nginx docker容器作为运行在docker容器中的服务的反向代理。

我有一个nginx运行在docker容器中,我想把它作为docker容器中服务的反向代理。目前我有两个服务,django和owncloud。

这两个服务在访问它们的目录时都能正常工作,如 localhost:4000localhost:5000.

当我进入 localhost/owncloud 我得到 502 Bad Gateway Nginx日志。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"

当我访问 localhost/django 我得到 page not found Django,这是很好的,但如果我尝试访问Django的 localhost/django/admin 我得到 page not found 来自Nginx。Nginx日志。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"

我是新来的Nginx用户,我在Nginx上乱搞了一番。nginx.conf 很多都没有成功。下面是相关文件。

解决方案:

你将需要多个变化,尝试使用以下步骤:-。

在你的Internal-cloud的docker-compose文件中,添加行。container_name: owncloud 比如:

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

在你的nginx文件中,删除重写行。

    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
    }

如果这对你有效,请告诉我。
