php-laravelHow do I use Docker Compose to deploy a Laravel application in PHP?

To deploy a Laravel application in PHP using Docker Compose, follow these steps:

1. Create a docker-compose.yml file in the root of your Laravel application.

version: '3'
services:
  web:
    build: .
    ports:
      - "80:80"
    volumes:
      - ./:/var/www/html
    links:
      - mysql
  mysql:
    image: mysql:5.7
    environment:
      MYSQL_ROOT_PASSWORD: secret
      MYSQL_DATABASE: laravel

2. Run the docker-compose up -d command to start the containers in detached mode.

$ docker-compose up -d

3. Install the dependencies for the application with docker-compose exec web composer install.
