How to Set Up a Docker Container with PHP-Apache and Python

In the world of web development, integrating multiple languages within a single application can often present challenges, especially when it comes to containerization. A common use case is running a PHP web application alongside a Python script for specific functionalities.

Recently, a developer encountered issues while attempting to set up a Docker container that combines PHP-Apache and Python. Their local development environment worked perfectly, but trouble arose when they pushed their application to production. Let's dig into the solution they discovered and explore how to tackle this problem effectively.

The Problem

The developer's initial approach included a Dockerfile structured as follows:

However, this resulted in the error message: "sh: 1: python: not found". Furthermore, when the PHP-Apache section was removed, the container entered a continuous restart loop despite Python being installed.

The Solution: Two Separate Containers

After extensive research and troubleshooting, a viable solution emerged from community discussions: separating the environments into two distinct containers, one for PHP-Apache and the other for Python. Below is a breakdown of this approach:

Step 1: Creating the PHP-Apache Container

Base Image: Start with the official PHP-Apache image.

Extensions: Install any necessary PHP extensions, such as MySQLi and PDO.

Setup: Ensure your PHP application files are copied over.

Here is an example Dockerfile for the PHP-Apache container:

Step 2: Creating the Python Flask Container

Base Image: Use the official Python image that suits your application requirements (e.g., python:3.7).

Install Dependencies: Install required libraries by copying the requirements.txt file and using pip.

Build the Application: Implement a simple Flask API for handling requests.

Here's what the Dockerfile for the Flask application might look like:

Step 3: Enable Communication Between Containers

Creating two containers opens the opportunity for them to communicate. In this setup, the PHP container can send requests to the Python container using cURL.

cURL Example: Below is an example of how PHP can call the Flask API:

Make sure to update the docker-compose.yml file if you are using Docker Compose to link both services:

With services declared this way, Docker will handle the network connection between containers.

Conclusion

By utilizing separate containers for PHP-Apache and Python, developers can ensure their applications are more modular and easier to manage. Each container can now work independently, allowing for a clean separation of concerns while still achieving the desired functionality.



This method not only opens up possibilities for cleaner code but also simplifies debugging and testing, making it a recommended approach when working with multi-language applications in Docker.

Whether you're building a small project or a vast application, this guide should definitely set you on the road to successfully running PHP and Python together. Happy coding!
