1. 新建gunicorn_config文件

• gunicorn_config.py

# 并行工作进程数
workers = 2
# 指定每个工作者的线程数
threads = 4
# 监听内网端口
bind = '0.0.0.0:5000'
# 工作模式协程
worker_class = 'gevent'
# 设置最大并发量
worker_connections = 2000

import os
if not os.path.exists('./log/'):
    os.mkdir('./log/')
# 设置进程文件目录
pidfile = './log/gunicorn.pid'
# 设置访问日志和错误信息日志路径
accesslog = './log/gunicorn_acess.log'
errorlog  = './log/gunicorn_error.log'
# 设置日志记录水平
loglevel = 'info'
# 代码发生变化是否自动重启
reload=True

2. 新建Dockerfile文件

• Dockerfile:

FROM python:3.7-alpine
MAINTAINER "Silly<Silly@Silly.com>"
WORKDIR /home/project

RUN echo http://mirrors.aliyun.com/alpine/v3.9/main > /etc/apk/repositories
RUN echo http://mirrors.aliyun.com/alpine/v3.9/community >> /etc/apk/repositorie

RUN apk update
RUN apk --update add --no-cache gcc
RUN apk --update add --no-cache g++
RUN apk --update add --no-cache libffi-dev openssl-dev

COPY requirements.txt requirements.txt
RUN pip install --no-cache-dir -r requirements.txt -i https://pypi.tuna.tsinghua.edu.cn/simple

CMD gunicorn -c gunicorn_config.py main:app

3. 构建镜像->新增容器->启动 有两种方式:

构建docker镜像:

docker build . -t xiao_demo1:latest

创建并启动容器:

docker run --name xiao_demo1 -p hostPort:containerPort -v /home/xiao_demo:/home/project -itd xiao_demo:latest sh

用docker-compose构建镜像,创建并启动容器:

• docker-compose.yaml

version: "3.0"
services:
    xiao:
        image: xiao_demo:latest
        build: .
        container_name: xiao_demo1
        restart: always
        volumes:
          - ./:/home/project
        ports:
            - "5000:5000"
#    networks:
#      xiao_net:
#        aliases:
#          - xiao-pc
#networks:
#    xiao_net:
#        name: xiao_net

命令行执行

docker-compose up -d

创建并启动ngxin容器

docker run --name nginx -v `pwd`/logs:/var/log/nginx -v `pwd`/conf.d:/etc/nginx/conf.d -v `pwd`/html:/usr/share/nginx/html --net host -p 80:80 -itd --restart=always nginx /bin/bash

在conf.d目录下新建default.conf (nginx配置文件)

server {
    listen 80;
    server_name xx.xxx.xxx.xxx; # 这是HOST机器的外部域名，用地址也行
 
    location / {
        proxy_pass http://127.0.0.1:5000; # 这里是指向 gunicorn host 的服务地址
        proxy_set_header Host $host;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    }
}
