本文详细记录了在Centos8环境下从零开始部署k8s单机集群的过程，包括解决podman与docker冲突、配置国内镜像、安装与配置docker及k8s组件、初始化集群、安装网络插件flannel等关键步骤。

趁着春节体验了把Centos8，用着感觉和7没有太大变化，由于重新安装了Centos8，以前配置的k8s环境要重新配置了，在Centos8上配置docker和k8s遇到了不少坑，记录一下部署过程。

卸载podman，centos8默认安装了podman容器，它和docker有冲突需要卸载掉

yum delete podman

配置yum国内镜像

vim /etc/hostname 修改主机名k8sserver

关闭防火墙

systemctl disable firewalld

systemctl stop firewalld

关闭selinux

vim /etc/selinux/config 如下

# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
#     enforcing - SELinux security policy is enforced.
#     permissive - SELinux prints warnings instead of enforcing.
#     disabled - No SELinux policy is loaded.
SELINUX=disabled
# SELINUXTYPE= can take one of these three values:
#     targeted - Targeted processes are protected,
#     minimum - Modification of targeted policy. O
