Docker Nginx映像已启动，但失败，错误为“端口已在使用中”

Question

我有带有alphine-nginx图像的Docker容器。我将5个Nginx配置文件推送到此容器中，但是它不起作用，并且由于容器内部出现“端口已在使用中”而失败。每个配置文件包含一个不同的端口，但启动时失败。

error.log具有：

据我所知，有些东西启动了Nginx，但是如何检查它呢？

Docker ps：

Answer 1

我认为是码头工人。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 9取消此过程。

已更新：我尝试通过docker run nginx:1.17.4-alpine运行容器，没有任何问题。如果您构建自定义图像或使用与默认设置不同的其他设置或配置，则需要对其进行描述。
