我目前正在学习 docker，我已经编写了一个 docker-compose 文件，该文件应该启动 nginx、gitea、nextcloud并通过域名作为反向代理将它们全部路由。

除了nextcloud ，一切都很顺利。我可以通过 localhost:3001 访问它，但不能通过 nginx 反向代理。gitea 一切都很好，它可以双向工作。

我得到的错误是：

nginx_proxy     | 2018/08/10 00:17:34 [error] 8#8: *1 connect() failed (111: Connection refused) while connecting to upstream, client: 172.19.0.1, server: cloud.example.ca, request: "GET / HTTP/1.1", upstream: "http://172.19.0.4:3001/", host: "cloud.example.ca"

码头工人-compose.yml：

version: '3.1'

services:

  nginx:
    container_name: nginx_proxy
    image: nginx:latest
    restart: always
    volumes: 
// Here I'm swapping out my default.conf for the container's by mounting my 
directory over theirs.

      MYSQL_USER: gitea
    secrets:

    networks:
      - database

  nextcloud:
    image: nextcloud
    container_name: nextcloud
    ports:
      - 3001:80
    volumes:
      - nextcloud:/var/www/html
    restart: always
    networks:
      - proxy
      - database

  gitea:
    container_name: gitea
    image: gitea/gitea:latest
    environment:
      - USER_UID=1000
      - USER_GID=1000
    restart: always
    volumes:
      - gitea:/data
    ports:
      -  3000:3000
      -  22:22
    networks:
      - proxy
      - database

volumes:
  nextcloud:
  nextcloud_db:
  gitea:
  gitea_db:

networks:
  proxy:
  database:

secrets:
  cloud_db_pass:
    file: cloud_db_pass.txt
  cloud_db_root:
    file: cloud_db_root.txt

我的 default.conf 被挂载到 /etc/nginx/conf.d/default.conf

upstream nextcloud {
         server nextcloud:3001;
}

upstream gitea {
         server gitea:3000;
}

server {
       listen 80;
       listen [::]:80;
       server_name cloud.example.ca;

       location / {
                proxy_pass http://nextcloud;
                }
}

server {
       listen 80;
       listen [::]:80;
       server_name git.example.ca;

       location / {
                proxy_pass http://gitea;
                }
}

我当然有我的主机文件设置来将域路由到本地主机。我做了一些谷歌搜索，但到目前为止我发现的任何东西似乎都与我遇到的情况一致。提前致谢！
