创建容器

sudo docker run -dit --name=Jenkins -p 8889:8080 -p 50000:50000 --restart=on-failure -v /home/user/jenkins:/var/jenkins_home 873436f3411b

进入容器

sudo docker exec -it b75729cdb52f /bin/bash

编辑文本发现咩有vi、vim、nano，于是执行安装vim命令提示没权限

jenkins@b75729cdb52f:/$ vi text.temp
bash: vi: command not found
jenkins@b75729cdb52f:/$ vim text.temp
bash: vim: command not found
jenkins@b75729cdb52f:/$ nano text.temp
bash: nano: command not found

jenkins@b75729cdb52f:/$ apt-get install vim
E: Could not open lock file /var/lib/dpkg/lock-frontend - open (13: Permission denied)
E: Unable to acquire the dpkg frontend lock (/var/lib/dpkg/lock-frontend), are you root?

重置root密码，提示不可以修改root密码

jenkins@b75729cdb52f:/$ passwd root
passwd: You may not view or modify password information for root.

查阅资料发现，docker进入容器可以以root身份进入（-u 0参数），退出当前容器重新进入

sudo docker exec -u 0 -it b75729cdb52f /bin/bash

这样进入就有root权限了

vim /etc/apt/sources.list
