1、目录结构如下
# tree devops_docker/ -L 2
devops_docker/
├── devops // 代码目录
│ ├── assets
│ ├── collected_static // Django项目收集的静态文件目录
│ ├── devops
│ ├── manage.py
│ ├── requirements.txt
│ ├── scripts
│ ├── static
│ └── templates
├── docker-compose.yml // docker-compose 文件
├── Dockerfile // docker 容器文件
└── nginx_config
└── nginx.conf // nginx 配置文件
2、编写 devops_docker/Dockerfile，配置 Django 环境，打包项目代码，安装项目依赖，修改 settings.py 配置
# cat devops_docker/Dockerfile
FROM python:2
RUN mkdir /code
WORKDIR /code
ADD devops/ /code/
RUN pip install -i https://pypi.tuna.tsinghua.edu.cn/simple some-package -r requirements.txt
RUN sed -i 's/DEBUG = True/DEBUG = False/' devops/settings.py
3、配置 nginx.conf，代理后端 Django 项目
# cat devops_docker/nginx_config/nginx.conf
server {
listen 8888;
server_name _;
# Load configuration files for the default server block.
include /etc/nginx/default.d/*.conf;
location /static {
alias /devops/static/;
}
location / {
# if ($request_uri = "/") {
# rewrite "/" http://10.1.2.101:8888/assets/ break;
# }
proxy_set_header Host $host;
proxy_pass http://web:9999;
}
}
4、配置 docker-compose 文件，编排后端 Django 项目和 nginx 服务
# cat devops_docker/docker-compose.yml
version: '2'
services:
web:
build: .
command: gunicorn -w 5 --timeout 60 -b 0.0.0.0:9999 devops.wsgi
expose:
- "9999"
nginx:
image: nginx:latest
ports:
- "8888:8888"
volumes:
- ./devops/collected_static:/devops/static
- ./nginx_config:/etc/nginx/conf.d
depends_on:
- web
5、启动服务
# docker-compose up -d
