使用sudo docker-compose up

在docker进行查看  sudo docker run -it ubuntu bash

root@11f55a91272d:/# ifconfig -a

此时会出现报错,bash: ifconfig: command not found

因为每次进入docker都需要重新进行配置安装,docker是一个简单的容器

使用命令进行更新,root@11f55a91272d:/# apt update

然后还需要安装config 进行命令的查询 root@11f55a91272d:/# apt install net-tools

安装结束就可以进行查询了root@11f55a91272d:/# ifconfig -a
