安装步骤：
1. 下载docker-ce的repo
curl https://download.docker.com/linux/centos/docker-ce.repo -o /etc/yum.repos.d/docker-ce.repo
2. 安装依赖（这是相比centos7的关键步骤）
yum install https://download.docker.com/linux/fedora/30/x86_64/stable/Packages/containerd.io-1.2.6-3.3.fc30.x86_64.rpm
3. 安装docker-ce
yum install docker-ce
4. 启动docker
systemctl start docker
5. 开机启动docker
systemctl enable docker
6.安装docker-compose
sudo curl -L "https://github.com/docker/compose/releases/download/1.25.5/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
7.添加操作权限
sudo chmod +x /usr/local/bin/docker-compose
8.设置快捷
sudo ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose
9.查看docker-compose 版本
docker-compose --version
