ansible的那个也是可以的 拿来改一下
这脚本是在 centos7.x上跑的 我再加个 debian 11的
kuboard提供的脚本
pre
有空改一下为 debian11的
从这里开始 Auguest first monday
先做一个 centos7.8的模板 qm clone 116 118 --name k8s-node1-centos7.8 qm clone 116 119 --name k8s-node2-centos7.8
apiserver.linuxsa.org 得hosts master ip 特别是节点上
修改 hostname
# 修改 hostname hostnamectl set-hostname your-new-host-name # 查看修改结果 hostnamectl status # 设置 hostname 解析 echo "127.0.0.1 $(hostname)" >> /etc/hosts

脚本
https://github.com/evan886/k8s-install
说明 一个放在master 另外的一个放在node 直接 执行 这个脚本是原作者的 在这里谢谢了
debian 11用这两个
有交互界面的 记得yes 还有 hostname什么的得先手工 deb_install_k8s_master.sh deb_install_k8s_node.sh
Centos7 用这两个
centos_install_k8s_master.sh centos_install_k8s_node.sh
Reference
debian
