本文介绍如何使用Docker部署Django项目，包括配置sources.list以提高软件下载速度，设置pip.conf加速pip包安装，创建Dockerfile定义镜像构建过程，配置Nginx与Supervisor以实现项目的稳定运行。

需要的文本文件（sources.list, pip.conf, dockerfile, supervisor.conf, nginx.conf, uwsgi.ini与项目中manage.py同级目录）

    django框架的代码    ->    项目文件 

    sources.list    ->    更改基础镜像软件源文件

    pip.conf    ->    更改pip源的文件

    dockerfile    ->    生成镜像引导文件

    nginx.conf    ->    nginx配置文件

    supervisor.conf    ->    supervisor 配置文件

source.list 文件内容（提交软件下载速度）：

deb http://mirrors.aliyun.com/ubuntu/ xenial main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ xenial-security main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ xenial-updates main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ xenial-proposed main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ xenial-backports main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ xenial main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ xenial-security main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ xenial-updates main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ xenial-proposed main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ xenial-backports main restricted universe multiverse

pip.conf （提高pip安装的软件下载速度）：

[global]
index-url = http://mirrors.aliyun.com/pypi/simple/

[install]
trusted-host = mirrors.aliyun.com

dockerfile文件（WORKDIR：等同 cd 命令，COPY ./ ./ ：复制当前目录下所有文件到workdir目录）：

FROM ubuntu:16.04

ADD sources.list /etc/apt/sources.list

RUN apt-get -y update && apt-get install -y nginx supervisor vim python-dev python-pip python-setuptools && apt-get clean all

COPY pip.conf /root/.pip/pip.conf

RUN python -m pip install --upgrade pip && pip install uwsgi

RUN mkdir -p /data/apps/mysite /data/tmp/sock /data/tmp/pid /data/logs/uwsgi /data/logs/nginx

WORKDIR /data/apps/mysite

COPY ./ ./

RUN pip install -r /data/apps/mysite/requirements.txt

RUN ln -s /data/apps/mysite/mysite_nginx.conf /etc/nginx/sites-enabled/

RUN ln -s /data/apps/mysite/supervisord.conf /etc/supervisor/conf.d/

WORKDIR /data

CMD ["/usr/bin/supervisord", "-n"]

* WORKDIR /data 不能去掉，supervisorctl在workdir下没有权限开启

nginx.conf (nginx配置文件)：

server{
    listen 8000;
    server_name localhost;
    charset utf-8;
    client_max_body_size 75M;

    location / {
        uwsgi_pass unix:///data/tmp/sock/mysite.sock;
        include /etc/nginx/uwsgi_params;
    }
}

supervisor.conf (supervisor 配置文件)：

[program:nginx]
command = /usr/sbin/nginx -g 'daemon off';
autostart = true
autorestart = true
stdout_logfile = /data/logs/nginx/nginx_out.log
stderr_logfile = /data/logs/nginx/nginx_err.log

[program:uwsgi]
command = /usr/local/bin/uwsgi --ini /data/apps/mysite/mysite_uwsgi.ini
autostart = true
autorestart = true
stdout_logfile = /data/logs/uwsgi/uwsgi_out.log
stderr_logfile = /data/logs/uwsgi/uwsgi_err.log

uwsgi.ini (uwsgi 配置文件)：

[uwsgi]
chdir = / data / apps / mysite
module = mysite.wsgi.application
master = true
processes = 2
socket = / data / tmp / sock / mysite.sock
pidfile = / data / tmp / pid / mysite.pid
chmod - socket = 666
vacuum = true

在manage.py文件目录下执行的docker命令：

docker pull ubuntu:16.04    拉直ubuntu基础镜像

docker build -t djangotest:01 .    生成tag为01 name为djangotest的镜像

docker run djangotest:01    运行项目

docker exec -it 容器id /bin/bash    进入容器查看项目运行情况
