hamster.yaml

# Based on https://github.com/kubernetes/autoscaler/blob/master/vertical-pod-autoscaler/examples/hamster.yaml
# This config creates a deployment with two pods, each requesting 100 millicores
# and trying to utilize slightly above 500 millicores (repeatedly using CPU for
# 0.5s and sleeping 0.5s).
# It also creates a corresponding Vertical Pod Autoscaler that adjusts the
# requests.
# Note that the update mode is left unset, so it defaults to "Auto" mode.
