k8s

    • 环境初始化
    • 安装Harbor
    • 安装k8s
    • 安装istio和kubevirt

使用脚本部署k8s1.25版本平台，网络插件使用flannel ，容器运行时ctr，部署包括harbor仓库，服务网格、kubevirt服务等

使用的centos7.9资源配置如下：

主机IP资源
master192.168.200.1004C_8G_100G
node192.168.200.1014C_8G_100G

环境初始化

两边节点修改主机名

hostnamectl set-hostname master

hostnamectl set-hostname node

cat >> /etc/hosts <<eof
192.168.200.100 master
192.168.200.101 node
eof

mastr节点配置centos源

mkdir /opt/centos

mount /dev/sr0 //opt/centos/

rm -rf /etc/yum.repos.d/*

配置repo仓库

vi /etc/yum.repos.d/local.repo

gpgcheck=0
enabled=1
baseurl=file:///opt/centos
[k8s]
name=k8s
