I can use auto-scaler in local minikube, but after deploying to ubuntu in aws cloud, I used the same command, the auto-scaler can not reduce the pod automatically. In local minikube, in order to user auto-scaler, I have to install heapster, may I ask in order to run in cloud ubuntu, what do I need to install so as to make auto-scaler working? Thanks
heapster is now depracted : https://github.com/kubernetes-retired/heapster
To enable auto-scaling on your cluster you can use HPA(horizontal pod auto-scaler) and you can also install metrics server to check all metrics.
