to connect to duckling http server.
