用于反向代理和服务的多个 Docker-Compose 文件

Question

我创建了两个 docker-compose 文件，第一个创建了一个 nginx-proxy 和一个 letsencrypt-nginx-proxy-companion。另一个 yaml 文件创建了一个 nextcloud 实例（带有 mariadb）。前两个容器启动时没有错误并且可以正常工作，但在启动第二个 compose 文件后，出现以下警告：

Found orphan containers (test-proxy, test-letsencrypt) for this project. If you removed or renamed this service in your compose file, you can run this command with the --remove-orphans flag to clean it up.

这是我的撰写文件：

nginx-测试.yml

如果我在一个 yml 文件中启动所有四个容器，则一切都会启动，并且我可以通过 nextcloud.localhost 访问 nextcloud。我应该在 yml 文件中进行哪些更改，以便四个容器可以相互交互？
