一、卸载

卸载docker

sudo apt-get remove docker docker-engine docker.io containerd runc

删除相关依赖

sudo apt-get purge docker-buildx-plugin docker-ce docker-ce-cli docker-compose-plugin nvidia-docker2

自动移除不需要的依赖

sudo apt-get autoremove

清理残留配置文件

sudo rm -rf /etc/docker
sudo rm -rf /etc/default/docker
sudo rm -rf /etc/systemd/system/docker.service
sudo rm -rf /etc/systemd/system/docker.socket
sudo rm -rf /usr/lib/systemd/system/docker.service
sudo rm -rf /usr/lib/systemd/system/docker.socket

检查是否有相关包

dpkg -l | grep docker

二、安装

安装必要证书

sudo apt install apt-transport-https ca-certificates curl software-properties-common gnupg lsb-release

添加阿里GPG密钥

curl -fsSL https://mirrors.aliyun.com/docker-ce/linux/ubuntu/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg

添加阿里apt源

echo "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://mirrors.aliyun.com/docker-ce/linux/ubuntu $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

更新源

sudo apt update 
sudo apt-get update

安装docker

sudo apt install docker-ce docker-ce-cli containerd.io

查看Docker版本

sudo docker version

设置开机启动
