部署 Flask 应用

当前目录是get-pip，目录结构如下：

$ tree ..├── app.py├── Dockerfile├── README.md└── requirements.txt

app.py：

requirements.txt：

Flaskrequests

Dockerfile：

FROM python:3.7LABEL maintainer="michael"ENV LANG C.UTF-8COPY . /appCOPY ./.pip/pip.conf ~/.pip/pip.confWORKDIR /appRUN pip install -r requirements.txt --proxy="http://127.0.0.1:3128"ENTRYPOINT ["python"]CMD ["app.py"]

在get-pip目录下，构建镜像：

docker build -t registry.domain.com/michael/get-ip:latest .

推送镜像：

docker login -u micahel registry.domain.comdocker push registry.domain.com/michael/get-ip:latest

因为网络的原因，无法直接连接 pypi 官方源，所以，在 pip install 时，使用了 --proxy 参数来指定代理。
