Jwilder Nginx代理-Docker撰写结构更新后的503 [英] Jwilder nginx proxy - 503 after docker compose structure update

问题描述

我正在将 jwilder/nginx-proxy 与单独的 docker-compose.yaml 结合使用.看起来像这样:

I'm using jwilder/nginx-proxy with separate docker-compose.yaml. It looks like this:

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

我使用了很长时间，当我的项目 docker-compose.yaml 看起来像这样时，它工作正常:

I'm using it for quite a long time and it's working fine when my project docker-compose.yaml looks like this:

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

使用 http://test.local 或 https://test.local 可以毫无问题地访问网站.

I can access site without any problem using http://test.local or https://test.local what is expected.

但是我必须将文件结构更新为较新的版本:

However I had to update my file structure to newer version:

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

，此后似乎不起作用.我可以使用ip和port毫无问题地访问站点，但是我不能再使用域来访问它.当我尝试时会得到:

and after that it seems not to work. I can access site using ip and port without a problem, but I cannot longer use domain to access it. When I try I'm getting:

503服务暂时不可用

503 Service Temporarily Unavailable

nginx/1.13.8

nginx/1.13.8

这肯定是来自jwilder nginx(而不是项目中的nginx).

And this is for sure from jwilder nginx (and not the nginx in project).

问题是-我应该在哪里放置环境变量以使其起作用?看起来当它们按原样放置时，它们不会被代理读取.

So the question is - where should I put environment variables to make it work? It seems that when they are placed as they are at the moment they are not read by proxy.

推荐答案

503表示nginx-proxy容器可以看到您的容器在docker中运行，并且具有nginx路由流量所需的配置，但是无法通过docker网络连接到该容器.要使容器到容器的网络正常工作，您需要定义一个通用的docker网络.首先应运行以下命令来创建网络:

The 503 indicates that the nginx-proxy container can see your container running in docker and it has the configuration needed for nginx to route traffic to it, but it is unable to connect to that container over the docker network. For container-to-container networking to work, you need to have a common docker network defined. You should first run the following to create a network:

docker network create proxy

然后更新您的nginx-proxy撰写文件以使用网络(也应该至少升级到v2语法，我已经使用3.2来匹配其他文件):

Then update your nginx-proxy compose file to use the network (this should also be upgraded to at least a v2 syntax, I've gone with 3.2 to match your other file):

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

然后对您的应用程序执行类似的操作:

And then do something similar for your application:

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

如果要从v1语法升级(未定义版本)，您会发现docker切换为从没有dns的同一网络上运行所有内容，切换到在带有dns的专用网络上运行每个撰写项目或堆栈.要在其他网络上运行您的应用，您需要对其进行显式配置.在上面的示例中，只有Web容器被放置在代理网络上，并且两者都在为此项目或堆栈创建的默认网络上.

If you were upgrading from a v1 syntax (without a version defined), you will find that docker switches from running everything on the same network without dns to running each compose project or stack on a dedicated network with dns. To run your apps on other networks, you'll need to explicitly configure that. In the above example, only the web container was placed on the proxy network, and both are on the default network created for this project or stack.
