docker-compose搭建flask环境:python3-flask-uwsgi-nginx-supervisor

话说想把之前的flask项目搬家,之前是手动部署。现在直接用docker-compose简单粗暴,一键部署。

先看下目录结构

├── docker-compose.yml
├── flask
│   └── Dockerfile	#我的项目是python3，就安装python3。以及uwsgi和supervisor
├── log 	#存放日志文件
├── nginx
│   ├── default.conf   # 为了跟uwsgi沟通
│   └── nginx.conf		#改了nginx启动权限root(为了简单测试,等有时间再弄个文章)和daemon off
├── README.md
├── tmp	#存访uwsgi.sock
└── wwwroot #flask项目目录
    ├── app						#项目工程
    │   ├── __init__.py
    ├── manage.py				#项目启动文件
    ├── requirements.txt   		#项目需要的的包
    ├── supervisord.conf		#supervisor配置文件
    └── uwsgi.ini			    #uwsgi配置文件

from flask import Flask

app = Flask(__name__)


@app.route("/")
def index():
    return "uwsgi nginx flask!"

使用方法:

docker-compose build
docker-compose up -d
