Question

as We know we can autoscale on pods so here actually I have 2 question:
1. How to autoscaling nodes on kubernetes ?
2. How to trigger autoscaling group with AWS ?

Answer 1

If you go to the AWS ASG in the web console and select the minion ASG

example: https://us-west-2.console.aws.amazon.com/ec2/autoscaling/home?region=us-west-2#AutoScalingGroups:id=kubernetes-dev-minion-group-us-west-2a;view=details

Then edit the ASG's min,max you should get more/less nodes:

adjusting the num nodes in ASG
