502 Docker Flask应用程序的带有Nginx反向代理的坏网关

这是我的文件

RUN adduser -D marty
# current directory where the app will be installed
WORKDIR /home/marty
# copy file from the machine to the container file system
COPY app app
COPY requirements.txt requirements.txt
# run a virtual env and install requirements
RUN python3 -m venv venv
CMD source ./venv/bin/activate

# The EXPOSE instruction indicates the ports on which a container # # will listen for connections
# Since Flask apps listen to port 5000 by default, we expose it
EXPOSE 5000
# Run app.py when the container launches
CMD python app/app.py
最后,这里是我的nginx配置
server {
listen 80;
server_name api.example.com;
location / {
return 301 https://$host$request_uri;
}
location /.well-known/acme-challenge/ {
root /var/www/certbot;
}
}
server {
listen 443 ssl;
server_name api.example.com;
location / {
proxy_pass http://0.0.0.0:5000;
}
ssl_certificate /etc/letsencrypt/live/api.example.com/fullchain.pem;
ssl_certificate_key /etc/letsencrypt/live/api.example.com/privkey.pem;
include /etc/letsencrypt/options-ssl-nginx.conf;
ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem;
}
由于某种原因,当导航到api.example.com时,我总是得到一个502坏网关
我还为api创建了一个记录。及www.api
问题在于Centos 7和Selinux。我通过切换到Debian并发誓永远退出Centos解决了这个问题。也有同样的问题,并且
setEnforce0
启用了请求。我不会在这里责备任何人,当然也不会责备CentOS;这正是使用selinux设置nginx的方式(不允许轻松打开443和80以外的端口)。谢谢你的建议!我的配置与Debian完全相同,但在Debian上运行,但仍然存在以下错误:/
