Nginx不为我的Flask网站提供服务
问题内容：
我按照这个例子和这个关于stackoverflow的答案，我被困住了。
我正在Digitalocean VPS上运行此示例。我的文件结构如下：

Nginx的

nginx / 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 / sites-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 /静态
css/
js/
运行命令之后docker-compose up -d，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？
问题答案：
退后一步，单独运行Flask应用。
您有一些语法错误。
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)
然后放在一个Docker容器中，不带枪
FROM python:3.5
RUN mkdir /mainweb
COPY . /mainweb
WORKDIR /mainweb
RUN pip install -r requirements.txt
EXPOSE 5000
CMD ["python3","/mainweb/app.py"]
并运行它，看看它是否有效。
cd mainapp
docker build -t flask:test .
docker run --rm -p 5000:5000 flask:test
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-alpine
ADD 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
