Контейнер nginx docker в качестве обратного прокси для служб, работающих в контейнерах docker

У меня nginx работает в docker контейнере, который я хочу использовать в качестве обратного прокси для сервисов, работающих в docker контейнерах. У меня есть две службы: django и owncloud.

Обе службы работают при обращении к ним, например, localhost:4000 и localhost:5000.

Когда я получаю доступ к localhost/owncloud, я получаю 502 Bad Gateway
Nginx log:
2020-04-27T13:21:54.852082794Z 2020/04/27 13:21:54 [error] 6#6: *2 connect() failed (111: Connection refused) while connecting to upstream, client: 172.18.0.1, server: , request: "GET /owncloud/ HTTP/1.1", upstream: "http://172.18.0.4:4000/", host: "localhost"

Когда я получаю доступ к localhost/django, я получаю page not found от Django, что хорошо, но я, если я пытаюсь для доступа localhost/django/admin я получаю page not found из Nginx.
Nginx log:
2020-04-27T13:29:11.173933857Z 2020/04/27 13:29:11 [error] 6#6: *4 "/etc/nginx/html/sv/admin/index.html" is not found (2: No such file or directory), client: 172.18.0.1, server: , request: "GET /sv/admin/ HTTP/1.1", host: "localhost"

Я новичок в Nginx и перепутался с nginx.conf много без успеха. Вот соответствующие файлы:

Вам понадобится несколько изменений, попробуйте выполнить следующие шаги: -

В вашем внутреннем облаке docker -составьте файл, добавьте строку container_name: owncloud Например: 

internal-owncloud:
image: owncloud/server:${OWNCLOUD_VERSION}
restart: unless-stopped
container_name: owncloud #add this line
ports:
  - ${HTTP_PORT}:8080
depends_on:
  - db
  - redis
environment:
  - OWNCLOUD_DOMAIN=${OWNCLOUD_DOMAIN}
  - OWNCLOUD_DB_TYPE=mysql
  - OWNCLOUD_DB_NAME=owncloud
  - OWNCLOUD_DB_USERNAME=owncloud
  - OWNCLOUD_DB_PASSWORD=owncloud
  - OWNCLOUD_DB_HOST=db
  - OWNCLOUD_ADMIN_USERNAME=${ADMIN_USERNAME}
  - OWNCLOUD_ADMIN_PASSWORD=${ADMIN_PASSWORD}
  - OWNCLOUD_MYSQL_UTF8MB4=true
  - OWNCLOUD_REDIS_ENABLED=true
  - OWNCLOUD_REDIS_HOST=redis
healthcheck:
  test: ["CMD", "/usr/bin/healthcheck"]
  interval: 30s
  timeout: 10s
  retries: 5
volumes:
  - files:/mnt/data      
networks: 
  - nginx-net

В вашем файле nginx удалите строки перезаписи: 

    location /django/ {
        proxy_pass http://django:5000;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        #rewrite ^/django(.*)$ $1 break; //remove this
    }
    location /owncloud/ {
        proxy_pass http://owncloud:8080;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        #rewrite ^/owncloud(/.*)$ $1 break; //remove this
    }

Дайте мне знать, если это работает для вас.
