I'm using kOps 1.26.3 and Kubernetes 1.26.5, running on AWS. After upgrading with kops upgrade cluster, metrics server stopped working.
It is installed using this on cluster manifest:
metricsServer:
enabled: true
Some resources, like the service, are created. But there are no metric-server pods, nor deployments:
$ kubectl get service metrics-server -n kube-system

Since there are no pods, I don't know where to look for logs. I tried to terminate the instances and let kOps recreate them several times, with the same result.
