HPA configuration error

Questions

Hi team!

We are trying to configure the HPA (Horizontal Pod Autoscaler) for a DB-less Kong Ingress Controller with a Helm upgrade with the following values.yaml:

autoscaling:
enabled: true
minReplicas: 3
maxReplicas: 5
targetCPUUtilizationPercentage: 80

Our:

autoscaling:
enabled: true
minReplicas: 3
maxReplicas: 5

resources:
limits:
cpu: 2
memory: 3G
requests:
cpu: 500m
memory: 300Mi

and with both configuration in the kubernetes cluster the HPA remains in the following state:

NAME REFERENCE TARGETS MINPODS MAXPODS REPLICAS AGE
kong-kong Deployment/kong-kong /80% 3 5 3 13d

and I get the following warning message:

failed to get cpu utilization: missing request for cpu

Here some complementary information:

-Kubernetes cluster: AKS
-Helm chart version: kong-1.15.1
-App Version: 2.3
-Helm config reference file: charts/charts/kong/values.yaml at main · Kong/charts · GitHub
thanks in advance for your help.

Regards,

CZ

Resource configuration is per-container, so you’ll need to make sure that you’ve set limits for both the Kong container and controller container. The controller is pretty lightweight and doesn’t require high resource requests.
