Nginx docker 容器不接受请求

我正在尝试在 Docker 容器上运行 Nginx Web 服务器。我做了以下操作：

$ docker pull nginx
$ docker run -d -p 8080:8080 --name nginx1 nginx

然后docker ps显示容器正在运行。同时测试 nginx 是否启动：

$ docker exec -it nginx1 bash
root@...:/# service nginx status
[ ok ] nginx is running.
root@...:/# curl http://localhost:8080/

{Shows the content of html file located on /etc/nginx/html/index.html}

root@...:/# exit
exit
$ curl http://localhost:8080/

{Just loads and nothing happens} <- This is my problem

网络状态：

我在 Fedora 34 上。在我的系统上（不是 Docker）在同一个端口上运行 Nginx 也可以正常工作。

我的/etc/nginx/nginx.conf：

    server {
        listen       80;
        listen       [::]:80;
        server_name  _;
        root         /usr/share/nginx/html;

        # Load configuration files for the default server block.
        include /etc/nginx/default.d/*.conf;

        error_page 404 /404.html;
        location = /404.html {
        }

        error_page 500 502 503 504 /50x.html;
        location = /50x.html {
        }
    }

    server {
        listen 8080;
    }

}

最底部的最后一个是相关服务器。

答案1

nginx 镜像公开的是端口 80，而不是 8080。

docker run -d -p 8080:80 --name nginx1 nginx

答案2

防火墙是问题所在。在 Fedora 上：

sudo firewall-cmd --zone=dmz --add-port=8080/tcp

在其他情况下可能是：

sudo ufw allow 8080
