DevOps – Start It Up

Almost all the pieces are in place to start up your local development environment. The last piece is an PHP file.

Create a folder called public in the appone folder.

cd ~/Code/appone

mkdir public

Create an index.php file in that folder.

cd public

touch index.php

Add some quick test code the index.php file.

<?php echo 'Hello, World!' ?>

Start up your docker project.

cd ~/Code/appone

docker-compose up -d

It might take a couple minutes because it will have to download the images from Docker Hub. The next time will be a lot faster.

If everything went well, try visiting the website in your browser.

http://localhost

If you see the text “Hello, world!”, then congratulations! Your local development environment setup with Docker was a success.

Here’s everything together.

~/Code/appone/docker-compose.yaml

version: '3.8'
services:

    # Application
    phpapp:
        build:
            context: ./docker
            dockerfile: phpapp.dockerfile
        working_dir: /var/www
        volumes:
            - ./:/var/www

    # Web Server
    webserver:
        build:
            context: ./docker
            dockerfile: webserver.dockerfile
        working_dir: /var/www
        volumes:
            - ./:/var/www
        depends_on:
            - "phpapp"
        ports:
            - 80:80

  # Database
  database:
    image: mysql:8.0
    command: --default-authentication-plugin=mysql_native_password
    volumes:
      - "./docker/data/db/mysql:/var/lib/mysql"
    environment:
      MYSQL_DATABASE: ${DB_DATABASE}
      MYSQL_ROOT_PASSWORD: ${DB_PASSWORD}
      MYSQL_PASSWORD: ${DB_PASSWORD}
      MYSQL_USER: ${DB_USERNAME}
    ports:
      - 33061:3306

You should also have a .env file in the root of your project.

~/Code/appone/.env

DB_HOST=database
DB_PORT=3306
DB_DATABASE=laravel
DB_USERNAME=laravel-user
DB_PASSWORD=laravel-password
MAIL_HOST=mailhog
MAIL_PORT=1025

Make sure these files exist in the docker folder of your project (~/Code/appone/docker).
