config.ini:

[general]
DOCKER_IMAGE_NAME = mysite/mmcsite
ROOT_PASSWORD = root


[production]
SECRET_KEY = putsomethingreallylonghere
HOST =  0.0.0.0                 ; IP address of your production server
USE_PASSWORD = false            ; false = use SSH key authentication; true = use password
USERNAME = root
PASSWORD = (empty)

DATABASE_HOST = 0.0.0.0         ; IP address of your database server

Nginx :

nginx.conf:

server {
    listen 80 default_server;
    access_log /dev/null;
    error_log /logs/nginx/nginx.error.log;


    location /static/ {
        root /;
    }


    # TODO add media directory


    location / {
        proxy_pass_header Server;
        proxy_set_header Host $http_host;
        proxy_redirect off;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Scheme $scheme;
        proxy_connect_timeout 10;
        proxy_read_timeout 10;
        proxy_pass http://127.0.0.1:8000/;
    }
}

搭建好之后：

docker build -t mysite/mmcsite .
docker run -d -p 80:80 -v $(pwd):/code --env DJANGO_PRODUCTION=false mysite/mmcsite
docker ps -a
