我需要将Apache配置移动到K8s Nginx入口控制器，我在这部分卡住了：

<Directory /var/www/html/motos>
  RewriteRule ^/?.+Portal/index.php(.*)$ /motos/auto_portal/index.php$1
  RewriteRule ^/?.+Portal/private/?(.*)$ /motos/auto_portal/private/$1
  RewriteRule ^/?.+Portal/scripts/?(.*)$ /motos/auto_portal/scripts/$1
  RewriteRule ^/?.+Portal/graphics/?(.*)$ /motos/auto_portal/graphics/$1
</Directory>

看起来我可以在注解中定义它，但我找不到很好的例子来说明如何做到这一点。
