尝试启动 docker 个容器时出错
Error when trying to up docker containers
我已经解决这个问题 2 天了，尝试了很多在互联网上找到的解决方案，但没有人解决我的问题...我很沮丧，我希望有人能帮助我。
我在 Linux，但我对服务器端口、主机等一无所知
这个项目好像使用了API平台，不知道有没有用。
我不知道如何启动我刚收到的这个项目。我在启动容器时遇到问题 (docker-compose up) :
Error thrown while running command "doctrine:schema:update -f". Message: "An exception occurred in driver: SQLSTATE[08006] [7] could not connect to server: Connection refused
Is the server running on host "localhost" (127.0.0.1) and accepting
php_1 | TCP/IP connections on port 5432?
php_1 | could not connect to server: Address not available
php_1 | Is the server running on host "localhost" (::1) and accepting
php_1 | TCP/IP connections on port 5432?"
好像是容器无法和DB容器通信。但是我不知道该怎么做才能解决这个问题。

我不知道你们是否需要更多东西。告诉我你需要什么。
非常感谢...
您必须使用 db 作为数据库主机，而不是 DATABASE_URL 应用程序环境中的 localhost。

您必须使用 db 作为数据库主机，而不是 DATABASE_URL 应用程序环境中的 localhost。
