Docker: Criando a Docker Image com o Python e Flask

echo 'from flask import Flask

app = Flask(__name__)

@app.route("/")
def hello():
    return "hello world!"

if __name__ == "__main__":
    app.run(host="0.0.0.0")' > app.py
 

Vamos pegar por exemplo o arquivo Dockerfile abaixo:

FROM python:3.6.1-alpine
RUN pip install flask
COPY app.py /app.py
CMD ["python","app.py"]
 

docker image build -t python-hello-world .

docker run -p 5001:5000 -d python-hello-world

http://localhost:5001
