Question

我已经创建

Dockerfile
app.py
requirements.txt

这里是我的代码

app.py

import os
from flask import Flask
app = Flask(__name__)

@app.route("/")
def main():
    return "Welcome!"

@app.route('/how are you')
def hello():
    return 'I am good, how about you?'

if __name__ == "__main__":
    app.run(debug=True, host="0.0.0.0", port=8080)

requirements.txt

 Flask

Dockerfile

 FROM ubuntu:latest
 RUN apt-get update -y
 RUN apt-get install -y python-pip python-dev build-essential
 COPY . /app
 WORKDIR /app
 RUN pip install -r requirements.txt
 ENTRYPOINT ["python"]
 CMD ["app.py"]

然后我制作图像

docker build . -t dede-flask:latest

但是我在运行脚本时遇到了错误

首先我尝试使用此代码

  docker run dede-flask:latest

我出错了

    raise child_exception

我也尝试使用此代码

docker run -d -p 5000:5000 dede-flask:latest

我遇到错误

docker: Error response from daemon: driver failed programming external connectivity on endpoint friendly_bhaskara (990535df1272811a3991c8a11e06476267e027484b850c244ca195e9d5b8a220): Error starting userland proxy: mkdir /port/tcp:0.0.0.0:5000:tcp:172.17.0.2:5000: input/output error.

将Docker与Windows的Dockerize ubuntu
