centos 配置docker

参照官方教程执行

https://docs.docker.com/engine/install/centos/

1、当执行到下面的命令时，注意替换规则

sudo yum install docker-ce-<VERSION_STRING> docker-ce-cli-<VERSION_STRING> containerd.io docker-compose-plugin
sudo yum install docker-ce-18.09.1 docker-ce-cli-18.09.1 containerd.io docker-compose-plugin

2、docker compose 安装

sudo curl -L "https://github.com/docker/compose/releases/download/1.23.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
sudo chmod +x /usr/local/bin/docker-compose
docker compose --version

3、如果要执行docker compose的相关命令，不要用docker-compose.
