curl -fsSL https://download.docker.com/linux/debian/gpg | sudo apt-key add -
Ubuntu:
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
4、添加软件仓库(debian)
add-apt-repository \
"deb [arch=amd64] https://mirrors.tuna.tsinghua.edu.cn/docker-ce/linux/debian \
$(lsb_release -cs) \
stable"
Ubuntu:
add-apt-repository \
"deb [arch=amd64] https://mirrors.tuna.tsinghua.edu.cn/docker-ce/linux/ubuntu \
$(lsb_release -cs) \
stable"

3、配置docker的安装源
wget -O /etc/yum.repos.d/docker-ce.repo https://download.docker.com/linux/centos/docker-ce.repo
4、将安装源替换成清华源
sed -i 's+download.docker.com+mirrors.tuna.tsinghua.edu.cn/docker-ce+' /etc/yum.repos.d/docker-ce.repo

sudo systemctl start docker
sudo systemctl enable docker
