无法从Docker外部访问在Docker中运行的Flask Service [英] Not able to access Flask Service running in docker from outside the docker
问题描述
我已经在docker内部创建了一个flask服务
I have created a flask service inside docker
import json
from flask import Flask, request
app = Flask(__name__)
@app.route("/", methods=["GET", "POST"])
def home():
return "App is working"
if __name__ == "__main__":
app.run("0.0.0.0", debug=False)
但是我无法从Docker外部访问以上服务.
But I am not able to access above service from outside the docker.
我的 Dockerfile 是
FROM python:3.7
MAINTAINER sociopath(xyz@gmail.com)
COPY requirements.txt domain.yml config.yml /tmp/
COPY data /tmp/data
COPY helper /tmp/helper
COPY models /tmp/models
COPY app.py /tmp/app.py
WORKDIR /tmp
RUN pip install -r requirements.txt
EXPOSE 5000
CMD flask run --host 0.0.0.0
我使用命令构建它
docker build.-t cont1
并使用
docker run -d -p 5000:5000 --name c1 cont1
当我从docker内部发送请求时，我得到 App正在运行，但是当我尝试从我的计算机访问时没有响应.
When I send the request from inside the docker I get App is working but no response when I try to access from my machine.
修改
我有Windows操作系统，正在使用安装了docker的Ubuntu VM.我在Ubuntu上收到响应，但是当我尝试从Windows访问同一文件时，我收到了错误消息.
I have windows OS in which I'm using Ubuntu VM where docker is installed. I get response on Ubuntu but When I try to access the same from windows I received an error.
推荐答案
Expose your docker file to an external source(Listener)(Ref)
EXPOSE 5000
例如:-
FROM python:3.7
MAINTAINER sociopath(xyz@gmail.com)
COPY requirements.txt domain.yml config.yml /tmp/
COPY data /tmp/data
COPY helper /tmp/helper
COPY models /tmp/models
COPY app.py /tmp/app.py
WORKDIR /tmp
RUN pip install -r requirements.txt
EXPOSE 5000
CMD flask run --host=0.0.0.0
