我正在关注这个example和answer on stackoverflow,我被困住了.
我在digitalocean VPS上运行此示例.我的文件结构如下：

项目结构

      README

泊坞窗,compose.yml

version: '2'
services:
    app:
        restart: always
        build: ./mainweb
        command: gunicorn -w 2 -b :5000 wsgi:app
        networks:

        expose:
            - "5000"
        ports:

        expose:

  wsgi.py

mainweb / app.py

from flask import Flask, render_template

app=Flask(__name__)

@app.route('/')
def home()():
    return render_template('templates/home.html')


if __name__=="__main__":
    app.run(host="0.0.0.0", port=5000)

mainweb / Dockerfile

FROM python:3.5
MAINTAINER castellanprime

RUN mkdir /mainweb
COPY . /mainweb
WORKDIR /mainweb
RUN pip install -r requirements.txt

mainweb /模板/

   home.html

mainweb /模板/ home.html做为

<!doctype html>
<html>
<head>
    <title> My website </title>
</head>
<body>
    <h1> I am here </h1>
</body>
</html>

mainweb / wsgi.py

from app import app

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

nginx的

   Dockerfile
   sites-enabled.conf
   static/

nginx的/ Dockerfile

FROM nginx:1.13.1-alpine
MAINTAINER castellanprime
ADD sites-enabled.conf /etc/nginx/conf.d/sites-enabled.conf
ADD static/ /www/static/

nginx的/网站,enabled.conf

server{

    listen 8080;
    server_name app;  #  Should I put my actual www.XXXXXX.XXXXX address here
    charset utf-8;

    location /static{
        alias /www/static/;
    }

    location / {
        proxy_pass http://app:5000;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X_Forwared-For $proxy_add_x_forwarded_for;
    }
}

nginx的/静

   css/
   js/

运行命令docker-compose up -d后,我从另一个系统上的另一个Web客户端检查www.XXXXXX.com:8880或www.XXXXXX.com:8080.
我得到了标准的nginx网页.

如何将其重定向到home.html？

解决方法:

退后一步,单独运行Flask应用程序.

你有一些语法错误.

from flask import Flask, render_template

app=Flask(__name__)

@app.route('/')
def home():   # Remove double brackets
    return render_template('home.html')  # The templates folder is already picked up

if __name__=="__main__":
    app.run(host="0.0.0.0", port=5000)

然后在Docker容器中,没有gunicorn

FROM python:3.5

RUN mkdir /mainweb
COPY . /mainweb
WORKDIR /mainweb
RUN pip install -r requirements.txt
EXPOSE 5000
CMD ["python3","/mainweb/app.py"]

运行它,看它是否有效.

cd mainapp
docker build -t flask:test .
docker run --rm -p 5000:5000 flask:test

打开http://server:5000

然后从docker-compose开始只使用该容器并根据需要定义nginx.

nginx的/ Dockerfile

FROM nginx:1.13.1-alpine
ADD flask.conf /etc/nginx/conf.d/
EXPOSE 8080

nginx / flask.conf(我根据项目中的文件改变了这个)

server {

    listen 8080;    # This is the port to EXPOSE in nginx container
    server_name app;  # You can change this, but not necessary
    charset utf-8;

    location ^~ /static/ {
        alias /usr/share/nginx/html/; 
    }

    location / {
        try_files $uri $uri/ @flask;
    }

    location @flask {
        proxy_pass http://app:5000;   # This is the port Flask container EXPOSE'd
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X_Forwared-For $proxy_add_x_forwarded_for;
    }
}

最后,撰写.您不希望您的网站暴露5000和80(您不希望人们绕过nginx),所以只是不要暴露5000

version: '2'

        restart: always

        volumes:
            - ./mainweb/static:/usr/share/nginx/html
        ports:
