Estoy intentando ejecutar un servidor web Nginx en un contenedor acoplable. Que he hecho:
$ docker pull nginx
$ docker run -d -p 8080:8080 --name nginx1 nginx
Luego docker ps
muestra que el contenedor se está ejecutando. También está disponible la prueba de nginx:
$ 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:
tcp 0 0 0.0.0.0:8080 0.0.0.0:* LISTEN 3776/docker-proxy
tcp 0 1 172.17.0.1:36684 172.17.0.2:8080 SYN_SENT 3776/docker-proxy

Estoy en Fedora 34. También ejecutar Nginx en mi sistema (no en Docker) en el mismo puerto funciona bien.
Mi /etc/nginx/nginx.conf
:

El último en la parte inferior es el servidor correspondiente.
Respuesta1
La imagen de nginx expone el puerto 80, no el 8080.
docker run -d -p 8080:80 --name nginx1 nginx
Respuesta2
El problema era el cortafuegos. En sombrero de fieltro:
sudo firewall-cmd --zone=dmz --add-port=8080/tcp
En otros puede ser:
sudo ufw allow 8080
