以上两个问题按照如下顺序都能解决。亲测！！

1. 首先更新一下：yum -y update

2. centos8默认使用podman代替docker，所以需要containerd.io，那我们就安装一下就好了

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. 安装一些其他依赖

yum install -y yum-utils device-mapper-persistent-data lvm2
yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo

4. 安装docker

yum install -y docker-ce 

5. 启动docker

systemctl start docker

6. 使用docker命令
