如何在Mac OS上运行python-flask容器？
我遵循一些在线Docker教程，我写了这个Dockerfile ：
FROM python:3.5-slim WORKDIR /opt COPY requirements.txt /opt/requirements.txt RUN pip install -r /opt/requirements.txt COPY hello.py /opt/hello.py EXPOSE 5000 CMD ["python", "/opt/hello.py"]
我build立了我的形象： docker build -t ciasto/pythonflask:v1 .
导致：
$ docker build -t ciasto/pythonflask:v1 .

当我做docker ps -a我什么也得不到。 我做错了什么？ 我甚至没有得到任何错误。 我在Mac OS Sierra上。
$ docker -v Docker version 1.13.1, build 092cba3
要使用docker查看所有构build的图像的列表，请运行docker images 。 它应该显示你的图像的名字，然后你可以docker run ciasto/pythonflask:v1 。
