The story that docker had a hard time
This teaching material
Learn Test Driven Development with Laravel!
Get hooked on the swamp with Laravel's Migrate before tackling the challenge
Reset
Uninstall docker desktop
Start-> Settings-> App (usually disappears)
When I try to turn it off normally with explorer, a blue screen appears and it restarts, and I can't turn it off forever (I've never seen a blue screen in this era ...). It seems that there is no choice but to snap it off in powershell administrator mode
learning-laravel-Based on a directory called tdd
PS C:\WINDOWS\system32> cd D:\OneDrive\dev
PS D:\OneDrive\dev> rm -Force learning-laravel-tdd
Install Docker Desktop for Windows
https://hub.docker.com/editions/community/docker-ce-desktop-windows/ The installation itself goes smoothly
Clone git repository for Docker
OneDrive\dev>
$ mkdir learning-laravel-tdd
$ cd learning-laravel-tdd
$ git clone https://github.com/nunulk/learning-laravel-tdd-docker docker
$ mkdir app
Current state
learning-laravel-tdd
├── app
└── docker
Do it after starting Docker
$ cd docker
$ cp .env.example .env
$ docker-compose up -d
Resolve Port fog (DB_PORT to 3308)
In my case, I found that 3306 was on (because I usually use it in python)
learning-laravel-tdd\docker\.env
COMPOSE_PROJECT_NAME=learning-laravel-tdd
APP_PATH=../app
TZ=Asia/Tokyo
WEB_PORT=80
- DB_PORT=3306
+ DB_PORT=3308
DB_DATABASE=learning_laravel_tdd
DB_USERNAME=root
DB_PASSWORD=root
DB_TESTING_DATABASE=learning_laravel_tdd_testing
DB_TESTING_PORT=3307
DB_TESTING_USERNAME=root
DB_TESTING_PASSWORD=root
Then, when you start with Docker's control panel, everything will be turned on
Operation check
Execute the following command to check if all containers are running
learning-laravel-tdd\docker>
$ docker-compose ps

Creating a Models directory and moving User.php
By default, Laravel will generate the Model class directly under the app directory when you generate it with the artisan command, but in this teaching material, we will create a Models directory and place it there. Move User.php, which is automatically created by the installation, to the Models directory in advance.
First, execute the following command to create a directory (either the container side or the host side is fine).
learning-laravel-tdd\app
# mkdir app/Models
Then move app/User.php under app/Models and change the namespace.
learning-laravel-tdd\app\Models\User.php
namespace App\Models;
Also change the namespace of the part that refers to the User class.
The following two files are to be changed.
learning-laravel-tdd\app\config\auth.php
'providers' => [
'users' => [
'driver' => 'eloquent',
- 'model' => App\User::class,
+ 'model' => App\Models\User::class,
],
learning-laravel-tdd\app\database\factories\UserFactory.php
- use App\User;
+ use App\Models\User;
config is ignored
Make learning-laravel-tdd \ docker \ db \ my.cnf read-only
It seems to be a problem only for Windows
mysqld: [Warning] World-writable config file'/etc/mysql/my.cnf' is ignored. [Docker + Windows] What to do if the docker image of mysql does not start due to a mount error of my.cnf
Checking the application
Finally, run the following command inside the container to see if the application works.
/app # php artisan migrate
