flask获取主机名镜像

屁眼脚本

cat <<END>host-web.py
import  socket
import datetime

from flask import Flask

app=Flask(__name__)

@app.route('/')
def hello():
    
    now_time = datetime.datetime.now()   
    hostname = socket.gethostname()
    ip = socket.gethostbyname(hostname)
    #return ip
    return hostname
    #return  now_time.strftime('%Y-%m-%d %H:%M:%S')

if __name__=='__main__':

    app.run(host='0.0.0.0',debug=True,port='8000')
END

docker镜像

cat <<END>Dockerfile
FROM alpine:latest

ENV TZ='Asia/Shanghai'
ENV TIMEZONE Asia/Shanghai
RUN echo "http://mirrors.aliyun.com/alpine/latest-stable/main/" > /etc/apk/repositories && \
    echo "http://mirrors.aliyun.com/alpine/latest-stable/community/" >> /etc/apk/repositories && \
    apk update && apk upgrade && \
    apk add tzdata bash-doc bash && \
    apk add python3-dev && \
    apk add py3-pip  && \
    pip3 install -i https://pypi.tuna.tsinghua.edu.cn/simple flask && \
    ln -snf /usr/share/zoneinfo/$TIMEZONE /etc/localtime && \
    echo $TIMEZONE > /etc/timezone 

ADD host-web.py .

EXPOSE 8000
ENTRYPOINT ["python3"]
CMD ["host-web.py"]
END

或者直接用的制作好的镜像
