How to update Virtual machine scale set

Question

Hi all,
When I created Azure Kubernetes Service from Azure Portal I also created a Virtual machine scale set (vmss) , I set min node = 1 , max node = 2 , how can I change this policy ?

I have another question in the margins , according to my calculation , 1 Standard_B2ms node is enough resource for my pods.
I create first pod1 for develope environment , then create 2 more pods for production environment , pod2 was create fine.
When pod3 was being initialized , it gave error "insufficient cpu" , vmss scale out second node automatically, then pod3 was created

How can I check reason, How do I know when my AKS needs more resources from vmss, where is the calculation formula/documentation about it ?

Answer 1

I can define Custom autoscale condition with scale out and scale in rules now, the number of node is decreased, it used manual scale at the beginning.
