Почему не работает перенаправление в контейнер из nginx?

Доброго времени суток!
Есть два контейнера в одном nginx в другом redmine.
У редмайна открыт порт и если обращаться напрямую на этот порт из браузера, то всё ок.
Поставил контейнер с nginx.
Создал конфиг:
server {
	listen        80;
	server_name  myhost.ru  www.myhost.ru;
	error_log /etc/nginx/logs/debug.log debug;

    location /test {
    	rewrite    ^/test/?([^/]*) /$1 break;
        proxy_pass http://localhost:10083;
        proxy_set_header  Host             $host;
        proxy_set_header  X-Real-IP        $remote_addr;
        proxy_set_header  X-Forwarded-For  $proxy_add_x_forwarded_for;
    }

}

но при обращении на myhost.ru/test получается 502. При этом в логе самого редмайна обращения к нему нет. Что я сделал не так?

лог nginx:

upstream server temporarily disabled while connecting to upstream, client: 10.80.2.244, server: myhost.ru, request: "GET /test HTTP/1.1", upstream: "127.0.0.1:10083", host: "myhost.ru"


Это говорит о том, что не работает ваша опция
proxy_pass http://localhost:10083;

Вы должны заменить localhost, который в контейнере nginx свой и там нет открытого порта 10083, на IP сервера в котором работают оба контейнера.

Другой способ: запускать nginx-контейнер с ключем "--network=host" (в старых версиях докера --net=host). В этом случае в nginx-контейнере будут сети хост-машины и там будет доступен порт 10083 на localhost.
