+# 2. 登录新VM
+
+在Azure上成功添加新VM后,新VM会有一个Private Ip
+

+
+基于Freeleaps堡垒机登录新VM
+
+1. 登录Freeleaps堡垒机
+```commandline
+ssh -o StrictHostKeyChecking=no -l xxxx@mathmast.com jumper.mathmast.com # 需要找jet添加堡垒机登录权限并且询问ssh密码
+
+```
+![img_6.png](asserts/img_6.png)
+
+2. 在Freeleaps堡垒机上登录新VM
+
+```commandline
+ssh freeleaps@10.10.1.4 # 密码是你添加VM时设置的密码
+```
+![img_7.png](asserts/img_7.png)
+
+# 3. 为新VM加域
+> 加域是为了确保可以通过 xxx@mathmast.com账号登录新VM
+
+加域流程参考:https://learn.microsoft.com/zh-cn/entra/identity/domain-services/join-ubuntu-linux-vm
+
+不太确认的配置值,可以登录一个已经配置好的机器,参考上面的配置
+
+关键配置值参考如下
+
+![img_8.png](asserts/img_8.png)
+
+下面这一步需要为找好wwwadmin@MATHMAST.COM设置密码,密码就用Freeleaps@2021
+![img_9.png](asserts/img_9.png)
+
+```commandline
+# 使用域账号登录新节点
+sudo ssh -l wwwadmin@mathmast.com 10.10.1.4
+```
+![img_11.png](asserts/img_11.png)
+
+至此,新VM可以通过域账号登录了
+
+# 4. 将新机器添加为K8s节点
+> 需要在堡垒机jumper.mathmast.com上执行
+参考：[README.md](ansible/README.md)

 ## How to use ?
 
 ### Cluster Scaling
+> First execute `init-cluster.sh` to initialize the environment and execute `source venv/bin/activate` to activate the virtual environment
 
+> Ansible version needs to be between 2.16.4 and 2.17.0
 If you want to scale nodes in cluster, you can execute script `upgrade-cluster.sh` after environment initialized.
