Rasa Docker：無法連接到操作服務器，但它正在運行

Question

我有一個完全在本地運行的 rasa 應用程序。 之后，我使用 docker 構建並運行了應用服務器和活動服務器。 rasa 核心服務器工作正常，直到調用操作端點運行。 行動。 我還在 endpoint.yml 中設置了動作端點 url （ http://127.0.0.1:5055/webhook ）這是來自 rasa 核心服務器的日志：

2021-03-04 12:59:18 DEBUG rasa.core.actions.action - Calling action endpoint to run action 'action_form_search'.

2021-03-04 12:59:18 ERROR rasa.core.actions.action - Failed to run custom action 'action_form_search'. Couldn't connect to the server at 'http://127.0.0.1:5055/webhook'. Is the server running? Error: Cannot connect to host 127.0.0.1:5055 ssl:default [Connection refused]

2021-03-04 12:59:18 ERROR rasa.core.processor - Encountered an exception while running action 'action_form_search'.Bot will continue, but the actions events are lost. Please check the logs of your action server for more information.

Traceback (most recent call last):

The above exception was the direct cause of the following exception:

這是來自服務器的日志

Dockerfile（運行rasa核心服務器）

FROM rasa/rasa:2.3.2

COPY . /app

WORKDIR /app

EXPOSE 5005

COPY startup.sh /app/scripts/startup.sh

USER root
RUN pip install --no-cache rasa==2.3.2
RUN chmod a+x /app/scripts/startup.sh

WORKDIR /app

ENTRYPOINT ["bash"]

CMD ["scripts/startup.sh"]

Dockerfile（運行動作服務器）

FROM python:3.7.5-slim

RUN apt-get update -qq

COPY . /app/actions/
COPY ./startup.sh /app/startup.sh
ADD requirements.txt /app/requirements.txt

WORKDIR /app

EXPOSE 5055

STOPSIGNAL SIGINT

USER root
RUN python -m pip install --upgrade pip
RUN pip install -r requirements.txt --no-cache-dir

RUN chmod a+rx ./startup.sh
ENTRYPOINT "./startup.sh"

我在哪里 go 錯了？ 請幫我！

Answer 1

您應該嘗試一個docker-compose文件。 您還應該確認操作服務器端口已通過 curl 公開並可用：

curl --request POST 'http://localhost:5055/webhook'
