Question

大家好，新年快乐，

我在连接到我的bluemix容器时遇到了一些问题，我跟着这个IBM's Bluemix guide 学习如何将docker镜像拉到bluemix图像库，它可以工作。

然后我执行命令打开端口9080服务器端（根据我的Dockerfile，vm为5000）

PS :(（我尝试使用-P而不是-p 9080或-p 9080：5000，但没有解决此问题））

cf ic -v run -d -p 9080 --name testdebug registry.ng.bluemix.net/datainjector/esolom python testGUI.py

在“cf ic ps”之后，我获得了：

CONTAINER ID      IMAGE       
8457d4bb-247      registry.ng.bluemix.net/datainjector/esolom:latest 

COMMAND                 PORTS          NAMES  
"python testGUI.py "    9080/tcp      testdebug

debug命令（在运行图像时执行）报告给我：

接下来，我将请求的IP绑定到：

cf ic ip request // 169.46.18.243 was given
cf ic ip bind 169.46.18.243 testdebug
OK
The IP address was bound successfully.

“cf ic ps”命令给了我这个：

CONTAINER ID        IMAGE

PORTS                          NAMES

那么，是否将相同的端口归因于主机和VM负责调试日志中的“connection：close”？或者是那两个不同的问题？

“connection：close”是否说明我无法连接到网络应用程序？

你知道如何解决这个问题吗？（要在图像中修复某些内容？还是在CLI中添加其他选项？）

感谢您的阅读，您的承诺以及您的答案！

PS：线索：我正在寻找修改Dockerfile，我读到我必须有2条指令才能将我的docker镜像集成到Bluemix，这是一个睡眠命令，所以我确定容器在调用之前已经启动了，显然是“ENV PORT 3000”指令，这里是我的Dockerfile，不要犹豫复习它，容易发生简单的错误。

FROM ubuntu:14.04
RUN apt-get update && apt-get -y install python2.7
RUN apt-get -y install python-pip
RUN pip install Flask
RUN pip install ibmiotf
RUN pip install requests
RUN pip install flask-socketio
RUN pip install cloudant
ENV PORT=3000
EXPOSE 3000
ADD ./SIARA /opt/SIARA/
WORKDIR /opt/SIARA/
CMD (sleep 60)
CMD ["python", "testGUI.py"]

Answer 1

将Dockerfile更改为：

CMD sleep 60 && python testGUI.py

看到@gile评论后。

即使它没有立即起作用，但在3小时后效果出奇的好！

编辑：似乎这只是一个幸运的镜头，我无法再次访问容器，我的想法是它工作，因为我的dockerHub在提交Dockerfile上的更改后重建了图像因为它在我之后工作将图像从dockerhub repo复制到bluemix private repo。

是否突出了问题？因为我不明白为什么它再也没有起作用......

无法连接到我的Bluemix容器（连接：关闭）
