elastic beanstalk docker nginx uwsgi django 在同一个容器中给出 502 bad gateway 错误

Question

我正在使用 nginx 和 uwsgi 在 elastic beanstalk 和 docker 中部署 django 应用程序。

以下是 Dockerfile：

FROM ubuntu:14.04

RUN mkdir -p /home/docker/src/server/logs/

EXPOSE  80

#Run command
cmd ["/home/docker/src/server/start.sh"]

但是当我尝试通过网络访问它时，我得到了502 Bad Gateway。

当我尝试 cURL Docker IP 时，出现了同样的错误。

Elastic Beanstalk 错误日志有以下错误：

[error] 29386#0: *1986 connect() failed (111: Connection refused) while connecting to upstream, client: 172.31.43.60, server: , request: "GET / HTTP/1.1", upstream: "http://[dockerip]:80/", host: "xxxxxxxxxxxxx.elasticbeanstalk.com"

这是我的 nginx 配置：

upstream django
{

 server unix:/tmp/api.sock; # for a file socket

}

server 
{

listen      80 default_server;

charset     utf-8;

# max upload size
client_max_body_size 4G;   # adjust to taste


location / {
    uwsgi_pass  django;
    include     /home/docker/src/server/uwsgi_params; # the uwsgi_params file you installed
}

sendfile off;
access_log /home/docker/src/server/logs/nginx-access.log;
error_log /home/docker/src/server/logs/nginx-error.log;

来自docker内部的uwsgi错误日志：

当前工作目录：/home/docker/src/server

检测到的二进制路径：/usr/local/bin/uwsgi

!!! 没有内部路由支持，使用 pcre 支持重建 !!!

uWSGI 以 root 身份运行，你可以使用 --uid/--gid/--chroot 选项

* 警告：你正在以 root 身份运行 uWSGI !!! (使用 --uid 标志) * chdir() 到 /home/docker/src/server/
