Kubernetes scaling up not fast enough (for K8 1.17 or below)
8/23/2020
Kubernetes 1.18 has a very nice ability to change auto-scaling going up through the behavior and scaleUp set. For 1.17, there's a way to control downscaling. Is there a parallel way to scale up faster? We are expecting very variable loads and our cluster isn't scaling up fast enough.
I am not sure what other info to include. I've been searching through the docs, but I cannot find anything that points me in the right direction.

Not really.
Assuming you are referring to HPAs, you can define a behavior scaleUp Policy only if you are using K8s 1.18 or later (v2beta2 HPA API). For example:
behavior:
scaleDown:
stabilizationWindowSeconds: 300
policies:
- type: Percent
value: 100
periodSeconds: 15
scaleUp: 👈
stabilizationWindowSeconds: 0
policies:
- type: Percent
value: 100
periodSeconds: 15
- type: Pods
value: 4
periodSeconds: 15
selectPolicy: Max
