1 移除旧版

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

2 设置repo

sudo apt-get install ca-certificates curl gnupg lsb-release

sudo mkdir -m 0755 -p /etc/apt/keyrings

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg

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

3 安装docker

sudo apt-get update

sudo apt-get install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin

4 添加当前用户权限

这步是可选的，你也可以都用sudo执行，就没这事了

# 将自己添加到docker组中
sudo groupadd docker
sudo gpasswd -a ${USER} docker

# 重启后重新load下权限
sudo service docker restart
newgrp - docker
