gunicorn爲什麼會掛在這個配置？

我正在使用Docker構建一個多容器應用程序。一切都適用於Django（1.7）開發服務器。但是當我嘗試運行gunicorn時，命令gunicorn wsgi:application似乎開始，然後不提供輸出並保持對終端的控制，直到我點擊了Ctrl - C。這令人遺憾地意味着我沒有什麼有用的調試信息。gunicorn爲什麼會掛在這個配置？

我的API的Dockerfile是這樣的：

有興趣者還可以檢查出full project source 。任何人都知道這裏出了什麼問題？或者甚至我可以獲得更多有用的調試信息？

您可以運行另一個進程在容器中獲得更多的信息？（'docker exec -it /bin/bash' – 2015-02-09 22:12:09

@JavierCortejoso是的，我可以在容器中運行bash，這就是我試圖運行gunicorn的地方，讓我知道哪些信息可以幫助你，我會更新 – 2015-02-09 22:24:08

你能發佈你正在運行的'gunicorn'命令嗎？ – Alex 2015-02-10 00:07:06

使用帶有gunicorn的--bind國旗。

例子：

gunicorn wsgi:application --bind:0.0.0.0:80

gunicorn爲什麼會掛在這個配置？
