gunicorn为什么会挂在这个configuration？
我正在使用Docker构build一个多容器应用程序。 一切正常与Django（1.7）开发服务器。 但是当我尝试运行gunicorn时， gunicorn wsgi:application的命令似乎开始，然后提供没有输出，并保持terminal的控制，直到我按Ctrl – C。 这令人遗憾地意味着我没有什么有用的debugging信息。
我的API的Dockerfile是这样的：
FROM ubuntu:14.04 MAINTAINER Garry Cairns ENV REFRESHED_AT 2015-01-13 # update packages and prepare to build software RUN ["apt-get", "update"] RUN ["apt-get", "-y", "install", "build-essential", "vim", "git", "curl"] RUN ["locale-gen", "en_GB.UTF-8"] # install latest python RUN ["apt-get", "-y", "build-dep", "python3-dev", "python3-imaging"] RUN ["apt-get", "-y", "install", "python3-dev", "python3-imaging", "python3-pip"] # prepare postgreSQL support RUN ["apt-get", "-y", "build-dep", "python3-psycopg2"] # create a python user to run our programs RUN ["groupadd", "-r", "python"] RUN ["useradd", "-r", "-g", "python", "python"] WORKDIR /home/python ADD ./ /home/python # manage requirements ENV REQUIREMENTS_REFRESHED_AT 2015-02-09 RUN ["pip3", "install", "-r", "requirements.txt"]
我的产品设置（一般来说，cookiecutter Django的默认设置）是这样的：

用gunicorn使用--bind标志。
例：
gunicorn wsgi:application --bind:0.0.0.0:80
