用於反向代理和服務的多個 Docker-Compose-Files

Question

我建立了兩個 docker-compose 文件，第一個檔案建立了 nginx-proxy 和 Letsencrypt-nginx-proxy-companion。另一個 yaml 檔案建立一個 nextcloud 實例（使用 mariadb）。前兩個容器啟動時沒有錯誤並工作，但啟動第二個撰寫文件後，出現以下警告：

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.

這是我的撰寫文件：

nginx-test.yml

version: '3.5' 

services:

  proxy:

如果我在一個 yml 檔案中啟動所有四個容器，一切都會啟動，並且我可以透過 nextcloud.localhost 存取 nextcloud。我應該在 yml 檔案中更改哪些內容，以便四個容器可以相互互動？
