Docker小工具

原由

• 由于最近程序选封装成docker,后需要查看日志和进入和重启容器,需要知道dockerID 或者容器名称，还需要鼠标记录复制，避免麻烦，才触发该脚本

源代码

• 代码

#!/usr/bin/python3
# -*- coding:utf-8 -*-
import docker,os

client = docker.from_env()
# client = docker.DockerClient("http://127.0.0.1:2375")

    docker_index += 1

使用

• 自行把该脚本封装成二进制文件然后上传到需要使用的服务器的/usr/sbin下面
• 需要使用root用户进行运行，进入和删除容器需要root用户

[root@abchina ~]# SelectDocker 
Please use the root user
Current Docker Container Running List: 
=========================================================
docker index: 0   mysql-test
=========================================================
Please enter the required operation options:
1、restart docker
2、get into docker
3、tailf docker log
=========================================================

Please enter the Docker index number to enter the Docker
