centos8 安装docker19报错

今天在centos8上准备安装个docker，按照平常的安装方法，抛出了一个报错

[root@localhost ~]# yum install docker-ce
Extra Packages for Enterprise Linux 8 - x86_64                                                                                                                                                                              268 kB/s | 3.3 MB     00:12

在百度搜索了一下，发现是containerd.io-1.2.10-3.2.el7.x86_64 包版本不支持，而且官方也给出了解决方法

下载低版本的docker

yum install -y docker-ce --nobest

下载支持的containerd.io然后重新下载docker

wget https://download.docker.com/linux/centos/7/x86_64/edge/Packages/containerd.io-1.2.6-3.3.el7.x86_64.rpm
yum install -y  containerd.io-1.2.6-3.3.el7.x86_64.rpm 
yum install -y docker-ce

查看docker版本

docker -v
