Trying to deploy a flask app using docker

Question

I am trying to deploy my python flask code to my Linux server and I am following the instruction provided in this link and I modified the required files as my project has app.py and static and templates folders. requirements.txt is already present. here are the contents of modified files:

uwsgi.ini

[uwsgi]
module = app
callable = app
master = true

Dockerfile is same

start.sh

#!/bin/bash
app="docker.test"
docker build -t ${app} .
docker run -d -p 56733:80 \
  --name=${app} \
  -v $PWD:/app ${app}

and when I open the webpage it does not load properly and images and css code are missing. I deployed it to heroku and everything works perfectly fine. Can you please help me where am I making a mistake?

Edit: Docker File:

FROM tiangolo/uwsgi-nginx-flask:python3.6-alpine3.7
RUN apk --update add bash nano
ENV STATIC_URL /static
ENV STATIC_PATH /var/www/app/static
COPY ./requirements.txt /var/www/requirements.txt
RUN pip install -r /var/www/requirements.txt

File structure of my project

Answer 1

The volume mapping in start.sh seems wrong, the source folder should be mapped to /var/www/ like this

-v $PWD:/var/www/ ${app}

Also your static folder is at the root of your project, in the example it's in an app folder, so either move it to an app folder or fix the ENV instruction like this :

ENV STATIC_PATH /var/www/app/static
