Docker: 8080 没有得到来自 nginx 容器的响应

Question

我正在尝试运行 nginx docker 容器使用以下命令将其 8080 暴露到我的 8080 端口：

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

结果是这样的：

/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

如果我检查 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向 https://localhost:8080 发送请求时，没有响应并无限期地继续加载...

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

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

有什么想法吗？

没有反应似乎很正常，原因有两点：

根据文档(https://hub.docker.com/_/nginx)，内部端口不是8080，而是80；这意味着您应该改为尝试以下命令：
docker run --name mycontainer -p 8080:80 nginx
顺便说一句，它可能比运行:
更可取 docker run --rm -p 8080:80 nginx
考虑到 运行ning 容器是短暂的，并且由于 --rm 选项可以在停止时自动删除（因此将其命名为 --name … 是不必要的），然后在以后重新创建而不会丢失数据，因为持久数据通常存储在所谓的 Docker volumes.
中
然后，你的URL以https://开头，但通常情况下，如果一个容器不涉及专用的TLS反向代理配置，它只接受HTTP请求是正常的（从 http://) 开始；所以你应该尝试浏览以下 URL:
http://localhost:8080

但是如果您特别有兴趣为您的 dockerized 网站提供一些 HTTPS 支持，请参见例如this Whosebug question or browse other questions involving these tags.
