如何在Docker中链接PostgreSQL容器和PgAdmin？

我有一个docker compose文件，在我的Laravel项目中提供postgres和pgadmin服务。问题是，当我执行数据库迁移时，它会成功，但当我转到pgadmin时，我看不到在那里创建的表。我想，和往常一样，我在写docker compose时犯了一个错误，我就是找不到我遗漏的东西

pgadmin:

在pgadmin中，添加新服务器时，需要将“host.docker.internal”（在Windows上）定义为主机（）。

因为它们都位于同一个docker网络上，所以使用其他服务的名称作为主机名应该有效，如中所述。我不会为一个普通的容器间调用回主机。
