让python和基于组件的容器工作
我正在试图dockerize这个同构的应用程序的工作stream程。 我构build了下面的docker文件的容器。
FROM python:3.5-slim RUN apt-get update && \ apt-get -y install gcc mono-mcs && \ apt-get -y install vim && \ apt-get -y install nano && \ rm -rf /var/lib/apt/lists/* RUN mkdir -p /statics/js VOLUME ["/statics/"] WORKDIR /statics/js COPY requirements.txt /opt/requirements.txt RUN pip install -r /opt/requirements.txt EXPOSE 8080 CMD ["python", "/statics/js/app.py"] 这是结果：

所以我的第一个问题是第9步是什么意思？ 这是否意味着即使在运行容器之前，它正在尝试运行/statics/js/app.pypath，因为我不打算从host装入此statics卷。 其次，如果我运行命令：
$ docker run -it -v ~/Development/my-Docker-builds/pythonReact/statics/:/statics/ -d ciasto/pythonreact:v2
03d77c87651e752450e3be0aa64a0841c088b32a1db5424ad96c150c949d0366
我得到的哈希键，但没有任何工作！ 我甚至没有看到app.py的开始跟踪或错误消息有任何错误。
那么当我运行容器时，我应该如何从主机安装的卷运行app.py ？
您可以将CMD视为容器的启动脚本。 话虽如此，在第9步中，只有在启动容器时才会执行pyhton /statics/js/app.py标记。 此外，由于您使用的是-d标志，因此您将无法看到日志，因此您必须使用docker logs命令来获取它们，如下所示：
docker logs 03d77c87651e752450e3be0aa64a0841c088b32a1db5424ad96c150c949d0366
日志应该足以帮助你找出问题。 我希望它有帮助。
