卸载旧版本

for pkg in docker.io docker-doc docker-compose docker-compose-v2 podman-docker containerd runc; do sudo apt-get remove $pkg; done
安装
1）设置 Docker 的apt存储库
1.1）添加 docker 官方的 GPG key
sudo apt-get update sudo apt-get install ca-certificates curl sudo install -m 0755 -d /etc/apt/keyrings sudo curl -fsSL https://download.docker.com/linux/ubuntu/gpg -o /etc/apt/keyrings/docker.asc sudo chmod a+r /etc/apt/keyrings/docker.asc
1.2）将 Docker 的官方仓库地址写入到系统的 APT 源列表文件中
echo \ "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.asc] https://download.docker.com/linux/ubuntu \ $(. /etc/os-release && echo "${UBUNTU_CODENAME:-$VERSION_CODENAME}") stable" | \ sudo tee /etc/apt/sources.list.d/docker.list > /dev/null sudo apt-get update
2）安装 Docker 包
sudo apt-get install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin
配置镜像源加速
1）打开网址并登录
网址：https://cr.console.aliyun.com/cn-shanghai/instances/mirrors
2）执行代码
忘了之前是不是要开通的
3）添加 1panel 的镜像源
vim /etc/docker/daemon.json
第一条是阿里云的镜像加速，不用改，添加第二条 https://docker.1panel.live
{ "registry-mirrors": [ "https://xxxx.com", "https://docker.1panel.live" ] }
测试是否安装成功
sudo docker run hello-world
