Nginx-Docker-Container akzeptiert keine Anfrage

Question

Ich versuche, einen Nginx-Webserver auf einem Docker-Container auszuführen. Was ich getan habe:

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

Dann docker pswird angezeigt, dass der Container läuft. Außerdem wird getestet, dass Nginx aktiv ist:

$ 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

Netstat:

Ich verwende Fedora 34. Auch das Ausführen von Nginx auf meinem System (nicht Docker) auf demselben Port funktioniert einwandfrei.

Mein /etc/nginx/nginx.conf:

    include /etc/nginx/conf.d/*.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;
    }

}

Der letzte unten ist der entsprechende Server.

Answer 1

Das Nginx-Image stellt Port 80 bereit, nicht 8080.

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

Answer 2

Das Problem war die Firewall. Unter Fedora:

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

Bei anderen kann es sein:

sudo ufw allow 8080
