Nginx不为我的Flask网站提供服务

退后一步，单独运行Flask应用。

您有一些语法错误。

from flask import Flask, render_templateapp=Flask(__name__)@app.route('/')def home():   # Remove double brackets    return render_template('home.html')  # The templates folder is already picked upif __name__=="__main__":    app.run(host="0.0.0.0", port=5000)

然后放在一个Docker容器中，不带q

FROM python:3.5RUN mkdir /mainwebCOPY . /mainwebWORKDIR /mainwebRUN pip install -r requirements.txtEXPOSE 5000CMD ["python3","/mainweb/app.py"]

并运行它，看看它是否有效。

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

开启http：// server：5000

然后从docker-compose仅使用该容器开始，并根据需要定义nginx。

nginx / Dockerfile

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

nginx / flask.conf（我根据项目中的文件进行了更改）

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。您不想让您的网站同时暴露5000和80（您不希望人们绕过Nginx），所以不要暴露5000
