I wanted to setup HPA for a deployment on my kubernetes cluster (1.14.0 on bare metal) so I followed the instructions to setup metrics-server here: https://github.com/kubernetes-sigs/metrics-server.

After deploying metrics-server, I am able issue commands like kubectl top nodes and deploy HPA's using kubectl autoscale deployment <deployment-name> --min=1 ...

Currently, the issue I am facing is the HPA's created from kubectl autoscale ... seem to be deleted automatically for some reason after around 4-5 mins. So, I feel like there is some important information/step I am missing related to HPA on kubernetes? But I couldn't find any further information related to this particular issue when searching online...
