使用Docker構建基於centos7鏡像的python環境

Dcokerfile配置信息

##############################################
# 基於centos7構建python3運行環境
# 構建命令: 在Dockerfile文件目錄下執行 docker build -t python-centos:3.5 .
# 容器啟動命令: docker run -itd --name python --restart always --privileged=true -v /root/dockers/python:/root/python -v /root/dockers/python/cron:/var/spool/cron python-centos:3.5 /usr/sbin/init
# 進入容器：docker exec -it python /bin/bash

使用方法

• dockerfile構建命令: 在Dockerfile文件目錄下執行 docker build -t python-centos:3.5 .
• 容器啟動命令: docker run -itd --name python --restart always --privileged=true -v /root/dockers/python:/root/python -v /root/dockers/python/cron:/var/spool/cron python-centos:3.5 /usr/sbin/init
