Question

我将jwilder/nginx-proxy与docker-compose.yaml分开使用。它看起来像这样：

proxy:
   image: jwilder/nginx-proxy
   restart: always
   volumes:
     - /var/run/docker.sock:/tmp/docker.sock:ro
     - ./nginx/conf.d/proxy.conf:/etc/nginx/conf.d/proxy.conf:ro
     - /Users/marcin/Docker/local_share/certificates:/etc/nginx/certs:ro      
   ports:
     - "80:80"
     - "443:443"
   container_name: proxy

我正在使用它已经很长时间了，当我的项目docker-compose.yaml看起来像这样时它工作正常：

web:
  build: /Users/marcin/Docker/definitions/php-nginx/php-7.1-ubuntu
  volumes:
    - /Users/marcin/Docker/projects/test.local/html/:/usr/share/nginx/html/
    - /Users/marcin/Docker/projects/test.local/nginx/conf.d/:/etc/nginx/conf.d/
    - /Users/marcin/Docker/projects/test.local/nginx/log/:/var/log/nginx/
    - /Users/marcin/Docker/projects/test.local/supervisor/conf.d/:/etc/supervisor/conf.d/
    - /Users/marcin/Docker/projects/test.local/supervisor/log/:/var/log/supervisor/
    - /Users/marcin/Docker/projects/test.local/cron/:/root/.cron/
    - /Users/marcin/Docker/local_share/:/root/.local_share/
    - /Users/marcin/Docker/local_share/certificates/:/usr/share/nginx/certificates/  
  working_dir: /usr/share/nginx/html/
  links:
    - db
  container_name: test.php
  hostname: test.local
  ports:
    - "336:22"
    - "8081:80"
    - "18080:443"    
  environment:
    - VIRTUAL_HOST=test.local   
    - CERT_NAME=default
    - HTTPS_METHOD=noredirect
db:
  build: /Users/marcin/Docker/definitions/mysql/5.7
  environment:
     - MYSQL_ROOT_PASSWORD=pass
     - MYSQL_DATABASE=
     - MYSQL_USER=
     - MYSQL_PASSWORD=
  expose:
     - 3306
  volumes:
    - /Users/marcin/Docker/projects/test.local/mysql/data/:/var/lib/mysql/
    - /Users/marcin/Docker/projects/test.local/mysql/conf.d/:/etc/mysql/conf.d/source
    - /Users/marcin/Docker/projects/test.local/mysql/log/:/var/log/mysql/
  ports:
    - "33060:3306"
  container_name: test.db
  hostname: test.local

我可以使用http://test.local或https://test.local预期访问网站而不会出现任何问题。

但是我必须将我的文件结构更新为更新的版本：

version: "3.2"
services:
  web:
    build: /Users/marcin/Docker/definitions/php-nginx/php-7.1-ubuntu
    volumes:
      - /Users/marcin/Docker/projects/test.local/html/:/usr/share/nginx/html/
      - /Users/marcin/Docker/projects/test.local/nginx/conf.d/:/etc/nginx/conf.d/
      - /Users/marcin/Docker/projects/test.local/nginx/log/:/var/log/nginx/
      - /Users/marcin/Docker/projects/test.local/supervisor/conf.d/:/etc/supervisor/conf.d/
      - /Users/marcin/Docker/projects/test.local/supervisor/log/:/var/log/supervisor/
      - /Users/marcin/Docker/projects/test.local/cron/:/root/.cron/
      - /Users/marcin/Docker/local_share/:/root/.local_share/
      - /Users/marcin/Docker/local_share/certificates/:/usr/share/nginx/certificates/  
    working_dir: /usr/share/nginx/html/
    links:
      - db
    container_name: test.php
    hostname: test.local
    ports:
      - "336:22"
      - "8081:80"
      - "18080:443"    
    environment:
      - VIRTUAL_HOST=test.local   
      - CERT_NAME=default
      - HTTPS_METHOD=noredirect
  db:
    build: /Users/marcin/Docker/definitions/mysql/5.7
    environment:
       - MYSQL_ROOT_PASSWORD=pass
       - MYSQL_DATABASE=
       - MYSQL_USER=
       - MYSQL_PASSWORD=
    expose:
       - 3306
    volumes:
      - /Users/marcin/Docker/projects/test.local/mysql/data/:/var/lib/mysql/
      - /Users/marcin/Docker/projects/test.local/mysql/conf.d/:/etc/mysql/conf.d/source
      - /Users/marcin/Docker/projects/test.local/mysql/log/:/var/log/mysql/
    ports:
      - "33060:3306"
    container_name: test.db
    hostname: test.local

之后似乎没有用。我可以使用ip和端口访问网站没有问题，但我不能再使用域来访问它。当我尝试我得到时：

503服务暂时不可用

的nginx / 1.13.8

这肯定来自jwilder nginx（而不是项目中的nginx）。

所以问题是 - 我应该在哪里放置环境变量才能使其工作？似乎当它们被放置时，它们不会被代理读取。

503表示nginx-proxy容器可以看到您的容器在docker中运行，并且它具有nginx为其路由流量所需的配置，但它无法通过docker网络连接到该容器。 要使容器到容器网络正常工作，您需要定义一个通用的docker网络。您应首先运行以下命令来创建网络：

docker network create proxy

然后更新你的nginx-proxy撰写文件以使用网络（这也应该升级到至少一个v2语法，我已经用3.2来匹配你的其他文件）：

version: "3.2"

networks:
  proxy:
    external: true

services:
  proxy:
    image: jwilder/nginx-proxy
    restart: always
    volumes:
      - /var/run/docker.sock:/tmp/docker.sock:ro
      - ./nginx/conf.d/proxy.conf:/etc/nginx/conf.d/proxy.conf:ro
      - /Users/marcin/Docker/local_share/certificates:/etc/nginx/certs:ro      
    ports:
      - "80:80"
      - "443:443"
    container_name: proxy
    networks:
      - proxy

然后为您的应用做类似的事情：

version: "3.2"
networks:
  proxy:
    external: true
services:
  web:
    build: /Users/marcin/Docker/definitions/php-nginx/php-7.1-ubuntu
    volumes:
      - /Users/marcin/Docker/projects/test.local/html/:/usr/share/nginx/html/
      - /Users/marcin/Docker/projects/test.local/nginx/conf.d/:/etc/nginx/conf.d/
      - /Users/marcin/Docker/projects/test.local/nginx/log/:/var/log/nginx/
      - /Users/marcin/Docker/projects/test.local/supervisor/conf.d/:/etc/supervisor/conf.d/
      - /Users/marcin/Docker/projects/test.local/supervisor/log/:/var/log/supervisor/
      - /Users/marcin/Docker/projects/test.local/cron/:/root/.cron/
      - /Users/marcin/Docker/local_share/:/root/.local_share/
      - /Users/marcin/Docker/local_share/certificates/:/usr/share/nginx/certificates/  
    working_dir: /usr/share/nginx/html/
    links:
      - db
    container_name: test.php
    hostname: test.local
    ports:
      - "336:22"
      - "8081:80"
      - "18080:443"    
    environment:
      - VIRTUAL_HOST=test.local   
      - CERT_NAME=default
      - HTTPS_METHOD=noredirect
    networks:
      - proxy
      - default
  db:
    build: /Users/marcin/Docker/definitions/mysql/5.7
    environment:
       - MYSQL_ROOT_PASSWORD=pass
       - MYSQL_DATABASE=
       - MYSQL_USER=
       - MYSQL_PASSWORD=
    expose:
       - 3306
    volumes:
      - /Users/marcin/Docker/projects/test.local/mysql/data/:/var/lib/mysql/
      - /Users/marcin/Docker/projects/test.local/mysql/conf.d/:/etc/mysql/conf.d/source
      - /Users/marcin/Docker/projects/test.local/mysql/log/:/var/log/mysql/
    ports:
      - "33060:3306"
    container_name: test.db
    hostname: test.local

如果您从v1语法升级（没有定义版本），您会发现docker切换到运行同一网络上的所有内容而没有dns来运行每个compose项目或使用dns在专用网络上堆栈。要在其他网络上运行您的应用，您需要明确配置它。在上面的示例中，只有Web容器放置在代理网络上，并且两者都位于为此项目或堆栈创建的默认网络上。
