Docker: 8080没有得到nginx容器的响应

Question

我正在尝试运行一个nginx docker容器，使用以下命令将其8080暴露给我的8080端口:

docker run --name mycontainer -p 8080:8080 nginx

结果如下:

/docker-entrypoint.sh: /docker-entrypoint.d/ is not empty, will attempt to perform configuration
/docker-entrypoint.sh: Looking for shell scripts in /docker-entrypoint.d/
/docker-entrypoint.sh: Launching /docker-entrypoint.d/10-listen-on-ipv6-by-default.sh

如果检查docker ps:

CONTAINER ID   IMAGE     COMMAND                  CREATED         STATUS         PORTS                                               NAMES
7ccaaa84ftaf   nginx     "/docker-entrypoint.…"   7 minutes ago   Up 7 minutes   80/tcp, 0.0.0.0:8080->8080/tcp, :::8080->8080/tcp   proxy

但是当在我的浏览器中发送请求到https://localhost:8080时，没有响应并无限期地继续加载…

检查容器docker exec -it proxy bash中的nginx服务:

root@******:/# service nginx status
[ ok ] nginx is running.

任何想法?

Pd。我是docker新手，使用ubuntu。

似乎没有响应是正常的，因为以下两点:

• 根据文档(https://hub.docker.com/_/nginx)，内部端口不是8080，而是80;这意味着您应该尝试以下命令:
  docker run --name mycontainer -p 8080:80 nginx
  顺便说一句，考虑到正在运行的容器是短暂的，最好运行:
  docker run --rm -p 8080:80 nginx
  ，并且由于--rm选项(因此将其命名为--name …是不必要的)，可以在停止时自动删除，然后在没有数据丢失的情况下重新创建，因为持久数据通常存储在所谓的Docker卷中。

• 然后，您的URL以https://开始，但通常，如果容器不涉及专用的TLS反向代理配置，它只接受HTTP请求(从http://开始)是正常的;因此，您应该尝试浏览以下URL:
  http://localhost:8080

但是如果你特别有兴趣为你的dockerized网站提供一些HTTPS支持，参见例如这个StackOverflow问题或浏览涉及这些标签的其他问题。
