Hi,

The old docker file is not working getting error -> I have updated the docker file (Thank You for your docker course)

FROM ubuntu
RUN apt-get update && apt-get install -y python3 python3-pip
RUN pip install Flask
COPY app.py /opt/
ENTRYPOINT FLASK_APP=/opt/app.py flask run --host=0.0.0.0 --port=8080

This is what made it work for me today. I also needed to map top port 5000 on the backend but not sure why.

FROM ubuntu

RUN apt-get update
RUN apt-get install -y python2 python-pip

RUN pip2 install flask

COPY app.py /opt/app.py

ENTRYPOINT FLASK_APP=/opt/app.py flask run --host=0.0.0.0

My app.py file looks like this

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(host="0.0.0.0", port=8080)
