CentOS 8 系统中如果没有安装Podman的话，想要离线安装会比较麻烦，因为podman依赖的包比较多，从网上一个一个下载会很繁琐 ， 也容易出错 。这里介绍一种曲线救国的方式来离线安装 。
首先分享下我刚获取的离线安装包，下载，解压后，直接安装所有rpm 就可以了 。链接：https://pan.baidu.com/s/1AKrGVDNln1zSNpsD74HQrg提取码：6666
[root@node13 podmanpackage]# podman -vpodman version 3.3.1【CentOS 8 离线安装 podman 解决方法】之所以叫曲线救国，多少是有点儿原因的：离线安装包的制作方法，很简单，就是用一台能够联网的centos8 机器，然后执行下面的命令yum install --downloadonly --downloaddir=/opt/podmanpackage/ podman就会把所有的包下载到 /opt/podmanpackage/ 这个目录下，然后把这个目录下的所有rpm 打包到离线的机器上进行安装，就可以了，是不是有点儿曲线救国的意思 。
下面是操作日志：
