Developing and testing a Laravel project requires to install a substantial number of tools, with the correct version of each: PHP, composer, MySQL database, NPM etc. Moreover, for a substantial project, you will also have to run and test a queue worker and a scheduler. This can become quite complex and long to setup. In this blog post we show how to use docker-compose to run all of these in a single command line...
Updated May 2022: the
cylab/laravel-dev image now uses docker-compose-wait to wait for MySQL to be up...
There is only one prerequisite for this setup: you must have Docker and docker-compose correctly installed. So you can even start developing and testing your Laravel project without installing PHP...
The main point to run a Laravel development environment is to create the appropriate docker-compose.yaml file, like in the example below:
# # docker-compose.yaml # https://cylab.be/blog/190/run-a-development-environment-for-laravel-with-docker-compose # # This docker-compose can be used to run a complete development environment for Laravel projects # version: "3" services: web: image: cylab/laravel-dev depends_on: - redis - mysql ports: - 8080:80 volumes: - .:/var/www/html env_file: .env environment: WAIT_HOSTS: mysql:3306 queue: image: cylab/laravel-dev depends_on: - web volumes: - .:/var/www/html command: ["php", "artisan", "queue:work", "--verbose", "--tries=3", "--timeout=60"] restart: unless-stopped env_file: .env environment: WAIT_HOSTS: web:80 scheduler: image: cylab/laravel-dev depends_on: - cyrange volumes: - .:/var/www/html command: ["/scheduler.sh"] env_file: .env environment: WAIT_HOSTS: web:80 node: image: node:10-alpine working_dir: /app volumes: - .:/app entrypoint: /bin/sh -c "npm install && npm run watch-poll" depends_on: - web redis: image: redis:4-alpine volumes: - ./volumes/redis:/data mysql: image: mysql:5.7 volumes: - ./volumes/mysql:/var/lib/mysql environment: MYSQL_ROOT_PASSWORD: root MYSQL_DATABASE: laravel
This docker-compose runs 6 containers:
The main point is that we use a custom Docker image cylab/laraveldev to run our application. This image has been configured specifically to run Laravel applications. Moreover, when the container starts, it will download composer dependencies, and run database migrations...
The docker-compose description also instructs the 3 laravel-dev containers to use a custom env file called env.dev, like the one below:
# # env.dev # https://cylab.be/blog/190/run-a-development-environment-for-laravel-with-docker-compose # # Environment file used to run a development environment with docker-compose # # APP_NAME=Laravel APP_ENV=dev APP_KEY=base64:ezEe4jH/6EUM2fMWLnco3kuMz1OMStq/XfV456ZwMhc= APP_DEBUG=true APP_URL=http://localhost:8080 LOG_CHANNEL=stack DB_CONNECTION=mysql DB_HOST=mysql DB_PORT=3306 DB_DATABASE=laravel DB_USERNAME=root DB_PASSWORD=root BROADCAST_DRIVER=log CACHE_DRIVER=redis QUEUE_CONNECTION=redis SESSION_DRIVER=redis SESSION_LIFETIME=120 REDIS_HOST=redis REDIS_PASSWORD=null REDIS_PORT=6379 MAIL_DRIVER=log #MAIL_DRIVER=smtp #MAIL_HOST=smtp.mailtrap.io #MAIL_PORT=2525 #MAIL_USERNAME=null #MAIL_PASSWORD=null #MAIL_ENCRYPTION=null
You can start your containers with the usual docker-compose command:
After a few seconds, your Laravel application will be available at
In the background, there is actually a lot that will take place:
Your PHP code is exported as a volume inside the
web container (like a shared folder). Hence each time you modify your code on the host machine, the result is immediately visible in your browser (after a refresh of the page)...
You can also use the
web container to run your tests:
docker-compose exec -u www-data web vendor/bin/phpunit --coverage-text
Remark: after running the test, you may have to recreate the DB structure with artisan:
docker-compose exec -u www-data web php artisan migrate:fresh
If you need additional composer packages, the composer command must be executed inside the
docker-compose exec web composer require <package>
node container constantly watches your CSS and JS code for modifications. Each time you modify your CSS or JS code on the host machine, the
node container will immediately recompile the new assets. Hence the new version is also immediately visible in your browser (after a refresh of the page)...
If you need to install additional npm packages, the npm command must be executed inside the
docker-compose exec node npm install <package>
If your project uses queues, the jobs will be executed by a separate
queue container. This container is a long lived process. Hence the modifications to PHP code will only be 'visible' after restarting the process:
docker-compose restart queue
All the data created by the MySQL and redis containers will be stored in local volumes, under the
volumes directory. This directory should not be commited to your GIT server. Hence you should add the following to your .gitignore:
