Ubuntu_bionic安装docker：
sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"
加速：修改docker镜像源：
docker默认的源为国外官方源，下载速度较慢，可改为国内加速。
修改或新增 /etc/docker/daemon.json
{
"registry-mirrors": ["http://hub-mirror.c.163.com"]
}
systemctl restart docker.service
