Doker提供的ubuntu鏡像非常干凈，大小只有63.1MB，沒有常見的一些基本庫。

進(jìn)入ubuntu容器中查找不到ifconfig，ping，vim等基本命令。

test01@test:~$ docker run -it --name version1 ubuntu:18.04 /bin/bash

root@e63d89aab255:/# ifconfig

bash: ifconfig: command not found

root@e63d89aab255:/# ping www.baidu.com

bash: ping: command not found

root@e63d89aab255:/# ^C

root@e63d89aab255:/# vim

bash: vim: command not found

root@e63d89aab255:/#

通過apt-get命令進(jìn)行安裝。

root@e63d89aab255:/# apt-get update

root@e63d89aab255:/# apt install net-tools 安裝ifconfig

root@e63d89aab255:/# apt install iputils-ping 安裝ping

【注】：

net-tools包含：arp, ifconfig, netstat, rarp , nameif, route這幾個(gè)工具。
