目前国内服务器厂商已经不能正常访问：download.docker.com 域名，也就无法安装 docker 服务。
报错：

也可使用腾讯云镜像：https://mirrors.cloud.tencent.com/docker-ce/linux/debian/gpg
添加 Docker 仓库
# Add Docker's official 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/debian/gpg -o /etc/apt/keyrings/docker.asc
sudo curl -fsSL https://mirrors.aliyun.com/docker-ce/linux/debian/gpg -o /etc/apt/keyrings/docker.asc
sudo chmod a+r /etc/apt/keyrings/docker.asc
# Add the repository to Apt sources:
echo \
"deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.asc] https://mirrors.aliyun.com/docker-ce/linux/debian \

sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
sudo apt-get update安装
sudo apt-get install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin运行 hello-world
sudo docker run hello-world配置镜像加速源
阿里云
针对Docker客户端版本大于 1.10.0 的用户
您可以通过修改daemon配置文件/etc/docker/daemon.json来使用加速器
注意：putyoumirror 替换成自己的。
sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'EOF'
{
"registry-mirrors": ["https://putyoumirror.mirror.aliyuncs.com"]
}
EOF
sudo systemctl daemon-reload
sudo systemctl restart docker腾讯云
registry-mirrors 更改腾讯的源即可
{
"registry-mirrors": [
"https://mirror.ccs.tencentyun.com"
]
}
