Docker Nginx映像启动，但失败并出现错误；“已在使用的端口”；

我有带图像的docker容器。我将5个Nginx配置文件推送到这个容器中，但它不工作，并且由于容器中的“端口已在使用”而失败。每个配置文件都包含不同的端口，但启动时失败

错误。日志有：

正如我看到的，Nginx启动了一些东西，但是如何检查它是什么呢

Docker ps:
您有一个id为（PID）的进程，该进程占用了该端口。
您可以使用
ps-p9-ocomm=
获取此进程的命令行

我想是docker。在这种情况下，请尝试
docker ps
获取正在运行的docker容器的列表

您可以通过
kill-9
终止这个进程

更新：我已尝试通过
docker run nginx:1.17.4-alpine运行容器，但没有任何问题。如果您生成自定义映像或使用与默认值不同的其他设置或配置，则需要对其进行说明。
将
docker ps
结果添加到问题中显示您的dockerfile，似乎Nginx尝试重新启动，而另一个进程或Nginx已占用该端口。@adii我已在此处添加了它，请检查主文件是否丢失
/opt/startup.sh
@adii是的，对不起，忘记了@adii我应该注意，对于其他同事，它启动时没有任何问题。我想这对docker来说并不重要，因为容器化，但在Windows10和Ubuntu18.04（客户端）上它可以工作，在macOS上它不能工作。
