一、拉取Python3.6.4 镜像

docker pull python:3.6.4

二、宿主机创建testflask目录，并添加文件

touch app.py docker-compose.yml Dockerfile gunicorn.conf.py requirements.txt

app.py

from flask import Flask

app = Flask(__name__)

@app.route('/')
def hello():
    return 'Hello World! I have been seen {} times.\n'.format(1)

if __name__ == "__main__":
    app.run(debug=True)

docker-compose.yml

version: '2'
services:
  flaskweb:
    build: .
    volumes:
      - .:/code  # 把当前目录映射到docker容器的/code 目录下
    ports:
      - 8888:8888

Dockerfile

FROM python:3.6.4
ADD . /code
WORKDIR /code
RUN pip install -r requirements.txt
CMD ["gunicorn","app:app","-c","./gunicorn.conf.py"]

requirements.txt

flask
gunicorn
gevent

三、运行：

docker-compose up --build

访问http://IP:8888

四、配置nginx

在https://www.jianshu.com/p/4c57fcd0b9e3的基础上修改
docker-compose.yml

version: '2'
services:
  nginx:
    image: nginx:latest
    restart: always
    container_name: nginx
    volumes:
      - /opt/nginx/conf/nginx.conf:/etc/nginx/conf/nginx.conf
      - /opt/nginx/conf.d:/etc/nginx/conf.d
      - /opt/nginx/html:/usr/share/nginx/html
      - /opt/nginx/logs/nginx:/var/log/nginx
    ports:
      - 8887:8887

conf.d/default.conf

server {
    listen       8887;
    server_name  192.168.56.102;

    # rewrite ^(.*)$  https://www.vhxsl.com permanent;

    location / {
        include uwsgi_params;
        add_header Access-Control-Allow-Origin *;

        proxy_read_timeout 3600s;
        proxy_redirect off;
        proxy_http_version 1.1;
        #proxy_pass_header Server;

        proxy_set_header Host $http_host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Scheme $scheme;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
        proxy_pass http://192.168.56.102:8888; #gunicorn IP 
    }

    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
        root   /usr/share/nginx/html;
    }
}

最后rebuild nginx容器
访问http://IP:8887
