Being a Software Engineer isn't just about being effective in a specific programming language, it's about being able to solve any given problem using the tools at hand.
This week at work I have to extend the functionality of a WordPress plug-in so it can fit into our microservices-based backend architecture. This means learning enough PHP to write some production-grade code.
I don't want to install PHP on my local machine so this is the perfect use case for Docker! In this Quick Hit, I will describe how to create a containerized PHP + MySQL development environment using Docker Compose.
The LAMP Stack is back!
We'll start by creating a folder for this project:
mkdir lamp-stack && cd lamp-stack
Create another subdirectory,
/phpwhich contains the following
<!-- ./php/index.php --> <html> <head> <title>Hello World</title> </head> <body> <?php echo "Hello, World!"; ?> </body> </html>
docker-compose.ymlwith the following configuration:
# ./docker-compose.yml version: '3' services: db: image: mysql:5.7 environment: MYSQL_ROOT_PASSWORD: my_secret_pw_shh MYSQL_DATABASE: test_db MYSQL_USER: devuser MYSQL_PASSWORD: devpass ports: - "9906:3306" web: image: php:7.2.2-apache container_name: php_web depends_on: - db volumes: - ./php/:/var/www/html/ ports: - "8100:80" stdin_open: true tty: true
- Our directory structure should look as follows:
$ tree . ├── docker-compose.yml └── php └── index.php
docker-compose up -din the terminal and load http://localhost:8100/ in your browser.
- We use port-forwarding to connect to the inside of containers from our local machine.
- Our local directory,
./php, is mounted inside of the webserver container as
- The files within in our local folder will be served when we access the website inside of the container
