【Docker】- CentOS8安装docker

sudo yum install -y yum-utils device-mapper-persistent-data lvm2

1、进入到 yum 的 repos 目录
cd /etc/yum.repos.d/

2、修改 centos 文件内容
sed -i 's/mirrorlist/#mirrorlist/g' /etc/yum.repos.d/CentOS-*
sed -i 's|#baseurl=http://mirror.centos.org|baseurl=http://vault.centos.org|g' /etc/yum.repos.d/CentOS-*

3、生成缓存更新
yum makecache

4、运行 yum update 并重新安装 vim
yum update -y
yum -y install vim

sudo yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo

yum install -y docker-ce docker-ce-cli containerd.io
