CakePHPの開発環境をDockerで構築する

CakePHP

2019.06.26

はじめまして。今年4月に入社したkyamashitaです。主にバックエンド担当になります。初執筆ということで緊張しておりますが、どうぞよろしくお願いします。

Webフレームワークはいくつか触ったことありますが、 CakePHPは今回が初だったため、とりあえず試せるような環境が欲しいと思い、Dockerで構築しました。

構成


[root@localhost:/docker/cake]
# tree 
.
├── build
│   └── cake_php
│       └── Dockerfile
├── config
│   ├── mysql
│   │   └── my.cnf
│   └── nginx
│       └── default.conf
├── data ※ここにCakeのリソースとMySQLのデータを保持しています。
└── docker-compose.yml

起動

コンテナを起動します。


cd /docker/cake
docker-compose up

ホストから各コンテナへは下記でアクセスします。


docker exec -it cake_php bash
docker exec -it cake_db bash
docker exec -it cake_nginx sh

CakePHPアプリ作成


[host]
docker exec -it cake_php bash
[container]
cd /var/www/html
composer create-project --prefer-dist cakephp/app .

データベースの接続情報を変更


vi /var/www/html/config/app.php
Datasources を変更します。
変更箇所抜粋
'Datasources' => [
  'host' => '172.26.0.4', ※docker-compose.ymlで指定したMySQLのアドレス
  'username' => 'admin',
  'password' => 'admin',
  'database' => 'cake',
]

ブラウザに http://ホストのIP:8080 でアクセスすると、 welcomeページが表示され、データベース接続もされていることが確認できます。

やはりDockerは楽で良いですね。
