国内服务器安装Docker

1.添加阿里云的GPG密钥

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

2.配置阿里云的Docker apt源

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

3.安装Docker

apt-get update
apt-get install docker-ce docker-ce-cli containerd.io

大功告成！
