Microk8s实例创建

背景说明

multipass创建的Ubuntu虚拟机实例可以安装Microk8s减少对宿主机环境的污染，做到即用即创建不用即回收。

解决方案实例创建

创建一个虚拟机来运行 MicroK8s。建议至少 4 G 的 RAM 和 40G 存储，可以将该参数传递给启动的命令行

hanlongjie  ~  multipass launch 22.04 --name microk8s --cpus 6  --mem 8G --disk 100G
Launched: microk8s

超级用户

通过命令更改超级管理员密码

ubuntu@microk8s-singleton:~$ sudo passwd
New password:
Retype new password:
passwd: password updated successfully
ubuntu@microk8s-singleton:~$ su root
Password:
root@microk8s-singleton:/home/ubuntu#

进入实例

 hanlongjie  ~  multipass shell microk8s
