Comment faire pour exécuter un conteneur python-flacon sur Mac OS?

Question

J'ai suivi un certain tutoriel en ligne Docker et moi avons écrit ce 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"] 

J'ai construit mon image avec: docker build -t ciasto/pythonflask:v1 .

qui a abouti à:

$ docker build -t ciasto/pythonflask:v1 .

macHost:pythonflask$ 

Quand je docker ps -a je reçois rien . Qu'ai-je fait de mal? Je ne reçois même pas d'erreur. Je suis sur Mac OS Sierra.

$ docker -v 
Docker version 1.13.1, build 092cba3

Pour afficher la liste de toutes les images créées avec docker, exécutez docker images. Il devrait montrer le nom de votre image que vous pouvez ensuite lancer avec docker run ciasto/pythonflask:v1.
