docker打包Python程序

步驟：准備環境-復制Python程序-啟動程序

為了簡單，我們的Python程序就是一個Python文件app.py

app.py

from flask import Flask
app = Flask(__name__)
@app.route('/')
def hello():
    return "hello docker"
if __name__ == '__main__':
    app.run(host="0.0.0.0", port=5000)

Dockerfile

FROM python:2.7
LABEL maintainer="Peng Xiao<[e-mail]>"
RUN pip install flask
COPY app.py /app/
WORKDIR /app
EXPOSE 5000
CMD ["python", "app.py"]

build image 和 啟動容器

docker build -t soymilk/python-test .

docker run -d soymilk/python-test
