Docker compose：mariadb 的 getaddrinfo 失敗
我不擅長建立 docker-compose，目前在嘗試建置新專案時遇到問題。
建置後，我無法存取 php 應用程式容器中的 mariadb 伺服器，出現此錯誤：
PDO::__construct(): php_network_getaddresses: mariadb 的 getaddrinfo 失敗：名稱無法解析
所以我知道有些東西配置錯誤，但我還不知道是什麼。我嘗試了很多改變，但沒有任何效果。
這是我目前的 docker-compose.yml：
version: "3.8"
networks:
# used by some services (php) to communicate with other docker-compose.yaml
censored.com:
external:

有人可以幫我解決這個問題嗎？
謝謝！
