我试图为我的本地开发项目准备docker-compose文件，但我坚持为phpmyadmin设置域。
我在windows上添加了主机到主机文件。

127.0.0.1 phpmyadmin.test
127.0.0.1 wordpress1.test
127.0.0.1 worpresss2.test

我的dev文件夹的结构：

     - Dockerfile

     - Dockerfile

   - nginx.conf
   - phpmyadmin.conf

所以，域：wordpress1.test和wordpress2.test工作正常，但当我去phpmyadmin。测试我得到403错误，我不知道，为什么。你能帮助我吗？
顺便说一句.为什么我必须使用构建Dockerfiles而不是写：图像：WordPress：5.5.1-fpm
