Docker的ubuntu镜像安装的容器无ifconfig和ping命令的解决

亲测可以解决但是再次运行ubuntu就不行了还需要重装,还未解决：
博主最近真的是天天踩坑：

[root@foundation38 tidb]# docker run -it --name vm1 ubuntu
root@6ac61d6d507e:/# ping vm1   ubuntu镜像没有ping和ip命令
bash: ping: command not found
root@6ac61d6d507e:/# ip addr 
bash: ip: command not found
root@6ac61d6d507e:/# exit
exit

[root@foundation38 tidb]# docker run -it --name vm2 ubuntu
root@a77e06da9b86:/# apt-get update
root@a77e06da9b86:/# apt install net-tools   安装ifconfig
root@a77e06da9b86:/# apt install iputils-ping  安装ping

测试：
