This is the assignment

Build a simple hello world web server that scales based on the number of http requests

received. The number of http requests and pods will need to be exported and accessible real

time in a dashboard - feel free to use any of the monitoring tools out there.

kubectl autoscale deployment hello-world --min=1 --max=3 --cpu-percent=50 horizontalpodautoscaler.autoscaling/hello-world autoscaled

[GOLA MANOJ]

Http requests is a custom metric. So we need to expose custom metrics in the cluster and use hpa to scale . This can be done by using Prometheus adapter, but we need to expose that metric from Prometheus then Prometheus adapter will capture it. That part I am unable to configure

I think you need ingress infront of your app to track down http requests… or use istio ingress gateway to count No of http requests… 

But I’m stuck at auto scaling based on this metric…
