PHP+nginx+PostgreSQL+pgAdmin on Docker in 2019

This code is a template for a PHP website (Laravel served via nginx and php-fpm) along with its database (PostgreSQL+pgAdmin).

It just works: . Clone and get started.

Why? Because this has been surprisingly time-consuming to setup (see the "pain points" below), and it really shouldn't be.

What's in the box

• Minimal website with Laravel, served via nginx and php-fpm, all wired up through docker-compose
• PostgreSQL+pgAdmin
• Source code + DB files mapped to host through Docker volumes
• Simplified dev cycle through Makefile commands (make serve, serve-dev, test-unit, test-integration, etc)
• Composer to manage PHP libraries
• Working CI setup with Travis for unit tests, plus...
• Dusk/Selenium for integration-tests, which runs on Travis and uploads failing screenshots to imgur
• Working XDEBUG setup for VS Studio Code/PHPStorm (so you can debug with breakpoints)

How to use

• Clone this repo
• make serve to build and serve
• make composer-update on the first run
• make test to run unit and integration tests

Pain points solved

• No turnkey setup available: either partial* solutions**, or many blog posts which I had to painfully combine to get this setup
• PostgreSQL creates files as root, which conflicts with docker build (solution: appropriate .dockerbuild). Similar problem for artisan (solution: appropriate alias)
• Running composer install in the Dockerfile was shadowed by the volume mapping the source to the host (solution: separate command in Makefile, required once only)
• Simultaneously running make serve and make test on Travis (solution: script to busy-wait on container)
• Getting Dusk/Selenium's output on failures on Travis (solution: a script to copy to stdout and upload screenshots to imgur)
• Getting the PHP container to connect to XDEBUG on host (solution: a hack to fix host.docker.internal on Linux)

*(lacks CI) **(lacks DB)

Remarks

• Host should run VSCode (XDEBUG config is given), have PHP set for linting

• Laravel uses artisan to build things. This should be called inside the docker

• Website runs on port 8080

• PGAgmin runs on port 8081

• PHP-Fpm runs on port 9000

• XDebug should run on 9001 on host (to be run in VSCode, and started before loading the page)

• website/data/storage should allow "others" to write

• php artisan key:generate regenerates secret keys for app-level crypto

• php artisan config:cache flushes and rebuilds the config cache

// Magic php cache rebuid thing composer dump-autoload

// Create a model with migration

// Rebuild db php artisan migrate:refresh (eventuellement --seed)

// Create a seed php artisan make:seeder SectionsTableSeeder

// Create a test in the Feature directory... php artisan make:test UserTest

// Create a test in the Unit directory... php artisan make:test UserTest --unit
