安装docker

#卸载老版本docker
sudo apt-get remove docker docker-engine docker.io containerd runc
 
#更新软件包索引，并且安装docker依赖
sudo apt update
sudo apt-get install ca-certificates curl gnupg lsb-release
 
#添加docker密钥
curl -fsSL http://mirrors.aliyun.com/docker-ce/linux/ubuntu/gpg | sudo apt-key add -
 
#添加阿里云docker软件源
sudo add-apt-repository "deb [arch=amd64] http://mirrors.aliyun.com/docker-ce/linux/ubuntu $(lsb_release -cs) stable"
 
#安装docker
sudo apt-get install docker-ce docker-ce-cli containerd.i
 
#配置用户组(非必须操作，此操作目的是为了以后执行docker命令时无需输入sudo密码，避免这些重复操作而已。)
sudo usermod -aG docker $USER
sudo reboot
 
#等待重启后，检验docker是否安装成功
service start docker
sudo apt-get -y install apt-transport-https ca-certificates curl software-properties-common
service docker restart
sudo docker run hello-world
 

卸载docker

#删除docker的所有包
apt-get autoremove docker docker-ce docker-engine  docker.io  containerd runc
 
#查看docker是否卸载干净
dpkg -l | grep docker
dpkg -l |grep ^rc|awk '{print $2}' |sudo xargs dpkg -P
 
#删除相关插件
apt-get autoremove docker-ce-*
 
#删除docker配置目录
rm -rf /etc/systemd/system/docker.service.d
rm -rf /var/lib/docker
 
#确定docker卸载完毕
docker --version
 
#遇到的问题
#按照上述流程后，再次输入docker --version还是会出现docker的版本号，让我很纳闷。输入which docker后，发现还存在一个snap 版本的docker，输入以下命令删除
which docker
sudo snap remove --purge docker
 
#再输入
whereis docker
将所有与docker相关的文件删除。
