apt-get install apt-transport-https ca-certificates curl software-properties-common
curl -fsSL https://mirrors.aliyun.com/docker-ce/linux/ubuntu/gpg | sudo apt-key add -
apt-key fingerprint 0EBFCD88

apt-get update
apt-get -y install docker-ce
docker -v

systemctl daemon-reload
systemctl restart docker 
netstat -plnt
