php database dockerization

With the rapid development of cloud computing and containerization technology, more and more developers are beginning to Docker their applications to improve efficiency and convenience. Today, we will explore how to Dockerize the popular development language PHP and database to achieve a more efficient and portable development process.

1. What is Docker

First of all, let us briefly introduce Docker. Docker is a containerization technology that packages applications and services into a container to run in different environments. Unlike traditional virtual machines, Docker can start and stop containers more quickly, and provides a more lightweight environment and more efficient resource management.

Using Docker can make applications more portable and reproducible, because their running environment and dependencies can be packaged in containers and can be easily deployed and run in different environments .

2. Why Dockerize PHP and Database

For PHP developers, the benefits of Dockerization are obvious. First, PHP applications often rely on many libraries and extensions, and packaging them into Docker containers avoids the complexity and possible conflicts of installing these dependencies.

Secondly, since different PHP applications may need to connect to different databases, packaging the database and application in the same container will not only make the container heavier, but also less flexible. Packaging them in separate containers makes them more modular and reusable.

3. How to Docker PHP and database

Next, we will introduce how to Docker PHP applications and databases, and the integration between them.

  1. Dockerizing PHP applications

To Dockerize a PHP application, we first need to create a Dockerfile. A Dockerfile is a text file that defines the contents of a Docker image and contains the instructions and commands required to create the image.

The following is a basic Dockerfile example:

FROM php:7.4-apache
COPY src/ /var/www/html/
Copy after login

This Dockerfile uses an Apache-based PHP 7.4 image and copies the application code to the container's /var/www/html / directory.

To build this image, please run the following command in the directory where the Dockerfile is located:

docker build -t my-php-app .
Copy after login

If everything goes well, you will see the output of the build process, and finally build a file named Mirror of my-php-app.

  1. Dockerized database

Next, we need to Dockerize the database. Here we will use MySQL, a popular relational database, as an example.

To use the MySQL Docker image, we need to run the following command:

docker run -d --name my-mysql -e MYSQL_ROOT_PASSWORD=my-secret-pw mysql:5.7
Copy after login

This command will download the mysql:5.7 image and start MySQL in a container named my-mysql. It also sets the environment variable MYSQL_ROOT_PASSWORD to my-secret-pw via the -e option, which will be used as the password for MySQL’s root user.

  1. Integrating PHP Application and MySQL

Now, we need to write the PHP application code so that it can connect to the MySQL database.

The following is a sample code to connect to MySQL using the PHP PDO extension:

$pdo = new PDO('mysql:host=my-mysql;dbname=my-db', 'root', 'my-secret-pw');
Copy after login

Here, we use the PDO object to connect to the MySQL instance in the my-mysql container that was running before. You can replace my-mysql with the actual IP address or hostname from the MySQL container, and my-db is the name of the database we want to connect to.

If everything is set up correctly, the application will connect to the MySQL database and can use PDO to perform operations such as queries.

4. Summary

By Dockerizing PHP and database, we can achieve a more efficient and portable development process. Using Docker containers makes it easy to manage applications and their dependencies, and makes applications and databases more reusable and modular. By packaging them in different containers, we can manage the relationship between them more flexibly and achieve more efficient deployment and operation.
