Docker Compose尝试创建重复的容器

Question

我正在使用Docker Compose设置多个服务，以便它们可以通过公共网络与每个服务进行通信。调用命令docker-compose up

时遇到问题

Docker版本：Docker版本19.03.5，内部版本633a0ea

错误：

Creating network "was-kerberos-database_krbnet" with the default driver

似乎docker compose试图启动was-kerberos-database_websphere_1实例的两个重复实例。然后就遇到了问题，因为两个端口都绑定了相同的端口。

我已经运行sudo lsof -i -P -n | grep 9443来查看是否有其他东西正在使用该端口，而没有任何作用。
