基于docker已安装的情况下，通过执行一下代码完成docker-compose的安装
sudo curl -L "https://github.com/docker/compose/releases/download/$(curl -s https://api.github.com/repos/docker/compose/releases/latest | grep '\"tag_name\":' | sed -E 's/.*\"([^\"]+)\".*/\1/')/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
sudo chmod +x /usr/local/bin/docker-compose最后查看一点docker-composer的版本
docker-compose -v
可以看到这里也是成功下载了此时的最新版本 v2.22.0
