dockerでwordpress ワンパンで構築

2018年11月22日2018年11月26日

docker swamを利用してすぐにサービスを開始できるようにしました。

docker swarmが有効になっていない場合は有効にするために以下のコマンドを実行します。

docker swarm init

yamlを作成するに当たって、以下のサイトを参考しました

永続化はされていないので注意してください。

nginx設定ファイル

cat ./mysite.template
server {
	listen 80;
	server_name ;
	index index.php;
	root /var/www/html;
	location ~* /wp-config.php {
		deny all;
	}
	location ~ \.php$ {
		fastcgi_pass   ${PHP_APP_HOST}:9000;
		fastcgi_index  index.php;
		fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
		include        fastcgi_params;
	}
	location @wordpress {
		fastcgi_pass ${PHP_APP_HOST}:9000;
		fastcgi_index index.php;
		fastcgi_split_path_info ^(.+\.php)(.*)$;
		fastcgi_param SCRIPT_FILENAME $document_root/index.php;
		include fastcgi_params;
	}
	location / {
		try_files $uri $uri/ @wordpress;
	}
}

サービスを作成するには次のコマンドで実行できます。

docker stack deploy -c ./eginx.yml wordpress_enginx
Ignoring unsupported options: restart
Creating network wordpress_enginx_default
Creating service wordpress_enginx_web
Creating service wordpress_enginx_wordpress
Creating service wordpress_enginx_mysql

webブラウザでアクセスすると初期状態で起動しています。

abコマンドで見てみます

nginxで動いてます。逆も然りで、apacheもymlを変えれば動きます。
