PHP - Quick-Start using Docker

This repository serves as php (laravel or symfony) quick-start using docker.

Prerequisites

• Shell (Linux, MacOS, MS WSL2, VM)
• Docker

Quick-Start

• run hlp/init and follow the wizard

Other Helper Commands

• hlp/start - starts the project using docker-compose - http://localhost
• hlp/console "{command}" - show and run console (laravel or symfony) commands
• hlp/logs "{service}" - e.g. hlp/logs fpm
• hlp/status - show docker-composer services by status
• hlp/exec "{service}" "{command}" - run a command in a service e.g. hlp/exec fpm bash
• hlp/test "{filter}" - run phpunit tests e.g. hlp/test "ExampleTest::testSeomthing"
• hlp/build - build the docker image e.g. hlp/build "app/php-fpm:develop"
• hlp/restart - restart docker-compose
• hlp/stop - stop docker-compose
• hlp/composer - manage dependencies

Manage & Install Dependencies

Like all php projects, this one also manages dependencies with composer.

Install

You can review app/composer.json for the dependency versions and install them using the helper script:

hlp/composer install

For other dependency tasks (upgrade, add etc.) you can refer to the composer documentation

PHP Configuration

You can look and adjust the php configuration under config/php.ini and the fpm pool configuration under config/www.conf

Nginx Configuration

You can look and adjust the nginx configuration under nginx/nginx.conf and nginx/default.conf

Running Tests

As mentioned above, you can run tests using the helper hlp/test "{filter}". The filter has the following format if you want the highest specificity:

hlp/test "Namespace\\Path\\ClassName::testMethod"

Slash (/) and backslash () are converted to double backslash so you can also run:

hlp/test "Namespace/Path/ClassName::testMethod"
# or
hlp/test "Namespace\Path\ClassName::testMethod"

Alternatively you filter with lower specificity:

hlp/test "Path/ClassName"
# or
hlp/test "ClassName::testMethod"
# or
hlp/test "ClassName"

And if you want to work with phpunit directly you can use hlp/phpunit.

What I also like to do, when doing TDD or refactoring, is to use watch. I pick a test class and run the tests continuously while writing my code, so I continuously see the state of my test without having to run it manually everytime I change something.

watch --color "$(pwd)/test 'Example\ExampleTest'"

Debugging

Since this is a php project the debugger is, you guessed it, XDebug. It is installed but disabled by default in the docker image. To enable it we mount the configuration file (./xdebug/xdebug.ini) into the php-fpm services (fpm and test) in the docker-compose.yaml file.

To configure XDebug in PHPStorm follow these steps:

1. Add the server to File | Settings | Languages & Frameworks | PHP | Servers

The server name comes from the ./nginx/default.conf server_name

2. Add the "XDebug Helper" extension to chrome

3. Check debugging settings in phpstorm and start listening for connections

Dockerfile

The Dockerfile used for running php-fpm comes with a few preinstalled utilities like:

• Composer
• XDebug
• Imagick
• GD
• and many other ...

You are welcome to review the Dockerfile and adjust it to your needs
