Error when deploying - Githubissues

IQHT-DGH commented 4 months ago

I have just created a new AKS Cluster, and upon installing metrics server so that we are able to implement HPA.

Upon running the kubectl command...

It appeared to get almost to the end and the following appeared...

The Deployment "metrics-server" is invalid:

spec.template.spec.containers[0].resources.requests: Invalid value: "100m": must be less than or equal to cpu limit of 45m
spec.template.spec.containers[0].resources.requests: Invalid value: "200Mi": must be less than or equal to memory limit of 59Mi

Environment:

Kubernetes distribution (GKE, EKS, Kubeadm, the hard way, etc.): Azure AKS
Container Network Setup (flannel, calico, etc.): Calico
Kubernetes version (use kubectl version): 1.29.0

hi, @IQHT-DGH maybe you can check if there are any resource limits like LimitRange configured in the cluster?

IQHT-DGH commented 3 months ago

Hi,

Thank you for your assistance, at the time of reporting this issue this was a freshly created AKS server where no specific limit ranges have been created by ourselves. Having reviewed the cluster again this morning I am able to see two metrics server pods in the kube-system namespace (although it isn't working correctly, and we'd love to be able to get HPA working) and there are no limit ranges imposed see images from lens...

It looks like the same issue as this one. https://github.com/kubernetes-sigs/metrics-server/issues/1205. Looks like it's AKS related.
