Docker Desktop上でKubernetesとHelmを使用して、Laravel 11 + Nginx + MySQL 8.0の環境を構築する手順を提供します。コンテナイメージは1から作成します。
まず、必要なディレクトリ構造を作成します：
mkdir -p laravel-k8s/{charts,docker}
cd laravel-k8s- Dockerfileの作成（Laravel 11 + PHP 8.2）
cat << EOF > docker/Dockerfile
FROM php:8.2-fpm
# Install dependencies
RUN apt-get update && apt-get install -y \
build-essential \
libpng-dev \
libjpeg62-turbo-dev \
libfreetype6-dev \
locales \
zip \
jpegoptim optipng pngquant gifsicle \
vim \
unzip \
git \
curl \
libzip-dev
# Clear cache
RUN apt-get clean && rm -rf /var/lib/apt/lists/*
# Install extensions
RUN docker-php-ext-install pdo_mysql zip exif pcntl
RUN docker-php-ext-configure gd --with-freetype --with-jpeg
RUN docker-php-ext-install gd
# Install composer
RUN curl -sS https://getcomposer.org/installer | php -- --install-dir=/usr/local/bin --filename=composer
# Set working directory
WORKDIR /var/www
# Install Laravel
RUN composer create-project --prefer-dist laravel/laravel:^11.0 .
# Copy existing application directory contents
COPY . /var/www
# Copy existing application directory permissions
COPY --chown=www-data:www-data . /var/www
# Change current user to www
USER www-data
# Expose port 9000 and start php-fpm server
EXPOSE 9000
CMD ["php-fpm"]
EOF- Nginxの設定ファイル作成
cat << EOF > docker/nginx.conf

listen 80;
index index.php index.html;
error_log /var/log/nginx/error.log;

}
location / {

gzip_static on;
}
}

EOF- アプリケーションのビルドとデプロイ
# Dockerイメージのビルド
docker build -t laravel-app:latest -f docker/Dockerfile .
# Kubernetesコンテキストの設定（Docker Desktop）
kubectl config use-context docker-desktop
# Helmチャートのインストール
helm install laravel-app ./charts/laravel-appこれで、Laravel 11 + Nginx + MySQL 8.0の環境がKubernetes上に構築されます。アプリケーションにアクセスするには、以下のコマンドを実行してポートフォワーディングを設定します：
kubectl port-forward svc/laravel-app 8080:80その後、ブラウザで http://localhost:8080 にアクセスすると、Laravelのウェルカムページが表示されるはずです。
注意：この設定は開発環境用です。本番環境では、セキュリティ設定やリソース割り当てなどを適切に調整する必要があります。
