docker - docker-compose端口未公开

Question

当我尝试从外部访问lambda端点时，出现此错误:

curl -XPOST 127.0.0.1:3000/create-loan

Recv failure: Connection reset by peer

但是在docker内部，端点可以正常工作，端口3000不能从外部运行。
有什么帮助吗？

volumes:

我的DockerFile :

FROM python:3.7

RUN pip3 install aws-sam-cli

EXPOSE 3000

ENTRYPOINT ["/usr/local/bin/sam"]

RUN apt-get install curl

RUN pip3 install pipenv

WORKDIR /app
RUN pipenv install --dev
CMD ["local", "start-api"]

解决了

CMD ["local","start-api","--host","0.0.0.0"]

通过撰写文件，您已经暴露了端口3001

ports:
  - "3001:3000"

但是连接到3000

curl -XPOST 127.0.0.1:3000/create-loan
