Port Mapping
If you'd like to be able to access the instance from the host without the container's IP, standard port mappings can be used. Just add -p 3000:3000 to the docker run arguments and then access either localhost:3000 or host-ip:3000 in a browser.

iptables -t nat -A PREROUTING -d 4.4.4.100 -p tcp -m tcp --dport 2222 -j DNAT --to-destination 192.168.100.100:22

server {
    listen 8080;
    server_name my-server.ru ;

   location /auth {
        proxy_pass http://auth_service:8081;
....
   location /api {
        proxy_pass http://api_service:8082;
