Now we can create a docker image for our app, but we still can’t use it, since it depends on MySQL, which, as good practice commens, will reside in a different container. We need our dependencies (Flask and mysql-connector) to be installed and delivered with the image, so we need to create the aforementioned requirements.txt file: Flask What this does is simply as described in the file - base the image on a Python 3.6 image, expose port 5000 (for Flask), create a working directory to which requirements.txt and app.py will be copied, install the needed packages and run the app. # Run app.py when the container launches COPY app.py /app CMD python app.py # Use an official Python runtime as an image FROM python:3.6 # The EXPOSE instruction indicates the ports on which a container # will listen for connections # Since Flask apps listen to port 5000 by default, we expose it EXPOSE 5000 # Sets the working directory for following COPY and CMD instructions # Notice we haven’t created a directory by this name - this instruction # creates a directory with this name if it doesn’t exist WORKDIR /app # Install any needed packages specified in requirements.txt COPY requirements.txt /app RUN pip install -r requirements.txt

A Dockerfile contains a set of instructions describing our desired image and allow its automatic build.

We want to create a Docker image for our app, so we need to create a Dockerfile in the app directory. init.sql - an SQL script to initialize the database before the first time the app runs.app.py - contains the Flask app which connects to the database and exposes one REST API endpoint.We begin with the following project layout: dockerize/ If you don’t have them installed yet, install Docker and docker-compose.
