django - 运行Django项目的Docker NGINX设置给出无效的端口规范错误

Question

我正在尝试为我的django项目设置Docker。我相信所有设置都可以在我的机器上运行docker。当前，docker version提供以下输出:

Client version: 1.6.2
Client API version: 1.18
Go version (client): go1.2.1
Git commit (client): 7c8fca2
OS/Arch (client): linux/amd64
Server version: 17.05.0-ce
Server API version: 1.29
Go version (server): go1.7.5
Git commit (server): 89658be
OS/Arch (server): linux/amd64

我已经按照以下步骤设置了 docker-compose.yml文件:

version: '3'
services:
  nginx:
    restart: always
    image: nginx:latest
    container_name: NGINX
    ports:
      - "8000:8000"
    volumes:
      - ./src:/src
      - ./config/nginx:/etc/nginx/conf.d
      - /static:/static
    depends_on:
      - web
  web:
    restart: always
    build: .
    container_name: DJANGO
    command: bash -c "python manage.py makemigrations && python manage.py migrate && gunicorn loop.wsgi -b 0.0.0.0:8000 --reload"
    depends_on:
      - db
    volumes:
      - ./src:/src
      - /static:/static
    expose:
      - "8000"

  db:
    restart: always
    image: postgres:latest
    container_name: PSQL

docker-compose build成功构建了docker镜像并显示以下消息:

Successfully built 6b13b02488dc
Successfully tagged loopserver_web:latest
nginx uses an image, skipping

但是，当我尝试运行 docker-compose up时，发生以下错误:

Creating NGINX ... 
Creating NGINX ... error

ERROR: for NGINX  Cannot create container for service nginx: invalid port specification: "None"

ERROR: for nginx  Cannot create container for service nginx: invalid port specification: "None"
ERROR: Encountered errors while bringing up the project.

和 server.conf文件夹中的 config/nginx文件。

upstream web {  
  ip_hash;
  server web:8000;
}

# portal
server {  
  location /static/ {    
        autoindex on;    
        alias /static/; 
    }
  location / {
        proxy_pass http://web/;
    }
  listen 8000;
  server_name localhost;
}

我第一次使用 docker，并停留在此错误。任何指导都将非常有帮助。

Answer 1

我将答案留在这里以供将来引用。

正如我们调查的那样，似乎您的docker-compose版本(<1.12.0)中存在python3问题。

错误:https://github.com/docker/compose/issues/4729

他们建议升级到 Python 3.4.4+或3.5.1+ ，并且应该已修复。
