Docker Compose is a powerful tool for defining and managing multi-container Docker applications. In this tutorial, we'll walk through setting up a simple Python application with a MySQL database using Docker Compose. This example will demonstrate how to create a Python application that connects to a MySQL database within separate Docker containers.
Before you begin, make sure you have the following installed on your system:
Create a new directory for your project and navigate into it. Inside the project directory, create the following files:
Open app.py in a text editor and add the following Python script. This script connects to a MySQL database and performs a simple query.
Open requirements.txt and add the following line to specify the pymysql dependency.
Open Dockerfile and define the Docker image for your Python application.
Open docker-compose.yml and define the services for your application and MySQL database.
In the project directory, run the following command to build and start the containers:
This command will download the necessary images, build the Python application image, and start both containers. You should see the output of the Python script, including the database query result.
To stop the containers, press Ctrl + C in the terminal where docker-compose up is running.
