前阵子朋友圈刷到了 CentOS 8 发布的消息，Esxi 尝尝鲜，安装过程一如既往，熟悉的味道，没发觉什么不一样的地方，也可能是选择了最小化安装的原因吧。

因为需要跑几个 docker 服务，所以依照官方说明几行命令下来，然后就报错了：

# yum install docker-ce
Last metadata expiration check: 0:01:25 ago on Mon 28 Oct 2019 02:22:35 AM CST.
Error:

看起来是 containers.io 这个包还没提供 CentOS 8 的版本，网上查了一下已经有解决方法了，CentOS 8 install Docker 。
