docker部署python（Dockerfile和docker-compose组合使用）

1. 开发python接口

from logging.handlers import TimedRotatingFileHandler
import tornado.ioloop
import tornado.web
import json
import logging


def init_log():
    log_file = 'demo.txt'
    logger = logging.getLogger()
    logger.setLevel(logging.DEBUG)
    fh = TimedRotatingFileHandler(log_file, when='D', interval=24, backupCount=7)
    datefmt = '%Y-%m-%d %H:%M:%S'
    format_str = '%(message)s'
    formatter = logging.Formatter(format_str, datefmt)
    fh.setFormatter(formatter)
    logger.addHandler(fh)
    return logger


class MainHandler(tornado.web.RequestHandler):

    def post(self):
        print("111111")
        body = self.request.body
        bodyRequest = json.loads(body)
        print(bodyRequest)
        body = {"mess": "MainHandler success"}
        self.write(json.dumps(body, ensure_ascii=False))


class MainHandler2(tornado.web.RequestHandler):

    def post(self):
        print("2222222")
        body = self.request.body
        bodyRequest = json.loads(body)
        print(bodyRequest)
        body = {"mess": "MainHandler2 success"}
        self.write(json.dumps(body, ensure_ascii=False))


class MainHandler3(tornado.web.RequestHandler):

    def post(self):
        print("3333333")
        body = self.request.body
        bodyRequest = json.loads(body)
        print(bodyRequest)
        body = {"mess": "MainHandler3 success"}
        self.write(json.dumps(body, ensure_ascii=False))


if __name__ == "__main__":
    application = tornado.web.Application([
        (r"/yicall/api/119423976/sessionCallBack", MainHandler),
        (r"/yicall/api/119423976/taskCallBack", MainHandler2),
        (r"/yicall/api/119423976/sessionQcCallBack", MainHandler3),
    ])
    application.listen(8888)
    tornado.ioloop.IOLoop.current().start()

2.生成requirements.txt文件

	pip freeze > requirements.txt

3. 创建Dockerfile文件

FROM python:3

ADD . /

RUN pip install -r requirements.txt

CMD [ "python", "./demo.py" ]

4. 创建docker-compose.yml文件

version: '3'
services:
  demo:
    image: python-interface:latest
    build: .
    ports:
      - 8888:8888
    volumes:
      - .:/code
    restart: always

5. image介绍

image: python-interface:latest 是 docker build -t python-interface . 生成的

image ：可以通过配置build . 生成镜像

build . : 加载的是当前目录的Dockerfile文件
