PHP and Mysql environment with Docker

Create a Dockerfile in your PHP project

FROM php:8.2-cli

COPY . /usr/src/myapp

WORKDIR /usr/src/myapp

CMD [ "php", "./your-script.php" ]

Then, run the commands to build and run the Docker image:

$ docker build -t my-php-app .

$ docker run -it --rm --name my-running-app my-php-app

Run a single PHP script For many simple, single file projects, you may find it inconvenient to write a complete Dockerfile. In such cases, you can run a PHP script by using the PHP Docker image directly:

Create a Dockerfile with the code below:


FROM php:8.2-cli
COPY example_app/ /var/www/html
COPY --from=composer:latest /usr/bin/composer /usr/local/bin/composer
EXPOSE 80


Create a docker-compose.yml file with code below

version: "3.7"
services:
  web:
    build: .
    volumes:
      - ./example_app:/var/www/html
    ports:
      - "80:80"
  db:
    image: mysql
    volumes:
      - ./db-data:/var/lib/mysql
    environment:
      MYSQL_ROOT_PASSWORD: root
      MYSQL_DATABASE: example_app
    ports:
      - "3306:3306"
