使用docker-compose+nginx+uwsgi+django部署项目

（1）centos上下载docker + docker-compose

（2）基础目录

（3）首先创建一个纯净的python+django+uwsgi的镜像，便于后期使用（也可不用创建，后期docker-compose的时候再创建python镜像，这里我们先创建，后期直接把项目放进去，不用每次都下载环境）

         创建python+django+uwsgi的纯净镜像，命名镜像名为django：

#Dockerfile  这个dockrfile不是基础目录中的Dockerfile，需要在其他目录中创建

FROM python
RUN mkdir /code
WORKDIR /code
ADD requirements.txt . /code
RUN pip3 install -i https://pypi.tuna.tsinghua.edu.cn/simple -r requirements.txt
RUN rm -f requirements.txt

    #requirements.txt

django==2.2.2
psycopg2
uwsgi

（4）基础目录中的Dockerfile

#使用刚刚创建的基础镜像django

FROM django
WORKDIR /code
RUN mkdir hello   #创建项目目录
ADD . /code/hello

 （5）创建uwsgi配置文件

         创建conf/uwsgi.ini配置文件

#conf/uwsgi.ini

[uwsgi]
socket = 0.0.0.0:8000
chdir = /code/hello
module = hello.wsgi
#daemonize = uwsgi.log
master = True
processes = 4

 （6）创建nginx配置文件

         创建nginx/nginc.conf

#nginx/nginx.conf
events {
    worker_connections  1024;
}
http {
    include       mime.types;
    default_type  application/octet-stream;
    sendfile        on;
    server {
        listen 80;
        charset utf-8;
        location / {
           include uwsgi_params;
           uwsgi_pass 10.127.2.3:8000;  #端口要和uwsgi里配置的一样
           #uwsgi_param UWSGI_SCRIPT hello.wsgi;  #wsgi.py所在的目录名+.wsgi
           #uwsgi_param UWSGI_CHDIR /opt/deploy/hello; #项目路径

        }
        location /static/ {
        alias /code/hello/static/; #静态资源路径
        }
    }

 (7)创建nginx的Dockerfile

      创建nginx/Dockerfile

#nginx/Dockerfile

FROM nginx

WORKDIR /etc/nginx/
RUN cp nginx.conf ./nginx.conf.bak
COPY nginx.conf ./

CMD ["nginx", "-g", "daemon off;"]

 (8)创建docker-compose.yml

version: '3'

services:
  db:
    image: postgres
    restart: always
    environment:
      POSTGRES_PASSWORD: 12345
    networks:
      net-django:
        ipv4_address: 10.127.2.4

  web:
    build: .
    #command: python3 manage.py runserver 0.0.0.0:8000
    privileged: true
    #ports:
    #  - 8000:8000
    depends_on:
      - db
    networks:
      net-django:
        ipv4_address: 10.127.2.3
    #command: uwsgi --chdir=/code/hello --module=hello.wsgi --master --socket 0.0.0.0:8000
    command: uwsgi --ini /code/hello/conf/uwsgi.ini

  nginx:
    container_name: nginx-container
    restart: always
    depends_on:
      - web
    links:
      - "web:web"
    build: ./nginx
    ports:
      - 8080:80
    networks:
      net-django:
        ipv4_address: 10.127.2.2

networks:
  net-django:
    ipam:
      config:
        - subnet: 10.127.2.0/24

 (9)最后创建容器

docker-compose build
docker-compose up -d

 (10)容器创建启动后，登录x.x.x.x:8080即可
