Nginx for multiple Docker Container - docker

Question

I want to implement different ports for different docker containers . If request to 8080 port ,it should go nginx container and so on.
my docker-compose file
version: "3"
services:
ngnix:
image: nginx
ports:
- "8080:80"
volumes:
- ./nginx.conf/:/etc/nginx/nginx.conf
command: [nginx-debug, "-g", "daemon off;"]
apache:
image: httpd
command: bash -c "httpd -D FOREGROUND"
ports:
- "8081:80"
and my nginx.conf file below :
worker_processes 1;
events { worker_connections 1024; }
http {
sendfile on;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Host $server_name;
server {
listen 8080;
server_name localhost;
location / {
proxy_pass http://127.0.0.1:8080;
proxy_redirect off;
}
}
server {
listen 8081;
server_name localhost;
location / {
proxy_pass http://127.0.0.1:8081;
proxy_redirect off;
}
}
}
But it does not work .Where is my mistake I spent my all time ?
