Question

我试图与dokku交朋友。我在DigitalOcean Droplet上运行dokku。

user@mypc:~$ cat Procfile 
web: python3 main.py

user@mypc:~$ git push dokku master

To dokku@myapp.ru:app
   d2cd6b3..7733adf  master -> master

尽管下载成功，但我仍然收到502错误

root@myserver:~# dokku run app ps aux

root@myserver:~# dokku logs app
[I 140324 08:41:37 main:75] Starting http server on localhost:5000

如果直接运行应用程序，它会成功启动，但我仍会收到502错误。

root@myserver:~# dokku run app python3 main.py
[I 140324 08:59:19 main:75] Starting http server on localhost:5000

所有环境变量拼写正确，等等，因为应用程序正在运行。有什么想法吗？

Answer 1

比我想象的容易得多。我绑定了0.0.0.0

抱歉愚蠢的问题。

Answer 2

我遇到了同样的问题。绑定到0.0.0.0是问题的一部分。 Dokku也期待Tornado在5000端口上运行。所以，修复程序正在改变服务器监听呼叫：http_server.listen（5000，address =＆＃39; 0.0.0.0＆＃39;）

Dokku + tornado app = 502 Bad Gateway
