Django欢迎页面上的docker-compose错误

时间：2017-04-09 22:13:16

标签： django windows docker docker-compose boot2docker

当我访问地址http://192.168.99.100:8000/时，我无法在浏览器中看到django的欢迎页面。

public ActionResult Multiple() 
{ 
    if(DateTime.Now.Day % 2 == 0)     
    { 
         return View("Other"); } 
    else 
    {
       return RedirectToAction("Index"); 
    } 
}

还有另一种方式（或localhost链接）我可以访问我的django的欢迎页面吗？

目前尚不清楚具体是什么，但要到达Docker的已发布端口，您需要做一些事情：

  1. 端口本身需要在docker主机上推送。要将主机上的端口8888映射到容器内的端口8000，通常使用docker run -p 8888:8000 ...，或者在docker-compose.yml中将您的服务下的部分映射到：

    2. ports: - 8888:8000

    1. 容器应用程序本身需要侦听容器端口上的所有接口（0.0.0.0）（本例中为8000）。

    2. 您需要连接到已发布端口上的docker主机。使用docker-machine，IP将是VM的IP。您可以使用docker-machine ip查找docker主机的IP，或者在任何环境中echo $DOCKER_HOST都会告诉您Docker命令的发送位置。

      3. 你已经完成了第1部分和第3部分。容器本身正在监听所有接口，但是从粘贴的各种命令中，我怀疑服务本身并没有一直启动（可能是因为你做了一个数据库docker-compose run web在某一时刻，而不是docker-compose up），因为有一个输出部分没有服务运行线。也许你在检查网页之前用 cont + C 关闭服务。

Dockerfile writes this try:

FROM python:2.7
ENV PYTHONUNBUFFERED 1
RUN mkdir /code
WORKDIR /code
ADD requirements.txt /code/
RUN pip install -r requirements.txt
ADD . /code/
RUN python manage.py migrate
RUN python manage.py runserver

del command: python manage.py runserver 0.0.0.0:8000

Try changing a port.

This is my opinion, hope to help you
