Step 1 — Downloading Laravel and Installing Dependencies
cd ~ git clone https://github.com/laravel/laravel.git laravel-app - Next, use Docker’s composer image to mount the directories that you will need for your Laravel project and avoid the overhead of installing Composer globally:
docker run --rm -v $(pwd):/app composer install - As a final step, set permissions on the project directory so that it is owned by your non-root user:
sudo chown -R $USER:$USER ~/laravel-app Step 2 — Creating the Docker Compose File
vim ~/laravel-app/docker-compose.yml In the docker-compose file, you will define three services: app, webserver, and db. Add the following code to the file, being sure to replace the root password for MYSQL_ROOT_PASSWORD, defined as an environment variable under the db service, with a strong password of your choice:
~/laravel-app/docker-compose.yml version: '3' services: #PHP Service app: build: context: . dockerfile: Dockerfile image: digitalocean.com/php container_name: app restart: unless-stopped tty: true environment: SERVICE_NAME: app SERVICE_TAGS: dev working_dir: /var/www networks: - app-network #Nginx Service webserver: image: nginx:alpine container_name: webserver restart: unless-stopped tty: true ports: - "80:80" - "443:443" networks: - app-network #MySQL Service db: image: mysql:5.7.22 container_name: db restart: unless-stopped tty: true ports: - "3306:3306" environment: MYSQL_DATABASE: laravel MYSQL_ROOT_PASSWORD: your_mysql_root_password SERVICE_TAGS: dev SERVICE_NAME: mysql networks: - app-network #Docker Networks networks: app-network: driver: bridge - In the docker-compose file, define a volume called dbdata under the db service definition to persist the MySQL database:
~/laravel-app/docker-compose.yml . #MySQL Service db: . volumes: - dbdata:/var/lib/mysql networks: - app-network . ~/laravel-app/docker-compose.yml . #Volumes volumes: dbdata: driver: local - Next, add a bind mount to the db service for the MySQL configuration files you will create in Step 7:
~/laravel-app/docker-compose.yml . #MySQL Service db: . volumes: - dbdata:/var/lib/mysql - ./mysql/my.cnf:/etc/mysql/my.cnf . ~/laravel-app/docker-compose.yml #Nginx Service webserver: . volumes: - ./:/var/www - ./nginx/conf.d/:/etc/nginx/conf.d/ networks: - app-network - Finally, add the following bind mounts to the app service for the application code and configuration files:
~/laravel-app/docker-compose.yml #PHP Service app: . volumes: - ./:/var/www - ./php/local.ini:/usr/local/etc/php/conf.d/local.ini networks: - app-network Final docker-compose.yml file now look like this:
version: '3' services: #PHP Service app: build: context: . dockerfile: Dockerfile image: digitalocean.com/php container_name: app restart: unless-stopped tty: true environment: SERVICE_NAME: app SERVICE_TAGS: dev working_dir: /var/www volumes: - ./:/var/www - ./php/local.ini:/usr/local/etc/php/conf.d/local.ini networks: - app-network #Nginx Service webserver: image: nginx:alpine container_name: webserver restart: unless-stopped tty: true ports: - "80:80" - "443:443" volumes: - ./:/var/www - ./nginx/conf.d/:/etc/nginx/conf.d/ networks: - app-network #MySQL Service db: image: mysql:5.7.22 container_name: db restart: unless-stopped tty: true ports: - "3306:3306" environment: MYSQL_DATABASE: laravel MYSQL_ROOT_PASSWORD: your_mysql_root_password SERVICE_TAGS: dev SERVICE_NAME: mysql volumes: - dbdata:/var/lib/mysql/ - ./mysql/my.cnf:/etc/mysql/my.cnf networks: - app-network #Docker Networks networks: app-network: driver: bridge #Volumes volumes: dbdata: driver: local Step 4 — Creating the Dockerfile
FROM php:7.2-fpm # Copy composer.lock and composer.json COPY composer.lock composer.json /var/www/ # Set working directory WORKDIR /var/www # Install dependencies RUN apt-get update && apt-get install -y \ build-essential \ mysql-client \ libpng-dev \ libjpeg62-turbo-dev \ libfreetype6-dev \ locales \ zip \ jpegoptim optipng pngquant gifsicle \ vim \ unzip \ git \ curl # Clear cache RUN apt-get clean && rm -rf /var/lib/apt/lists/* # Install extensions RUN docker-php-ext-install pdo_mysql mbstring zip exif pcntl RUN docker-php-ext-configure gd --with-gd --with-freetype-dir=/usr/include/ --with-jpeg-dir=/usr/include/ --with-png-dir=/usr/include/ RUN docker-php-ext-install gd # Install composer RUN curl -sS https://getcomposer.org/installer | php -- --install-dir=/usr/local/bin --filename=composer # Add user for laravel application RUN groupadd -g 1000 www RUN useradd -u 1000 -ms /bin/bash -g www www # Copy existing application directory contents COPY . /var/www # Copy existing application directory permissions COPY --chown=www:www . /var/www # Change current user to www USER www # Expose port 9000 and start php-fpm server EXPOSE 9000 CMD ["php-fpm"] vim ~/laravel-app/php/local.ini upload_max_filesize=40M post_max_size=40M mkdir -p ~/laravel-app/nginx/conf.d vim ~/laravel-app/nginx/conf.d/app.conf . Add the following code to the file to specify your Nginx configuration:
Step 7 — Configuring MySQL
[mysqld] general_log = 1 general_log_file = /var/lib/mysql/general.log Step 8 — Running the Containers and Modifying Environment Settings
Now that you have defined all of your services in your docker-compose file and created the configuration files for these services, you can start the containers. As a final step, though, we will make a copy of the .env.example file that Laravel includes by default and name the copy .env, which is the file Laravel expects to define its environment:
With all of your services defined in your docker-compose file, you just need to issue a single command to start all of the containers, create the volumes, and set up and connect the networks:
Once the process is complete, use the following command to list all of the running containers:
Open the file using docker-compose exec, which allows you to run specific commands in containers. In this case, you are opening the file for editing:
docker-compose exec app vim .env Find the block that specifies DB_CONNECTION and update it to reflect the specifics of your setup. You will modify the following fields:
- DB_HOST will be your db database container.
- DB_DATABASE will be the laravel database.
- DB_USERNAME will be the username you will use for your database. In this case, we will use laraveluser.
- DB_PASSWORD will be the secure password you would like to use for this user account
DB_CONNECTION=mysql DB_HOST=db DB_PORT=3306 DB_DATABASE=laravel DB_USERNAME=laraveluser DB_PASSWORD=your_laravel_db_password docker-compose exec app php artisan key:generate docker-compose exec app php artisan config:cache Step 9 — Creating a User for MySQL
docker-compose exec db bash GRANT ALL ON laravel.* TO 'laraveluser'@'%' IDENTIFIED BY 'your_laravel_db_password'; FLUSH PRIVILEGES; exit exit Step 10 — Migrating Data and Working with the Tinker Console
docker-compose exec app php artisan migrate Once the migration is complete, you can run a query to check if you are properly connected to the database using the tinker command:
docker-compose exec app php artisan tinker \DB::table('migrations')->get(); About
