Rasa Docker：无法连接到操作服务器，但它正在运行

如何解决Rasa Docker：无法连接到操作服务器，但它正在运行

我有一个完全在本地运行的 rasa 应用程序。之后，我使用 docker 构建并运行了应用服务器和活动服务器。 rasa 核心服务器运行良好，直到调用操作端点运行。行动。 我还在 endpoint.yml (http://127.0.0.1:5055/webhook) 中设置了操作端点 url 这是来自rasa核心服务器的日志：

这是来自服务器的日志

Dockerfile（运行rasa核心服务器）

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

Dockerfile（运行动作服务器）

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"

我哪里做错了？请帮帮我！

解决方法

您应该尝试一个 docker-compose 文件。您还应该确认操作服务器端口已通过 curl 公开并可用：

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